-## Initialize the Engine
-
-### engineResourcePath
-
-* `static` engineResourcePath: *string*
-
-  Manually specifies the URL of Barcode Reader SDK engine (WASM) . The property needs to be set before [loadWasm](#loadwasm).
-
-  ```js
-  Dynamsoft.DBR.BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.5/dist/";
-  await Dynamsoft.DBR.BarcodeReader.loadWasm();
-  ```
-
-<br />
-
-### _bUseFullFeature
-
-* `static` _bUseFullFeature: *boolean* = false
-
-  Whether to use full WASM engine. The property needs to be set before [loadWasm](#loadwasm). The default is 'false'.
-
-   ```js
-   DBR.BarcodeReader._bUseFullFeature = true;
-   await DBR.BarcodeReader.loadWasm();
-   ```
-   Learn more about [differences between compact and full WASM engines](../user-guide/?ver=8.2.5#specify-which-engine-to-use).
-
-<br />
-
-### isLoaded
-
-* `static` isLoaded&#40;&#41;: *boolean*
-
-  Checks if the decoding module is loaded.
-
-<br />
-
-### loadWasm
-
-* `static` loadWasm&#40;&#41;: *Promise&lt;void&gt;*
-
-  Before most operations, `loadWasm` needs to be excuted firstly.
-
-  Most time, you do not need excute `loadWasm` manually. Because when you excute [createInstance](#createinstance), `loadWasm` will be excuted implicitly.
- 
-  Some properties can't be changed after `loadWasm`.
- 
-  Calling `loadWasm` in advance can avoid the long wait when `createInstance`. 
- 
-  ```js
-  window.addEventListener('DOMContentLoaded', (event) => {
-     DBR.BarcodeReader.loadWasm();
-   });
-  ```
-
-<br />
-
-## Create and Destroy Instance
-
-### bDestroyed
-
-* bDestroyed: *boolean*
-
-  Indicates whether the instance has been destroyed.
-
-<br />
-
-### createInstance
-
-* `static` createInstance&#40;&#41;: *Promise&lt;[BarcodeReader](#barcodereader)&gt;*
-
-  Create a `BarcodeReader` instance.
-
-   ```js
-   let reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-   ```
-
-<br />
-
-### destroy
-
-* destroy&#40;&#41;: *Promise&lt;void&gt;*
-
-  Destroies the `BarcodeReader` instance. If your page needs to create new instances from time to time, don't forget to destroy unused old instances to avoid possible memory leaks.
-
-<br />
-
-## Decode Barcode
-
-### decode
-
-* decode &#40;source: *[Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) &#124; [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) &#124; [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) &#124; [Uint8Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) &#124; [Uint8ClampedArray](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8ClampedArray)*<br />
-  
-  *&#124; [HTMLImageElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLImageElement) &#124; [HTMLCanvasElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement) &#124; [HTMLVideoElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLVideoElement)*<br />
-  
-  *&#124; string*&#41;: *Promise&lt;[TextResult](./interface/TextResult.md)&#91;&#93;&gt;*
-
-  Decodes barcodes from an image.
-
-  The main decoding method can accept a variety of data types, including binary data, images, base64 (with MIME), URL, etc.
-
-  The image format can be `png`, `jpeg`, `bmp`, `gif` and a few others (some browsers support `webp`, `tif`).
-
-  ```js
-  let results = await reader.decode(blob);
-  for(let result of results){
-      console.log(result.barcodeText);
-  }
-
-  let results2 = await reader.decode(htmlImageElement);
-  let results2 = await reader.decode(url);
- 
-  // like `data:image/png;base64,iV************`
-  let results3 = await reader.decode(strBase64WithMime);
-  ```
-
-  And you can get a frame from the `HTMLVideoElement` for barcode scanning.
-
-  ```js
-  // The frame currently played will be decoded.
-  let results;
-  try{
-    results = await reader.decode(htmlVideoElement);
-  }catch(ex){

-### Return Value
-
-A promise resolving to the created `BarcodeReader` object.
-
-### Code Snippet
-
-```js
-let reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-```

-
-```typescript
-destroyContext(): void
-```
-

-
-`source` : specifies the image to decode. The supported image formats include `png` , `jpeg` , `bmp` , `gif` and a few others (some browsers support `webp` , `tif` ). Also note that the image can be specified in a lot of ways including binary data, base64 string (with MIME), URL, etc.
-
-> To speed up the reading, the image will be scaled down when it exceeds a size limit either horizontally or vertically.

-> * The limit is 2048 pixels on mobile devices and 4096 on other devices.
-> * If the template "dense" or "distance" is used, the limit is 4096 regardless of which device is used.
->
-> Therefore, setting a very high resolution will not help with the scanning.

-### Return Value
-
-A promise resolving to the created `BarcodeReader` object.
-
-### Code Snippet
-
-```js
-let reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-```
-
-## destroyContext

-
-```typescript
-destroyContext(): void
-```
-
-### Code Snippet

-```
-
-> If the content in the binary data is raw img data, such as `RGBA` , use [decodeBuffer()](#decodebuffer) instead.
-
-### Parameters
-
-`source` : specifies the image to decode. The supported image formats include `png` , `jpeg` , `bmp` , `gif` and a few others (some browsers support `webp` , `tif` ). Also note that the image can be specified in a lot of ways including binary data, base64 string (with MIME), URL, etc.
-
-> To speed up the reading, the image will be scaled down when it exceeds a size limit either horizontally or vertically.
->
-> * The limit is 2048 pixels on mobile devices and 4096 on other devices.
-> * If the template "dense" or "distance" is used, the limit is 4096 regardless of which device is used.
->
-> Therefore, setting a very high resolution will not help with the scanning.

-```typescript
-destroyContext(): void
-```
-
-### Code Snippet

-```
-
-> If the content in the binary data is raw img data, such as `RGBA` , use [decodeBuffer()](#decodebuffer) instead.
-
-### Parameters
-
-`source` : specifies the image to decode. The supported image formats include `png` , `jpeg` , `bmp` , `gif` and a few others (some browsers support `webp` , `tif` ). Also note that the image can be specified in a lot of ways including binary data, base64 string (with MIME), URL, etc.
-
-> To speed up the reading, the image will be scaled down when it exceeds a size limit either horizontally or vertically.
->
-> * The limit is 2048 pixels on mobile devices and 4096 on other devices.
-> * If the template "dense" or "distance" is used, the limit is 4096 regardless of which device is used.
->
-> Therefore, setting a very high resolution will not help with the scanning.
-
-### Return Value
-
-A promise resolving to an array of `TextResult` object that contains the barcode results found in this image.

-```
-
-### Arguments
-
-`results` : an array of `TextResult` object that contains the barcode results in this image.
-
-### Code Snippet
-
-```js
-let reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-let enhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance();
-let options = {
-    resultsHighlightBaseShapes: Dynamsoft.DCE.DrawingItem

-};
-await reader.startScanning(true);
-```
-
-### See Also
-
-* [TextResult](./interface/TextResult.md)
-* [onUniqueRead](#onUniqueRead)
-
-## startScanning
-
-Open the camera and starts continuous scanning of incoming images.
-
-```typescript
-startScanning(appendOrShowUI?: boolean): Promise<ScannerPlayCallbackInfo>;
-```
-
-### Parameters
-
-`appendOrShowUI` : this parameter specifies how to handle the UI that comes with the bound `CameraEnhancer` instance. When set to true, if the UI doesn't exist in the DOM tree, the `CameraEnhancer` instance will append it in the DOM and show it; if the UI already exists in the DOM tree but is hidden, it'll be displayed. When not set or set to false, it means not to change the original state of that UI: if it doesn't exist in the DOM tree, nothing shows up on the page; if it exists in the DOM tree, it may or may not show up depending on its original state.
-
-### Return Value
-
-A promise resolving to a `ScannerPlayCallbackInfo` object which contains the resolution of the video.
-
-### Code Snippet
-
-```js
-let reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-let enhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance();
-let options = {
-    resultsHighlightBaseShapes: Dynamsoft.DCE.DrawingItem

-
-### Parameters
-
-`hideUI` : this parameter specifies how to handle the UI that comes with the bound `CameraEnhancer` instance. When set to true, if the UI doesn't exist in the DOM tree or it exists but is hidden, nothing is done; if the UI already exists in the DOM tree and is shown, it'll be hidden. When not set or set to false, it means not to change the original state of that UI: if it doesn't exist in the DOM tree, nothing happens; if it exists in the DOM tree, it may or may not be hidden depending on its original state.

-# Javascript API Reference - `BarcodeReader` Properties
-
-| Property             | Description |
-|----------------------|-------------|
-| [_bUseFullFeature](#_busefullfeature) | If set to `false`, use the compact-featured WASM module. |
-| `bDestroyed` | Indicates whether a `BarcodeReader` object has been destroyed. | 
-| `bSaveOriCanvas` | If set to `true`, save the original image to canvas. | 
-| `oriCanvas` | The original canvas element. | 
-
----
-
-## _bUseFullFeature
-
-Set usage of compact or full featured SDK. If set to `false`, use the compact-featured WASM module.
-
-*Note: this API may change in the future.*
-
-```javascript
-Dynamsoft.BarcodeReader._bUseFullFeature = Boolean
-```
-
-### Default Value
-
-`false` for web
-
-### Sample
-
-```javascript
-Dynamsoft.BarcodeReader._bUseFullFeature = false;
-await Dynamsoft.BarcodeReader.loadWasm();
-```
-
-### :+1: Tips and Tricks
-
-* Check out [what features are included](../../user-guide/features-requirements.md#compact-and-full-editions) in compact and full version.
-* This property **must** be set before [loadWasm](methods/initialize-and-destroy.md#loadwasm).
-* We recommend using the compact version in video decoding for its small size and quick initialization.
-* This property cannot be set in NodeJS and will always use the fully featured version.

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.scanner.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUnduplicatedRead = txt => console.log(txt);
-await scanner.show();
-```
-

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.scanner.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUnduplicatedRead = txt => console.log(txt);
-await scanner.show();
-```
-
-

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.scanner.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUnduplicatedRead = txt => console.log(txt);
-await scanner.show();
-```

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-
-## singleFrameMode
-
-Returns or sets the status of the single-frame mode. If enabled, the video input will not be played and the user can choose to take a picture with the system camera (mobile only) or select an existing image for barcode reading.
-
-Because the system camera of a mobile device can provide pictures with better quality, the API is useful when facing complex scenarios such as reading the dense PDF417 code on a driver license.
-
-The single-frame mode can only be enabled or disabled before the video input starts playing.
-
-If the browser does not support the `MediaDevices`/`getUserMedia` API, the `singleFrameMode` will be set as `true` automatically when the API `createInstance()` is called.

-```typescript
-singleFrameMode: boolean
-```
-
-**Code Snippet**
-
-```js

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-## resumeScan
-
-Resumes the decoding process.
-
-```typescript
-resumeScan(): void
-```
-
-## singleFrameMode
-
-Returns or sets the status of the single-frame mode. If enabled, the video input will not be played and the user can choose to take a picture with the system camera (mobile only) or select an existing image for barcode reading.
-
-Because the system camera of a mobile device can provide pictures with better quality, the API is useful when facing complex scenarios such as reading the dense PDF417 code on a driver license.
-
-The single-frame mode can only be enabled or disabled before the video input starts playing.
-
-If the browser does not support the `MediaDevices`/`getUserMedia` API, the `singleFrameMode` will be set as `true` automatically when the API `createInstance()` is called.
-
-```typescript
-singleFrameMode: boolean
-```
-
-**Code Snippet**
-
-```js

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/?ver=latest#customize-the-ui-optional).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-```
-
-**Arguments**
-
-`txt` : a string that holds the barcode text. 
-
-`result` : a `TextResult` object that contains more detailed info.

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/?ver=latest#customize-the-ui-optional).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-```typescript
-show(): Promise<ScannerPlayCallbackInfo>
-```
-
-**Return value**

-
-Returns or sets the status of single frame mode. If enabled, the video input will not be played and the user can choose to take a picture with the system camera (mobile only) or select an existing image from the photo library for barcode reading.
-
-Because the system camera of a mobile device can provide pictures with better quality, the API is useful when facing complex scenarios such as reading the dense PDF417 code on a driver license.
-
-The single-frame mode can only be enabled or disabled before the video input starts playing (before `scanner.show()` is called).
-
-If the browser does not support the `MediaDevices`/`getUserMedia`, `singleFrameMode` will be set as `true` automatically when `createInstance()` is called.

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/?ver=latest#customize-the-ui-optional).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-## onUniqueRead
-
-Specifies an event handler which fires when a new, unduplicated barcode is found.
-
-The library keeps each barcode result (type and value) in the buffer for a period of time (can be set with [duplicateForgetTime](./interface/ScanSettings.md)) during which if a new result is an exact match, it's seen as a duplicate and will again be kept for that period of time while the old result is removed and so on.

-```typescript
-show(): Promise<ScannerPlayCallbackInfo>
-```
-
-**Return value**
-
-A promise resolving to a `ScannerPlayCallbackInfo` object.
-
-**Code Snippet**

-## open
-
-Binds UI, turns on the camera and starts decoding.
-
-> This method does not change the original state of the UI: if it doesn't exist in the DOM tree, nothing shows up on the page; if it exists in the DOM tree, it may or may not show up depending on its original state.
-
-```typescript
-open(): Promise<void>
-```
-
-**Return value**
-
-A promise resolving to a `ScannerPlayCallbackInfo` object.
-
-**Code Snippet**

-
-## pauseScan
-
-Pause continuous scanning but keep the video stream.
-
-```typescript
-pauseScan(options?: object): void;
-```
-
-**Parameters**
-
-`options`: Options to configure how the pause works. At present, it only contains one property `keepResultsHighlighted` which, when set to **true**, will keep the barcodes found on the frame (at the time of the pause) highlighted.
-
-**See also**
-
-* [resumeScan](#resumeScan)

-**See also**
-
-* [pauseScan](#pauseScan)
-
-## singleFrameMode
-
-Returns or sets the status of single frame mode. If enabled, the video input will not be played and the user can choose to take a picture with the system camera (mobile only) or select an existing image from the photo library for barcode reading.
-
-Because the system camera of a mobile device can provide pictures with better quality, the API is useful when facing complex scenarios such as reading the dense PDF417 code on a driver license.
-
-The single-frame mode can only be enabled or disabled before the video input starts playing (before `scanner.show()` is called).
-
-```typescript
-singleFrameMode: boolean
-```
-
-**Default value**
-
-In general, the default value is `false`. But if the browser does not support the `MediaDevices`/`getUserMedia`, it will be set as `true` automatically when `createInstance()` is called.
-
-**Code Snippet**
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-if(didVideoStreamFailWhenReadingDriverLicenses){
-  scanner.singleFrameMode = true;
-  await scanner.show();
-}
-```
-
-## getScanSettings
-
-Returns the current scan settings.
-
-```typescript
-getScanSettings(): Promise<ScanSettings>
-```
-
-**Return value**
-
-A promise resolving to a `ScanSettings` .
-
-**Code Snippet**
-
-```js
-let scanSettings = await scanner.getScanSettings();
-scanSettings.intervalTime = 50;
-scanSettings.duplicateForgetTime = 1000;

-# BarcodeScanner for Video
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.ui.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/?ver=latest#customize-the-ui-optional).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties which will not be covered in this article.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```

-## onUniqueRead
-
-Specifies an event handler which fires when a new, unduplicated barcode is found.
-
-The library keeps each barcode result (type and value) in the buffer for a period of time (can be set with [duplicateForgetTime](./interface/ScanSettings.md)) during which if a new result is an exact match, it's seen as a duplicate and will again be kept for that period of time while the old result is removed and so on.

-onUniqueRead: (txt: string, result: TextResult) => void
-```
-
-**Arguments**

-
-```typescript
-show(): Promise<ScannerPlayCallbackInfo>
-```
-
-**Return value**
-

-
-**Code Snippet**
-
-```js
-scanner.onUniqueRead = (txt, result) => {
-    alert(txt);

-
-* [close](#close)
-
-## open
-
-Binds UI, turns on the camera and starts decoding.
-
-> This method does not change the original state of the UI: if it doesn't exist in the DOM tree, nothing shows up on the page; if it exists in the DOM tree, it may or may not show up depending on its original state.
-
-```typescript
-open(): Promise<void>
-```
-
-**Return value**
-
-A promise resolving to a `ScannerPlayCallbackInfo` object.
-
-**Code Snippet**

-
-## isOpen
-
-Indicates whether the camera is turned on.
-
-```typescript
-isOpen(): boolean
-```
-
-**Return value**
-
-A boolean indicates whether the camera is turned on.
-
-## pauseScan
-
-Pause continuous scanning but keep the video stream.
-
-```typescript
-pauseScan(options?: object): void;
-```
-
-**Parameters**
-
-`options`: Options to configure how the pause works. At present, it only contains one property `keepResultsHighlighted` which, when set to **true**, will keep the barcodes found on the frame (at the time of the pause) highlighted.
-
-**See also**
-
-* [resumeScan](#resumescan)
-
-## resumeScan
-
-Resumes the decoding process.
-
-```typescript
-resumeScan(): void
-```
-
-**See also**
-
-* [pauseScan](#pausescan)
-
-## singleFrameMode
-
-Returns or sets the status of single frame mode. If enabled, the video input will not be played and the user can choose to take a picture with the system camera (mobile only) or select an existing image from the photo library for barcode reading.
-
-Because the system camera of a mobile device can provide pictures with better quality, the API is useful when facing complex scenarios such as reading the dense PDF417 code on a driver license.
-
-> It's important to note that it will behave differently in different environments:
- > - false: Stream the camera in the browser.
- > - true \| "image": Prompt the user to select a local image.
- > - "camera":
- >   - On desktop: Prompt the user to select a local image.
- >   - On mobile devices: Invoke the system camera.
-
-The single-frame mode can only be enabled or disabled before the video input starts playing (before `scanner.open()` is called).
-
-```typescript
-singleFrameMode: boolean | "image" | "camera";
-```
-
-**Default value**
-
-In general, the default value is `false`. But if the browser does not support the `MediaDevices`/`getUserMedia`, it will be set as `true` automatically when `createInstance()` is called.
-
-**Code Snippet**
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.singleFrameMode = true;
-await scanner.show();
-```
-
-## getScanSettings
-
-Returns the current scan settings.
-
-```typescript
-getScanSettings(): Promise<ScanSettings>
-```
-
-**Return value**
-
-A promise resolving to a `ScanSettings` .
-
-**Code Snippet**
-
-```js
-let scanSettings = await scanner.getScanSettings();
-scanSettings.intervalTime = 50;
-scanSettings.duplicateForgetTime = 1000;
-await scanner.updateScanSettings(scanSettings);
-```
-

-# Javascript API Reference - `BarcodeScanner` Accessors
-
-| Accessors            | Description |
-|----------------------|-------------|
-| [defaultUIElementURL](#defaultuielementurl) | Get or set the default scanner UI. | 
-| [singleFrameMode](#singleframemode) | If set to `true`, single video frames will be used instead of a continuous video stream. | 
-| [soundOnSuccessfulRead](#soundonsuccessfulread) | Get or set the sound to play when a barcode is read successfully. | 
-
-### Inherited Accessors from `BarcodeReader` 
-
-| Accessors            | Description |
-|----------------------|-------------|
-| [engineResourcePath](../BarcodeReader/accessors.md#engineresourcepath) | Get or set the engine (WASM) location. | 
-| [productKeys](../BarcodeReader/accessors.md#productkeys) | Get or set the Dynamsoft Barcode Reader SDK product keys. | 
-| [version](../BarcodeReader/accessors.md#version) | Get current version. |
-
-## defaultUIElementURL
-
-Get or set the default scanner UI. The default scanner UI is defined in the file `dist/dbr.scanner.html`. Follow [these steps](../../user-guide/basic-customizations.md#customizing-the-ui) to customize the UI. 
-
-```javascript
-defaultUIElementURL = 'url'
-```
-
-### Property Value
-
-`url` *string*  
-
-### :+1: Tips and Tricks 
-
-* Be sure to set `defaultUIElementURL` before you call `createInstance`.
-
-## singleFrameMode
-
-Get or set the camera mode. If `true`, single video frames will be used instead of a continuous video stream. It's especially useful for cameras that lack webcam access (lack of WebRTC support, e.g. Chrome on iOS).
-
-```javascript
-singleFrameMode = bool;
-``` 
-
-### Property Value
-
-`bool` *boolean* 
-
-### Sample
-
-```javascript
-let scanner = await Dynamsoft.BarcodeScanner.createInstance();
-scanner.singleFrameMode = true; // use singleFrameMode anyway
-scanner.show();
-```
-
-### :+1: Tips and Tricks 
-
-* `singleFrameMode` is based on WebRTC support, not actual camera connection. In other words, if a browser supports WebRTC, it won't be using `singleFrameMode` by default even when there is no camera attached.
-
-* By default, when the default UI is used, a camera icon will appear for the `singleFrameMode` which is defined by a SVG (`className` is `dbrScanner-bg-camera`). If you have customized the UI, you will have to provide your own UI implementation for this mode.
-
-## soundOnSuccessfulRead
-
-Get or set the sound played when a barcode is read successfully. 
-
-```javascript
-soundOnSuccessfulRead = audio
-```
-
-### Property Value
-
-`audio` *HTMLAudioElement*  
-
-### Sample
-
-```javascript
-scanner.soundOnSuccessfulRead = new Audio("./pi.mp3");
-```

-
-## defaultUIElementURL
-
-Get or set the default scanner UI. The default scanner UI is defined in the file `dist/dbr.scanner.html`. Follow [these steps](../../user-guide/basic-customizations.md#customizing-the-ui) to customize the UI. 
-
-```javascript
-defaultUIElementURL = 'url'
-```
-
-### Property Value
-
-`url` *string*  
-
-### :+1: Tips and Tricks 
-
-* Be sure to set `defaultUIElementURL` before you call `createInstance`.
-
-## singleFrameMode
-
-Get or set the camera mode. If `true`, single video frames will be used instead of a continuous video stream. It's especially useful for cameras that lack webcam access (lack of WebRTC support, e.g. Chrome on iOS 14.2 and below).
-
-```javascript
-singleFrameMode = bool;
-``` 
-
-### Property Value
-
-`bool` *boolean* 
-
-### Sample
-
-```javascript
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.singleFrameMode = true; // use singleFrameMode anyway
-scanner.show();
-```
-
-### :+1: Tips and Tricks 
-
-* `singleFrameMode` is based on WebRTC support, not actual camera connection. In other words, if a browser supports WebRTC, it won't be using `singleFrameMode` by default even when there is no camera attached.
-
-* By default, when the default UI is used, a camera icon will appear for the `singleFrameMode` which is defined by a SVG (`className` is `dbrScanner-bg-camera`). If you have customized the UI, you will have to provide your own UI implementation for this mode.
-
-## soundOnSuccessfulRead
-
-Get or set the sound played when a barcode is read successfully. 
-
-```javascript
-soundOnSuccessfulRead = audio
-```
-
-### Property Value
-
-`audio` *HTMLAudioElement*  
-
-### Sample
-
-```javascript
-scanner.soundOnSuccessfulRead = new Audio("./pi.mp3");
-```
-
-## bPlaySoundOnSuccessfulRead
-
-Set when a sound is played if a barcode is read successfully. Default value is `false`, which does not play a sound. 
-
-Use `frame` or `true` to play a sound when any barcode is found within a frame. Use `unduplicated` to play a sound only when any unique/unduplicated barcode is found within a frame.
-
-```javascript
-scanner.bPlaySoundOnSuccessfulRead = false;
-
-scanner.bPlaySoundOnSuccessfulRead = true;
-
-scanner.bPlaySoundOnSuccessfulRead = "frame";
-
-scanner.bPlaySoundOnSuccessfulRead = "unduplicated";
-```
-
-## barcodeFillStyle
-
-Set the style used when filling in the located barcode.
-
-```javascript
-barcodeFillStyle = "rgba(red, green, blue, alpha)"
-```
-
-### Property Values
-
-- `red` *number*  
-- `green` *number*  
-- `blue` *number*  
-- `alpha` *number*
-
-## barcodeStrokeStyle
-
-Set the style of the located barcode border.
-
-```javascript
-barcodeStrokeStyle = "rgba(red, green, blue, alpha)"
-```
-
-### Property Values
-
-- `red` *number*  
-- `green` *number*  
-- `blue` *number*  
-- `alpha` *number*
-
-## regionMaskFillStyle
-
-Set the style used when filling the mask beyond the region.
-
-```javascript
-regionMaskFillStyle = "rgba(red, green, blue, alpha)"
-```
-
-### Property Values
-
-- `red` *number*  
-- `green` *number*  
-- `blue` *number*  
-- `alpha` *number*
-
-## regionMaskStrokeStyle
-
-Set the style of the region border.
-
-```javascript
-regionMaskStrokeStyle = "rgb(red, green, blue)"
-```
-
-### Property Values
-
-- `red` *number*  
-- `green` *number*  
-- `blue` *number*  
-
-## onFrameRead
-
-This event is triggered when a single frame has been scanned. The results object contains all the barcode results that the reader was able to decode.
-
-### Type Declaration

-# Initialization Control
-
-The following static methods and properties help to set up the runtime environment for the library.
-
-- [Initialization Control](#initialization-control)
-  - [engineResourcePath](#engineresourcepath)
-  - [loadWasm](#loadwasm)
-    - [Return Value](#return-value)
-  - [isWasmLoaded](#iswasmloaded)
-  - [version](#version)
-  - [detectEnvironment](#detectenvironment)
-  - [onWarning](#onwarning)
-
-## engineResourcePath
-
-Specifies the path to find the engine(s). The property needs to be set before [loadWasm](#loadwasm). If not specified, the library will try to find the engine in the same location as the main JavaScript file (dbr.js).
-
-```typescript
-static engineResourcePath: string
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-await Dynamsoft.DBR.BarcodeReader.loadWasm();
-```
-
-## loadWasm
-
-Downloads and compiles the engine to get it loaded/ready for a `BarcodeReader` or `BarcodeScanner` instance to be created. You can call this API to silently set the operating environment of the library as soon as the page is loaded, avoiding unnecessary waiting time when using the library later.
-
-If this API is not called beforehand, it will be called automatically when creating an instance of `BarcodeReader` or `BarcodeScanner`.
-
-```typescript
-static loadWasm(): Promise<void>
-```
-
-### Return Value
-
-A promise that resolves when the operation succeeds.
-
-**Code Snippet**
-
-```js
-window.addEventListener('DOMContentLoaded', (event) => {
-    Dynamsoft.DBR.BarcodeReader.loadWasm();
-});
-```
-
-**:+1: Tips and Tricks **
-
-* [How to get rid of the delay when opening the camera?]({{ site.faq_js }}delay-when-open-camera.html)
-
-## isWasmLoaded
-
-Returns whether the engine is loaded/ready.
-
-```typescript
-static isWasmLoaded(): boolean
-```
-
-## version
-
-Returns the version of the library including the detailed version numbers of the engine and the main JavaScript code.
-
-The engine version is only valid after [loadWasm](#loadwasm) has been called.
-
-```typescript
-readonly static version: string
-```
-
-**Code Snippet**
-
-```js
-console.log(Dynamsoft.DBR.BarcodeReader.version);
-// loading...(JS 8.8.3.20211011)
-await Dynamsoft.DBR.BarcodeReader.loadWasm();
-console.log("When loaded..." + Dynamsoft.DBR.BarcodeReader.version);
-// 8.8.0.10403(JS 8.8.3.20211011)
-```
-
-## detectEnvironment
-
-Detects the current running environment and returns a report.
-
-```typescript
-static detectEnvironment(): Promise<any>
-```
-
-**Return value**
-
-A promise resolving to an object which contains some information of the current running environment.
-
-**Code Snippet**
-
-```js
-console.log(await Dynamsoft.DBR.BarcodeReader.detectEnvironment());
-// {"wasm":true, "worker":true, "getUserMedia":true, "camera":true, 
-// "browser":"Chrome", "version":90, "OS":"Windows"}
-```
-
-## onWarning
-
-A callback which is triggered when the running environment is not ideal. In this version, it may get triggered in two scenarios:
-
-1. If the page is opened from the disk
-2. The page is hosted in a HTTP site without SSL
-
-In both cases, the following warning is returned:
-
-```js
-{
-    id: 2,
-    message: "Not connected via SSL (HTTPS), the SDK may not work correctly."
-}
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeScanner.onWarning = warning => console.log(warning.message);
-```
-
-**See Also**
-
-[Warning](interface/warning.md)
-
-
-<!--
-## _bUseFullFeature
-
-Whether to use the full engine or the compact engine. The property needs to be set before [loadWasm](#loadwasm) or `createInstance`.
-
-```typescript
-static _bUseFullFeature: boolean
-```
-
-**Default value**
-
-`true`
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader._bUseFullFeature = true;
-await Dynamsoft.DBR.BarcodeReader.loadWasm();
-```

-
-# License Control
-
-The library provides flexible licensing options with the support of the following APIs
-
-* [license](#license)
-* [licenseServer](#licenseserver)
-* [sessionPassword](#sessionpassword)
-* [deviceFriendlyName](#devicefriendlyname)
-
-Deprecated APIs:
-
-* [organizationID](#organizationid)
-* [handshakeCode](#handshakecode)
-* [productKeys](#productkeys)
-
-## license
-
-An online license or an offline license can be set here. Most license formats are supported. Dynamsoft usually provides an online license. 
-
-`license` needs to be set before `createInstance()` or `loadWasm()`.
-
-```typescript
-static license: string
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.license =
-  "YOUR-ORGANIZATION-ID or YOUR-HANDSHAKECODE or AN-OFFLINE-LICENSE or ANY-OTHER-TYPE-OF-SUPPORTED-LICENSE-STRING";
-let scanner = await Dynamsoft.DBR.BarcodeReader.createInstance();
-```
-
-For convenience, you can even set `license` in the `script` tag.
-
-```html
-<script src="/dist/dbr.js" data-license=
-  "YOUR-ORGANIZATION-ID or YOUR-HANDSHAKECODE or AN-OFFLINE-LICENSE or ANY-OTHER-TYPE-OF-SUPPORTED-LICENSE-STRING"></script>
-```
-
-> Note:
->
-> **Handshake Code and Organization ID**
->
-> When you are using the online licenses, the license items can't be used directly. You need to use either a "Handshake Code" or an "Organization ID" instead.
-> 
-> The "Handshake Code" refers to an array of license items. When an "Handshake Code" is set, these license items will be consumed in a preset order.
->
-> When an  "Organization ID" is set, the default "Handshake Code" of the "Organization ID" will be used.
->
-> Generally, the first "Handshake Code" ever created for an organization is the default one. However, you can always configure another "Handshake Code" as the default.
->
-> "Handshake Codes" can be configured in the [customer portal](https://www.dynamsoft.com/lts/#/handshakeCodes).
-
-## licenseServer
-
-Specifies the URL(s) for the main and stand-by License Tracking Server(s). This is only required when you host the License Tracking Server(s) yourself. If nothing is set, the Server(s) hosted by Dynamsoft will be used.
-
-```typescript
-static licenseServer: string[] | string
-```
-
-**Code Snippet**
-
-```js
-// You can specify only the main server
-Dynamsoft.DBR.BarcodeReader.licenseServer = ["YOUR-OWN-MAIN-DLS"];
-
-//or you can specify both
-Dynamsoft.DBR.BarcodeReader.licenseServer = ["YOUR-OWN-MAIN-DLS", "YOUR-OWN-STANDBY-DLS"];
-```
-
-## sessionPassword
-
-Specifies a password to protect the [Handshake Code](#handshakeCode). If no Handshake Code is specified with the API `handshakeCode`, this password protects the default Handshake Code.
-
-The password can be set for each Handshake Code when it was first created and can be changed later by editing the configuration of the Code.
-
-```typescript
-static sessionPassword: string
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.sessionPassword = "YOUR-SESSION-PASSWORD";
-```
-
-## deviceFriendlyName
-
-static deviceFriendlyName: string
-
-Sets a human-readable name that identifies the device. This name will appear in the device details table when you check the statistics of the according Handshake Code or License Item.
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.deviceFriendlyName = "Harry-Potter-iPhone";
-```
-
-## organizationID
-
-**Please NOTE that this API is deprecated! Use [license](#license) instead.**
-
-When a license is purchased, it is registered to an Organization. This license is then hosted by a License Tracking Server which authorizes terminal devices and consumes the license. This API specifies which Organization you would like to acquire authorization from.
-
-```typescript
-static organizationID: string
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.organizationID = "YOUR-ORGANIZATION-ID";
-```
-
-## handshakeCode
-
-**Please NOTE that this API is deprecated! Use [license](#license) instead.**
-
-Licenses registered to the same Organization are grouped by Handshake Codes. When an Organization is specified by `organizationID`, the default Handshake Code will be used unless another Code is specified with this API.
-
-Generally, the first Handshake Code ever created for an organization is the default one. However, you can always make another Code default in the [customer portal](https://www.dynamsoft.com/lts/#/handshakeCodes).
-
-```typescript
-static handshakeCode: string
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.handshakeCode = "YOUR-HANDSHAKE-CODE";
-```
-
-## productKeys
-
-**Please NOTE that this API is deprecated! Use [license](#license) instead.**
-
-A product key is an alphanumeric string used as an offline license. If such a key is specified in your program, you do not need to specify anything else for licensing purposes.
-
-```typescript
-static productKeys: string
-```
-
-**Code Snippet**
-
-```js
-Dynamsoft.DBR.BarcodeReader.productKeys = "YOUR-PRODUCT-KEYS";
-```
-
-For convenience, you can even set `productKeys` in the `script` tag.
-
-```html
-<script src="/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-```

-#### :+1: Tips and Tricks 
-
-* `1` : If you have a blurry image, you can set `deblurLevel` to a larger value. The higher the value, the more effort the library will spend to decode images, but it may also slow down the recognition process. 
-
-* `2` : Setting `expectedBarcodesCount` to `0` represents an "unknown" count and the library will try to find *at least* one barcode. `1` will result in trying to find exactly one barcode. Once a barcode is found, the library will stop the localization process and perform barcode decoding. `n` means the library will try to find `n` barcodes. If the library only finds `m` where `m < n` barcode(s), it will try a different [localization algorithm]({{ site.enumerations }}parameter-mode-enums.html#localizationmode) until `n` barcodes are located, or all algorithms are tried. 
-
-* `3` : `0` means no limitation on the barcode text length.
-
-* `4` : `0` means no limitation on the result confidence.
-
-* `5` : If the shorter edge size is larger than the given threshold value, the library will calculate the required height and width of the barcode image and shrink the image to that size before localization. Otherwise, the library will perform barcode localization on the original image.
-
-* `6` : When the recognition result is not desired, you can set this parameter to skip certain processing stages.
-
-* `coverage` is the default setting for `BarcodeReader` and `speed` for `BarcodeScanner`. See [updateRuntimeSettings](BarcodeReader/methods/parameter-and-runtime-settings.md#updateRuntimeSettings)

-## BarcodeScanner
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and perform continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file "dbr.scanner.html". If used directly, the UI will fit the entire page and sit on top. There are a few ways to customize it, read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode]({{ site.js }}api-reference/BarcodeScanner-v8.4.0.html#singleframemode) which allows the user to select a still image or take a shot with the mobile camera for barcode scanning.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUnduplicatedRead = txt => console.log(txt);
-await scanner.show();
-```
-
-The `BarcodeScanner` is a child class of [BarcodeReader](./BarcodeReader.md) and inherits all its methods and properties. APIs not directly inherited include

-## BarcodeScanner
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and performs continuous barcode scanning on the incoming frames.
-
-The default built-in UI of each barcode scanner is defined in the file `dbr.ui.html` and it fits the entire page and sits on top. Read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](BarcodeScanner.md#singleframemode) which allows users to select a still image or take a shot with the camera for barcode scanning.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();

-
-## BarcodeScanner
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and performs continuous barcode scanning on the incoming frames.
-
-The default built-in UI of a barcode scanner object is defined in the file `dbr.ui.html`. The UI fits the entire page and sits on top. Read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](BarcodeScanner.md#singleframemode) which allows users to select a still image or take a shot with the camera for barcode scanning.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();

-## BarcodeScanner
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and performs continuous barcode scanning on the incoming frames.
-
-The default built-in UI of a barcode scanner object is defined in the file `dbr.ui.html`. The UI fits the entire page and sits on top. Read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](BarcodeScanner.md#singleframemode) which allows users to select a still image or take a shot with the camera for barcode scanning.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```
-
-The `BarcodeScanner` class is based on [BarcodeReader](./BarcodeReader.md) and inherits most of its methods and properties. The following APIs are different or unique:

-# JavaScript API Reference
-
-The Dynamsoft Barcode Reader JavaScript library comes with two primary classes: [BarcodeReader](#barcodereader) and [BarcodeScanner](#barcodescanner).
-
-## BarcodeReader
-
-A low-level barcode reader that processes still images and returns barcode results. The following code snippet shows its basic usage:
-
-```js
-let reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-let results = await reader.decode(imageSource);
-for(let result of results){
-  console.log(result.barcodeText);
-}
-```

-## BarcodeScanner
-
-A barcode scanner object gets access to a camera via the [MediaDevices](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface, then uses its built-in UI to show the camera input and performs continuous barcode scanning on the incoming frames.
-
-The default built-in UI of a barcode scanner object is defined in the file `dbr.ui.html`. The UI fits the entire page and sits on top. Read more on how to [Customize the UI](../user-guide/#customize-the-ui).
-
-Although a barcode scanner is designed to scan barcodes from a video input, it also supports a special mode called [singleFrameMode](BarcodeScanner.md#singleframemode) which allows users to select a still image or take a shot with the camera for barcode scanning.
-
-The following code snippet shows the basic usage of the `BarcodeScanner` class.
-
-```js
-let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-scanner.onUniqueRead = txt => console.log(txt);
-await scanner.show();
-```
-
-The `BarcodeScanner` class is based on [BarcodeReader](./BarcodeReader.md) and inherits most of its methods and properties. The following APIs are different or unique:
-

-### colourConversionModes
-
-Sets the modes and their correspondent priorities when the SDK is required to convert a colour image to a grayscale one.
-
-**Value Range** Please see the [EnumColourConversionMode](../enum/EnumColourConversionMode.md) items.
-
-**Default Value** `[CICM_GENERAL,CICM_SKIP,CICM_SKIP,CICM_SKIP,CICM_SKIP,CICM_SKIP,CICM_SKIP,CICM_SKIP]`
-
-### grayscaleTransformationModes
-
-This parameter should be mainly used when trying to read light on dark barcodes. By default, the SDK is configured to read dark on light barcodes.
-
-**Value Range** An array of [EnumGrayscaleTransformationMode](../enum/EnumGrayscaleTransformationMode.md) items.
-
-**Default Value** `[GTM_ORIGINAL,GTM_SKIP,GTM_SKIP,GTM_SKIP,GTM_SKIP,GTM_SKIP,GTM_SKIP,GTM_SKIP]`
-
-**Remarks** If you are primarily scanning dark on light barcodes, it is best to set the highest priority item in the array to `GTM_INVERTED`.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.grayscaleTransformationModes[0] = Dynamsoft.DBR.EnumGrayscaleTransformationMode.GTM_INVERTED;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### regionPredetectionModes
-
-This parameters helps speed up the recognition process by detecting regions of interest automatically. Pre-detection is based on the colour/grayscale distribution of each area, and then choosing areas of interest based on the priority of the region predetction modes.
-
-**Value Range** Array of [EnumRegionPredetectionMode](../enum/EnumRegionPredetectionMode.md) items.
-
-**Default Value** `[RPM_GENERAL,RPM_SKIP,RPM_SKIP,RPM_SKIP,RPM_SKIP,RPM_SKIP,RPM_SKIP,RPM_SKIP]`
-
-**Remarks** If the image is large, and the barcode is very small relative to the whole image, then it is recommended to enable region predetction to speed up the localization process and recognition accuracy.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.regionPredetectionModes[0] = Dynamsoft.DBR.EnumRegionPredetectionMode.RPM_GENERAL_RGB_CONTRAST;
-runtimeSettings.furtherModes.regionPredetectionModes[1] = Dynamsoft.DBR.EnumRegionPredetectionMode.RPM_GENERAL;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### imagePreprocessingModes
-
-This parameter helps enhance or keep the features of barcode zones by processing colour or grayscale images, in turn improving the localization process.
-
-**Value Range** Array of [EnumImagePreprocessingMode](../enum/EnumImagePreprocessingMode.md) items.
-
-**Default Value** `[IPM_GENERAL,IPM_SKIP,IPM_SKIP,IPM_SKIP,IPM_SKIP,IPM_SKIP,IPM_SKIP,IPM_SKIP]`
-
-**Remarks** In order for barcodes to be localized, the barcode must have clear barcode zone features that the algorithm uses to find the barcode and in turn recognize it. By enhancing some of the available zone features, the process of finding the barcode can also potentially become more effective.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.imagePreprocessingModes[0] = Dynamsoft.DBR.EnumImagePreprocessingMode.IPM_GRAY_SMOOTH;
-runtimeSettings.furtherModes.imagePreprocessingModes[1] = Dynamsoft.DBR.EnumImagePreprocessingMode.IPM_SHARPEN_SMOOTH;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### textureDetectionModes
-
-When scanning 1D barcodes, this parameter helps reduce the time cost and error probability caused by textures that can resemble 1D barcodes.
-
-**Value Range** Array of [EnumTextureDetectionMode](../enum/EnumTextureDetectionMode.md) items.
-
-**Default Value** `[TDM_GENERAL_WIDTH_CONCENTRATION,TDM_SKIP,TDM_SKIP,TDM_SKIP,TDM_SKIP,TDM_SKIP,TDM_SKIP,TDM_SKIP]`
-
-**Remarks** Mainly applicable when scanning 1D barcodes.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.textureDetectionModes[0] = Dynamsoft.DBR.EnumTextureDetectionMode.TDM_SKIP; // to disable this parameter completely
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### dpmCodeReadingModes
-
-This parameter should only be enabled when working with DPM codes. By default, DPM reading is disabled.
-
-**Value Range** Array of [EnumDPMCodeReadingMode](../enum/EnumDPMCodeReadingMode.md) items
-
-**Default Value** `[DPMCRM_SKIP,DPMCRM_SKIP,DPMCRM_SKIP,DPMCRM_SKIP,DPMCRM_SKIP,DPMCRM_SKIP,DPMCRM_SKIP,DPMCRM_SKIP]`
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.dpmCodeReadingModes[0] = Dynamsoft.DBR.EnumDPMCodeReadingMode.DPMCRM_GENERAL; // to enable DPM code reading set the highest priority item to General
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### deformationResistingModes
-
-This parameter should be used when handling distorted or deformed barcodes. Currently, there is only one general mode that deal with the deformation resistance, so if you are looking to enable this feature, then please refer to the code snippet.
-
-**Value Range** Array of [EnumDeformationResistingMode](../enum/EnumDeformationResistingMode.md) items
-
-**Default Value** `[DRM_SKIP,DRM_SKIP,DRM_SKIP,DRM_SKIP,DRM_SKIP,DRM_SKIP,DRM_SKIP,DRM_SKIP]`
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.deformationResistingModes[0] = Dynamsoft.DBR.EnumDeformationResistingMode.DRM_GENERAL; // to enable deformation resistance set the highest priority item to General
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### barcodeComplementModes
-
-When dealing with a barcode that has 'missing' parts, this parameter controls how to complement the missing parts of said barcode.
-
-**Value Range** Array of [EnumBarcodeComplementMode](../enum/EnumBarcodeComplementMode.md) items
-
-**Default Value** `[BCM_SKIP,BCM_SKIP,BCM_SKIP,BCM_SKIP,BCM_SKIP,BCM_SKIP,BCM_SKIP,BCM_SKIP]`
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.barcodeComplementModes[0] = Dynamsoft.DBR.EnumBarcodeComplementMode.BCM_GENERAL; // to enable the barcode complement feature set the highest priority item to General
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### barcodeColourModes
-
-**Please note that this API is not yet applicable. Please use [grayscaleTransformationModes](#grayscaletransformationmodes) instead.**
-
-In most cases, barcodes come as a dark image with a light background (e.g. black barcode on a white background). However, that is not always the case as the barcodes can come as a light image with a dark background, or some other variation.
-
-**Value Range** Array of [EnumBarcodeColourMode](../enum/EnumBarcodeColourMode.md) items
-
-**Default Value** `[BICM_DARK_ON_LIGHT,BICM_SKIP,BICM_SKIP,BICM_SKIP,BICM_SKIP,BICM_SKIP,BICM_SKIP,BICM_SKIP]`

-**Remarks** To learn about the purpose of each mode, please refer to this [page](https://www.dynamsoft.com/barcode-reader/parameters/reference/barcode-colour-modes.html?ver=latest).
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.furtherModes.barcodeColourModes[0] = Dynamsoft.DBR.EnumBarcodeColourMode.BICM_DARK_ON_LIGHT; // to support both dark-on-light and light-on-dark barcodes then the array must contain both modes.
-runtimeSettings.furtherModes.barcodeColourModes[1] = Dynamsoft.DBR.EnumBarcodeColourMode.BICM_LIGHT_ON_DARK; // to support both dark-on-light and light-on-dark barcodes then the array must contain both modes.

-
-**Default Value** `BF_ALL`
-
-**Remarks** If the barcode type(s) are certain, specifying the barcode type(s) to be read will speed up the recognition process. If you are looking to set a barcode format that is included in the second group, please refer to barcodeFormatIds_2.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### barcodeFormatIds_2
-
-Sets the formats of the barcode in BarcodeFormat group 2 to be read. Barcode formats in BarcodeFormat group 1 can be combined.
-
-**Value Range** A combined value of the [EnumBarcodeFormat_2](../enum/EnumBarcodeFormat_2.md) items.
-
-**Default Value** `BF2_NULL`
-
-**Remarks** If the barcode type(s) are certain, specifying the barcode type(s) to be read will speed up the recognition process.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds_2 = Dynamsoft.DBR.EnumBarcodeFormat_2.BF2_POSTALCODE | Dynamsoft.DBR.EnumBarcodeFormat_2.BF2_POSTNET;

-
-**Remarks** The following explains the value:
-
-* 0: means Unknown and it will return the result of the first successful [localization mode](../enum/EnumLocalizationMode.md) attempt.
-* 1: try to find one barcode. If one barcode is found, the library will stop the localization process and perform barcode decoding.
-* n: try to find n barcodes. If the library only finds m (m < n) barcode, it will try different algorithms till n barcodes are found or all algorithms are tried.
-

-**Remarks** If the shortest edge size is larger than the given threshold value, the library will calculate the required height and width of the barcode image and shrink the image to that size before localization. Otherwise, the library will perform barcode localization on the original image.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.scaleDownThreshold = 1000;
-await reader.updateRuntimeSettings(runtimeSettings);
-```

-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.binarizationModes[0] = Dynamsoft.DBR.EnumBinarizationMode.BM_SKIP;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### region
-
-Sets the [Region](Region.md) including the regionTop, regionLeft, regionRight, regionBottom and regionMeasuredByPercentage. To learn more about how the region parameters work, please refer to the [Region section of the Parameters Template](https://www.dynamsoft.com/barcode-reader/docs/core/parameters/structure-and-interfaces-of-parameters.html?ver=latest#regiondefinition-and-how-it-works)

-
-> Experimental feature:
->
-> When using the  [BarcodeScanner](../BarcodeScanner.md) class, `region` can be an array. For example `region = [r0, r1, r2]`, 0th frame use `r0`, 1st use `r1`, 2nd use `r2`, 3rd use `r0`, and then loop like this.
->
-> ```js
-> let runtimeSettings = await reader.getRuntimeSettings();
-> runtimeSettings.region = [
->   null, // full image
->   {regionLeft:25,regionTop:25,regionRight:75,regionBottom:75,regionMeasuredByPercentage:true}, // center 50% 
->   {regionLeft:5,regionTop:45,regionRight:95,regionBottom:55,regionMeasuredByPercentage:true}, // width 90%, height 10% 
-> ];
-> await reader.updateRuntimeSettings(runtimeSettings);
-> ```
-

-**Value Range** [0, 0x7fffffff]
-
-**Default Value** 30
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();

-**Remarks** When decoding barcodes from a PDF file using the DecodeFile method, the library will convert the PDF file to image(s) first, then perform barcode recognition.
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.pdfRasterDPI = 100;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### pdfReadingMode
-
-Sets the way to detect barcodes from a PDF file when using the DecodeFile method.
-
-**Value Range** Any one of the [EnumPDFReadingMode](../enum/EnumPDFReadingMode.md) Enumeration items. 
-
-**Default Value** `PDFRM_AUTO`  
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.pdfReadingMode = Dynamsoft.DBR.EnumPDFReadingMode.PDFRM_VECTOR;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
--->
-### returnBarcodeZoneClarity
-
-Sets whether or not to return the clarity of the barcode zone.
-
-**Value Range** [0,1]
-
-**Default Value** 0
-
-**Remarks** 0: Do not return the clarity of the barcode zone; 1: Return the clarity of the barcode zone. 
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.returnBarcodeZoneClarity = 1;
-await reader.updateRuntimeSettings(runtimeSettings);
-```
-
-### textResultOrderModes
-
-Sets the mode and priority for the order of the text results returned.
-
-**Value Range** Each array item can be any one of the [EnumTextResultOrderMode](../enum/EnumTextResultOrderMode.md) Enumeration items.
-
-**Default Value** `[TROM_CONFIDENCE, TROM_POSITION, TROM_FORMAT, TROM_SKIP, TROM_SKIP, TROM_SKIP, TROM_SKIP, TROM_SKIP]`
-
-**Remarks** The array index represents the priority of the item. The smaller the index, the higher the priority.   
-
-```js
-let runtimeSettings = await reader.getRuntimeSettings();
-runtimeSettings.textResultOrderModes[0] = Dynamsoft.DBR.TextResultOrderMode.TROM_POSITION; // sets the highest priority item to TROM_POSITION
-await reader.updateRuntimeSettings(runtimeSettings);

-# Dynamsoft Barcode Reader JavaScript Edition - Introduction
-
-This version of Dynamsoft Barcode Reader (hereinafter referred to as "the library") is based on JavaScript and WebAssembly and can run in all major modern browsers on all major platforms. It is ideal for 
-
-* Organizations who already have sophisticated websites and do not intend to develop mobile applications for the same purposes;
-* Organizations whose customers have no desire to install applications for temporary usage of their services.
-
-## Fast Integration
-
-With the library integrated, end users can open the web page in a browser, access their cameras and read barcodes directly from the video input. The integration can be done with just a few lines of code and without the hassle of installing anything.
-
-``` html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.5/dist/dbr.js"></script>
-<script>
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    scanner.onUnduplicatedRead = (txt, result) => {
-        // Do somthing with the "txt" found in the barcode
-    };
-    await scanner.show();
-</script>
-```
-
-The above lines of code has completed the integration of the library into a web page and this is made possible with the following two features.
-
-### Built-in Camera Control
-
-Customers generally need to scan a barcode on the fly at which time there is no better input than the camera hooked to or built into the device itself. The library uses the powerful **MediaDevices** interface (provided by the browser itself) to instantly connect the video input of the camera with the back-end decoding engine.
-
-### Interactive UI
-
-Good interaction design is essential for a website, the same is true for SDKs such as the library. As shown in the screenshot below, the library streams the video on the page, guides the user where to aim and highlights the areas where barcodes are found.
-
-![Interactive UI](assets/interactive-ui.png)
-
-> NOTE: 
-> 
-> When the client opens the page, the library is immediately initialized in the background, which takes a few seconds to complete. By the time the customer is asked to scan a barcode, the library will already be ready.
-
-## High Performance
-
-Barcode reading is usually just an auxiliary way to assist a small step in a complex workflow. Customers like the convenience, but if it takes too long or is error-prone, their patience will quickly run out. Therefore, high performance is crucial.
-
-### Unparalleled Speed
-
-The library showcases Dynamsoft's cutting-edge technology in light-speed recognition of barcodes. In most cases, an image gets deblurred, binarized and read under 100 milliseconds. 
-
-<!--TODO
-
-add more info (APIs, etc.) on how we achieve better speed
-
--->
-
-### Proficiency in Handling Difficult Environments
-
-The actual use environment is unpredictable. The barcode may appear distorted, inverted, or partially damaged; the background may be textured or spotted; the light may be very low, and there may be shadows and glare. The library handles all these cases with its rich image processing algorithms through various adjustable settings.
-
-<!--TODO
-
-add more info (APIs, etc.) on how we handle these tough codes
-
--->
-
-### Exceptional Accuracy
-
-The library does a lot of preparation work to make sure the barcode is as legible as possible for the decoding engine to read. This ensures a very high accuracy. In addition, the library achieves even higher accuracy through the following ways:
-
-* The library has a confidence score for each recognition which can be used to filter unwanted results;
-* In the case of continuous scanning, the library compares the results of multiple consecutive recognitions and return only the results confirmed by at least two efforts.
-
-Through many experiences, the library has also cultivated its error correction ability against barcodes which do not strictly abide by the specification as well as deformed barcodes caused by improper printing.
-
-## Usage Scenarios
-
-The library is designed for websites. Common usage scenarios include:
-
-### Retail
-
-Most if not all products on the market now have barcodes on their packaging. Customers can scan the barcode to place an order, register a product for post-sales service or just trace the product to its origin.
-
-### ID Scanning
-
-All driver's licenses issued in the USA and Canada by the American Association of Motor Vehicle Administrators (AAMVA) have a PDF417 Barcode on them. The information encoded in the Barcode follows the DL/ID Card Design Standard (CDS) and can be easily parsed to meaningful form fields.
-
-Other ID cards that come with barcodes include the Permanent Account Number (PAN) Card in India, Driver's license in South Africa, etc.
-
-### VIN Scanning
-
-Every vehicle has its own Vehicle Identification Number (VIN). When printing the number on the vehicle, many manufacturers also print a barcode alongside it. Customers can scan the barcode to register for an insurance claim or look up vehicle information like maintenance records, mileage rollbacks, etc.
-
-### Inventory Management
-
-Inventory management is a highly stressful and arduous process where both efficiency and accuracy are crucial. Customers can use the library to scan multiple items at the same time which greatly boosts efficiency.

-# Dynamsoft Barcode Reader JavaScript Edition - Introduction
-
-This version of Dynamsoft Barcode Reader (hereinafter referred to as "the library") is based on JavaScript and WebAssembly and can run in all major modern browsers on all major platforms. It is ideal for 
-
-* Organizations who already have sophisticated websites and do not intend to develop mobile applications for the same purposes;
-* Organizations whose customers have no desire to install applications for temporary usage of their services.
-
-## Fast Integration
-
-With the library integrated, end users can open the web page in a browser, access their cameras and read barcodes directly from the video input. The integration can be done with just a few lines of code and without the hassle of installing anything.
-
-``` html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.4.0/dist/dbr.js"></script>
-<script>
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    scanner.onUnduplicatedRead = (txt, result) => {
-        // Do somthing with the "txt" found in the barcode
-    };
-    await scanner.show();
-</script>
-```
-
-The above lines of code has completed the integration of the library into a web page and this is made possible with the following two features.
-
-### Built-in Camera Control
-
-Customers generally need to scan a barcode on the fly at which time there is no better input than the camera hooked to or built into the device itself. The library uses the powerful **MediaDevices** interface (provided by the browser itself) to instantly connect the video input of the camera with the back-end decoding engine.
-
-### Interactive UI
-
-Good interaction design is essential for a website, the same is true for SDKs such as the library. As shown in the screenshot below, the library streams the video on the page, guides the user where to aim and highlights the areas where barcodes are found.
-
-![Interactive UI](assets/interactive-ui.png)
-
-> NOTE: 
-> 
-> When the client opens the page, the library is immediately initialized in the background, which takes a few seconds to complete. By the time the customer is asked to scan a barcode, the library will already be ready.
-
-## High Performance
-
-Barcode reading is usually just an auxiliary way to assist a small step in a complex workflow. Customers like the convenience, but if it takes too long or is error-prone, their patience will quickly run out. Therefore, high performance is crucial.
-
-### Unparalleled Speed
-
-The library showcases Dynamsoft's cutting-edge technology in light-speed recognition of barcodes. In most cases, an image gets deblurred, binarized and read under 100 milliseconds. 
-
-<!--TODO
-
-add more info (APIs, etc.) on how we achieve better speed
-
--->
-
-### Proficiency in Handling Difficult Environments
-
-The actual use environment is unpredictable. The barcode may appear distorted, inverted, or partially damaged; the background may be textured or spotted; the light may be very low, and there may be shadows and glare. The library handles all these cases with its rich image processing algorithms through various adjustable settings.
-
-<!--TODO
-
-add more info (APIs, etc.) on how we handle these tough codes
-
--->
-
-### Exceptional Accuracy
-
-The library does a lot of preparation work to make sure the barcode is as legible as possible for the decoding engine to read. This ensures a very high accuracy. In addition, the library achieves even higher accuracy through the following ways:
-
-* The library has a confidence score for each recognition which can be used to filter unwanted results;
-* In the case of continuous scanning, the library compares the results of multiple consecutive recognitions and return only the results confirmed by at least two efforts.
-
-Through many experiences, the library has also cultivated its error correction ability against barcodes which do not strictly abide by the specification as well as deformed barcodes caused by improper printing.
-
-## Usage Scenarios
-
-The library is designed for websites. Common usage scenarios include:
-
-### Retail
-
-Most if not all products on the market now have barcodes on their packaging. Customers can scan the barcode to place an order, register a product for post-sales service or just trace the product to its origin.
-
-### ID Scanning
-
-All driver's licenses issued in the USA and Canada by the American Association of Motor Vehicle Administrators (AAMVA) have a PDF417 Barcode on them. The information encoded in the Barcode follows the DL/ID Card Design Standard (CDS) and can be easily parsed to meaningful form fields.
-
-Other ID cards that come with barcodes include the Permanent Account Number (PAN) Card in India, Driver's license in South Africa, etc.
-
-### VIN Scanning
-
-Every vehicle has its own Vehicle Identification Number (VIN). When printing the number on the vehicle, many manufacturers also print a barcode alongside it. Customers can scan the barcode to register for an insurance claim or look up vehicle information like maintenance records, mileage rollbacks, etc.
-
-### Inventory Management
-
-Inventory management is a highly stressful and arduous process where both efficiency and accuracy are crucial. Customers can use the library to scan multiple items at the same time which greatly boosts efficiency.

-Barcode reading is usually just an auxiliary way to assist a small step in a complex workflow. Customers like the convenience, but if it takes too long or is error-prone, their patience will quickly run out. Therefore, high performance is crucial.
-
-### Unparalleled Speed
-
-The library showcases Dynamsoft's cutting-edge technology in light-speed recognition of barcodes. In most cases, an image gets deblurred, binarized and read under 100 milliseconds. 
-
-<!--TODO
-
-add more info (APIs, etc.) on how we achieve better speed
-
--->
-
-### Proficiency in Handling Difficult Environments
-
-The actual use environment is unpredictable. The barcode may appear distorted, inverted, or partially damaged; the background may be textured or spotted; the light may be very low, and there may be shadows and glare. The library handles all these cases with its rich image processing algorithms through various adjustable settings.
-
-<!--TODO
-
-add more info (APIs, etc.) on how we handle these tough codes
-
--->
-
-### Exceptional Accuracy
-
-The library does a lot of preparation work to make sure the barcode is as legible as possible for the decoding engine to read. This ensures a very high accuracy. In addition, the library achieves even higher accuracy through the following ways:
-
-* The library has a confidence score for each recognition which can be used to filter unwanted results;
-* In the case of continuous scanning, the library compares the results of multiple consecutive recognitions and return only the results confirmed by at least two efforts.
-
-Through many experiences, the library has also cultivated its error correction ability against barcodes which do not strictly abide by the specification as well as deformed barcodes caused by improper printing.
-
-## Usage Scenarios
-
-The library is designed for websites. Common usage scenarios include:
-
-### Retail
-
-Most if not all products on the market now have barcodes on their packaging. Customers can scan the barcode to place an order, register a product for post-sales service or just trace the product to its origin.
-
-### ID Scanning
-
-All driver's licenses issued in the USA and Canada by the American Association of Motor Vehicle Administrators (AAMVA) have a PDF417 Barcode on them. The information encoded in the Barcode follows the DL/ID Card Design Standard (CDS) and can be easily parsed to meaningful form fields.
-
-Other ID cards that come with barcodes include the Permanent Account Number (PAN) Card in India, Driver's license in South Africa, etc.
-
-### VIN Scanning
-
-Every vehicle has its own Vehicle Identification Number (VIN). When printing the number on the vehicle, many manufacturers also print a barcode alongside it. Customers can scan the barcode to register for an insurance claim or look up vehicle information like maintenance records, mileage rollbacks, etc.
-
-### Inventory Management
-
-Inventory management is a highly stressful and arduous process where both efficiency and accuracy are crucial. Customers can use the library to scan multiple items at the same time which greatly boosts efficiency.

-# Dynamsoft Barcode Reader JavaScript Edition - Introduction
-
-This version of Dynamsoft Barcode Reader (hereinafter referred to as "the library") is based on JavaScript and WebAssembly and can run in all major modern browsers on all major platforms. It is ideal for 
-
-* Organizations who already have sophisticated websites and do not intend to develop mobile applications for the same purposes;
-* Organizations whose customers have no desire to install applications for temporary usage of their services.
-
-## Fast Integration
-
-With the library integrated, end users can open the web page in a browser, access their cameras and read barcodes directly from the video input. The integration can be done with just a few lines of code and without the hassle of installing anything.
-
-``` html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.5/dist/dbr.js"></script>
-<script>
-    (async()=>{
-        let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-        scanner.onUnduplicatedRead = (txt, result) => {
-        // Do somthing with the "txt" found in the barcode
-        };
-        await scanner.show();
-    })();
-</script>
-```
-
-The above lines of code has completed the integration of the library into a web page and this is made possible with the following two features.
-
-### Built-in Camera Control
-
-Customers generally need to scan a barcode on the fly at which time there is no better input than the camera hooked to or built into the device itself. The library uses the powerful **MediaDevices** interface (provided by the browser itself) to instantly connect the video input of the camera with the back-end decoding engine.
-
-### Interactive UI
-
-Good interaction design is essential for a website, the same is true for SDKs such as the library. As shown in the screenshot below, the library streams the video on the page, guides the user where to aim and highlights the areas where barcodes are found.
-
-![Interactive UI](assets/interactive-ui.png)
-
-> NOTE: 
-> 
-> When the client opens the page, the library is immediately initialized in the background, which takes a few seconds to complete. By the time the customer is asked to scan a barcode, the library will already be ready.

-# Dynamsoft Barcode Reader JavaScript Edition
-
-Dynamsoft Barcode Reader (DBR) can be used in JavaScript to add barcode reading capabilities to websites running in modern browsers. It is ideal for
-
-* Organizations who already have sophisticated websites and do not intend to develop mobile applications for the same purposes;
-* Organizations whose customers have no desire to install applications for temporary usage of their services.
-
-To get a fast start, you can
-
-* Read the [User Guide](user-guide/)
-* Try the [Samples and Demos](samples-demos/)
-
-The following describes the highlights of DBR when used in JavaScript.
-
-## Fast Integration
-
-The following lines of code is all that is required to integrate DBR in JavaScript:
-
-``` html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.2/dist/dbr.js"></script>
-<script>
-  // specify a license, you can visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=intro&product=dbr&package=js to get your own trial license good for 30 days. 
-  Dynamsoft.DBR.BarcodeScanner.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-  (async()=>{
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    scanner.onUniqueRead = (txt, result) => {
-      // Do something with the "txt" found in the barcode
-    };
-    await scanner.show();
-  })();
-</script>
-```
-
-After the integration, end users of the web page can open it in a browser, access their cameras and read barcodes directly from the video input.
-
-### Built-in Camera Control
-
-Customers generally need to scan a barcode on the fly at which time there is no better input than the camera hooked to or built into the device itself. DBR uses the powerful **MediaDevices** interface (provided by the browser itself) to instantly connect the video input of the camera with the back-end decoding engine.
-
-### Interactive UI
-
-Good interaction design is essential for a website, the same is true for SDKs such as DBR. As shown in the screenshot below, DBR streams the video on the page, guides the user where to aim and highlights the areas where barcodes are found.
-
-![Interactive UI](assets/interactive-ui.png)
-
-## High Performance
-
-Barcode reading is usually just an auxiliary way to assist a small step in a complex workflow. Customers like the convenience, but if it takes too long or is error-prone, their patience will quickly run out. Therefore, high performance is crucial.
-
-### Unparalleled Speed
-
-DBR showcases Dynamsoft's cutting-edge technology in light-speed recognition of barcodes. In most cases, an image gets deblurred, binarized and read under 100 milliseconds.
-
-### Proficiency in Handling Difficult Environments
-
-The actual use environment is unpredictable. The barcode may appear distorted, inverted, or partially damaged; the background may be textured or spotted; the light may be very low, and there may be shadows and glare. DBR handles all these cases with its rich image processing algorithms through various adjustable settings.
-
-### Exceptional Accuracy
-
-DBR does a lot of preparation work to make sure the barcode is as legible as possible for the decoding engine to read. This ensures a very high accuracy. In addition, DBR achieves even higher accuracy through the following ways:
-
-* DBR has a confidence score for each recognition which can be used to filter unwanted results;
-* In the case of continuous scanning, DBR compares the results of multiple consecutive recognitions and return only the results confirmed by at least two efforts.
-
-Through many experiences, DBR has also cultivated its error correction ability against barcodes which do not strictly abide by the specification as well as deformed barcodes caused by improper printing.
-
-## Next Step
-
-Read the [User Guide](user-guide/) to start buidling your own websites with barcode reading capabilities.

-# Dynamsoft Barcode Reader JavaScript Edition
-
-Dynamsoft Barcode Reader (DBR) can be used in JavaScript to add barcode reading capabilities to websites running in modern browsers. It is ideal for
-
-* Organizations who already have sophisticated websites and do not intend to develop mobile applications for the same purposes;
-* Organizations whose customers have no desire to install applications for temporary usage of their services.
-
-To get a fast start, you can
-
-* Read the [User Guide](user-guide/)
-* Try the [Samples and Demos](samples-demos/)
-
-The following describes the highlights of DBR when used in JavaScript.
-
-## Fast Integration
-
-The following lines of code is all that is required to integrate DBR in JavaScript:
-
-``` html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.40/dist/dbr.js"></script>
-<script>
-  // specify a license, you can visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=intro&product=dbr&package=js to get your own trial license good for 30 days. 
-  Dynamsoft.DBR.BarcodeScanner.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-  (async()=>{
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    scanner.onUniqueRead = (txt, result) => {
-      // Do something with the "txt" found in the barcode
-    };
-    await scanner.show();
-  })();
-</script>
-```
-
-After the integration, end users of the web page can open it in a browser, access their cameras and read barcodes directly from the video input.
-
-### Built-in Camera Control
-
-Customers generally need to scan a barcode on the fly at which time there is no better input than the camera hooked to or built into the device itself. DBR uses the powerful **MediaDevices** interface (provided by the browser itself) to instantly connect the video input of the camera with the back-end decoding engine.
-
-### Interactive UI
-
-Good interaction design is essential for a website, the same is true for SDKs such as DBR. As shown in the screenshot below, DBR streams the video on the page, guides the user where to aim and highlights the areas where barcodes are found.
-
-![Interactive UI](assets/interactive-ui.png)
-
-## High Performance
-
-Barcode reading is usually just an auxiliary way to assist a small step in a complex workflow. Customers like the convenience, but if it takes too long or is error-prone, their patience will quickly run out. Therefore, high performance is crucial.
-
-### Unparalleled Speed
-
-DBR showcases Dynamsoft's cutting-edge technology in light-speed recognition of barcodes. In most cases, an image gets deblurred, binarized and read under 100 milliseconds.
-
-### Proficiency in Handling Difficult Environments
-
-The actual use environment is unpredictable. The barcode may appear distorted, inverted, or partially damaged; the background may be textured or spotted; the light may be very low, and there may be shadows and glare. DBR handles all these cases with its rich image processing algorithms through various adjustable settings.
-
-### Exceptional Accuracy
-
-DBR does a lot of preparation work to make sure the barcode is as legible as possible for the decoding engine to read. This ensures a very high accuracy. In addition, DBR achieves even higher accuracy through the following ways:
-
-* DBR has a confidence score for each recognition which can be used to filter unwanted results;
-* In the case of continuous scanning, DBR compares the results of multiple consecutive recognitions and return only the results confirmed by at least two efforts.
-
-Through many experiences, DBR has also cultivated its error correction ability against barcodes which do not strictly abide by the specification as well as deformed barcodes caused by improper printing.
-
-## Next Step
-
-Read the [User Guide](user-guide/) to start building your own websites with barcode reading capabilities.

-# Debug Sample
-
-This sample is designed to:
-
-1. Print detailed logs in the browser console to better assist in troubleshooting.
-2. Check if your device and browser are compatible with the camera and to what extent.
-3. Collect video frames for analysis. (Require to host the sample locally)
-
-## Collect the video frames for analysis
-
-Barcode reading is a one-time job, the application either succeeds or fails to read the barcode(s). For the failed scenario, it's possible to make them successful by adjusting the settings provided by the Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library"). However, adjusting the settings could be a bit overwhelming. Therefore, Dynamsoft offers the debug sample that enables customers to capture and save runtime video frames for sending to the Dynamsoft team. With the original images, the team can test and optimize settings for customers.
-
-The following shows how to host the sample and collect frames.
-
-### Download the sample
-
-The sample can be downloaded from
-
-<a target_="blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/5.others/debug" alt="Debug Sample on GitHub">Debug Sample on GitHub</a>
-
-Note that the entire folder is required. To download only the files in this folder, try using "https://downgit.github.io/#/home".
-
-### Set up a local server
-
-Since the video is usually playing on mobile devices, having these frames uploaded to a self-hosted local server is most convenient, therefore, we first need to set up a local server.
-
-We make use of the web server that comes with [Express](https://expressjs.com/).
-
-* Install dependencies
-
-Run the following script to install all dependencies.
-
-`npm install`
-
-* Start the server
-
-We defined the web server logic in the file "app.js", to start it, run the following script:
-
-`node app.js`
-
-Note that we have used self-signed certificates to enable SSL on the port 4443.
-
-### Use the sample page
-
-Once the server is up and running, open the page on the device that will do the barcode reading. The URL for the sample is "https://{your-local-ip}:4443/". For example, suppose your ip is 192.168.1.1, the site can be visited at "https://192.168.1.1:4443/".
-
-> Note that the device should be in the same WiFi network as the server machine. 
-
-You will see a warning due to self-signing. Please ignore and keep processing.
-
-Click the button "show scanner" and try to read barcodes, the frames will then be uploaded to the folder "debug\public\collect" as images (.png) on the server. When you have collected enough frames, please turn off the scanner, otherwise, new frames will continue to flood in.
-
-Check the images to make sure that they correctly represent the actual usage scenario, then zip and send them to Dynamsoft for technical assistance.

-# Hello-world for Angular - Dynamsoft Barcode Reader Sample
-
-[Angular](https://angular.io/) is one of the most popular and mature JavaScript frameworks. Check out the following on how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into an Angular application.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/3.read-video-angular">Hello World in Angular - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) and [Angular CLI](https://cli.angular.io/) installed. `node 14.21.3` and `Angular CLI 15.2.1` are used in the example below.
-
-## Create the sample project
-
-### Create an out-of-the-box raw Angular application 
-
-```cmd
-ng new read-video-angular
-```
-
-### **CD** to the root directory of the application and install the library
-
-```cmd
-cd read-video-angular
-npm install dynamsoft-javascript-barcode
-```
-
-## Start to implement
-
-### Add a file "dbr.ts" under "src/app/" to configure the library
-
-```typescript
-import { BarcodeReader } from 'dynamsoft-javascript-barcode';
-BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```
-
-> Note:
->
-> * `license` specify a license key to use the library. You can visit [https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js) to get your own trial license good for 30 days. 
-> * `engineResourcePath` tells the library where to get the necessary resources at runtime.
-
-### Generate three components
-* `video-decode` component help read barcode from camera.
-```cmd
-ng generate component video-decode
-```
-* `img-decode` component help read barcode from still images.
-```cmd
-ng generate component img-decode
-```
-* `hello-world` component offers buttons to switch components above.
-```cmd
-ng generate component hello-world
-```
-
-### Edit the video-decode component
-
-* There is a default UI in `.\node_modules\dynamsoft-javascript-barcode\dist\dbr.ui.html`, which we will use in this sample. Copy everything in this file and replace the original code in `video-decode.component.html`. If you want to customize the UI, see more in `2.ui-tweaking` or [User Guide](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/customize-the-ui.html?lang=js).
-
-* In `video-decode.component.ts`, add code for initializing and destroying the `BarcodeScanner` instance.
-
-```typescript
-import { Component, OnInit } from '@angular/core';
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-@Component({
-  selector: 'app-video-decode',
-  templateUrl: './video-decode.component.html',
-  styleUrls: ['./video-decode.component.css'],
-})
-export class VideoDecodeComponent implements OnInit {
-  pScanner: Promise<BarcodeScanner> | null = null;
-
-  async ngOnInit(): Promise<void> {
-    try {
-      const scanner = await (this.pScanner = BarcodeScanner.createInstance());
-      await scanner.setUIElement(
-        (document.querySelector('.dce-video-container') as HTMLElement).parentElement as HTMLElement
-      );
-      scanner.onFrameRead = (results: any) => {
-        for (const result of results) {
-          console.log(result.barcodeText);
-        }
-      };
-      scanner.onUniqueRead = (txt, result) => {
-        alert(txt);
-      };
-      await scanner.open();
-    } catch (ex: any) {
-      let errMsg;
-      if (ex.message.includes('network connection error')) {
-        errMsg =
-          'Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.';
-      } else {
-        errMsg = ex.message || ex;
-      }
-      console.error(errMsg);
-      alert(errMsg);
-    }
-  }
-  async ngOnDestroy() {
-    if (this.pScanner) {
-      (await this.pScanner).destroyContext();
-      console.log('BarcodeScanner Component Unmount');
-    }
-  }
-}
-```
-
-> Note:
->
-> * The method `createInstance()` is called to initialize the library as soon as the component initializes.
-> * To release resources timely, the `BarcodeScanner` instance is destroyed with the component in the callback `ngOnDestroy` .
-> * The `setUIElement()` method is used to define the user interface (UI) for the library using the native element in `video-decode.component.html`, which was copied in the previous step.
-
-### Edit the img-decode component
-
-* Replace the original code in `img-decode.component.html` with code below to select a local image via `input` element.
-
-```html
-<div class="ImgDecode"><input type="file" (change)="decodeImg($event)"/></div>
-```
-
-* Add CSS style in `img-decode.component.css`.
-
-```css
-.ImgDecode {
-  display: flex;
-  justify-content: center;
-  align-items: center;
-  width: 100%;
-  border: 1px solid black
-}
-```
-
-* In `img-decode.component.ts`, add code for initializing and destroying the `BarcodeReader` instance.
-
-```typescript
-import { Component, OnInit } from '@angular/core';
-import { BarcodeReader } from 'dynamsoft-javascript-barcode'
-
-@Component({
-  selector: 'app-img-decode',
-  templateUrl: './img-decode.component.html',
-  styleUrls: ['./img-decode.component.css']
-})
-export class ImgDecodeComponent implements OnInit {
-  pReader: Promise<BarcodeReader> | null = null;
-
-  async ngOnInit(): Promise<void> { }
-
-  decodeImg = async (e: any) => {
-    try {
-      const reader = await (this.pReader = this.pReader || BarcodeReader.createInstance());
-      const results = await reader.decode(e.target.files[0]);
-      for (const result of results) {
-        alert(result.barcodeText);
-      }
-      if (!results.length) { alert('No barcode found'); }
-    } catch (ex: any) {
-      let errMsg;
-      if (ex.message.includes("network connection error")) {
-        errMsg = "Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.";
-      } else {
-        errMsg = ex.message||ex;
-      }
-      console.error(errMsg);
-      alert(errMsg);
-    }
-    e.target.value = '';
-  }
-
-  async ngOnDestroy() {
-    if (this.pReader) {
-      (await this.pReader).destroyContext();
-      console.log('ImgDecode Component Unmount');
-    }
-  }
-}
-```
-
-> Note:
->
-> * The method `createInstance()` is called to initialize the library as soon as the component initializes.
-> * To release resources timely, the `BarcodeReader` instance is destroyed with the component in the callback `ngOnDestroy` .
-
-### Edit the hello-world component
-
-* Use the components in `hello-world.component.html`.
-
-```html
-<div class="helloWorld">
-    <h1>Hello World for Angular<img style="height: 25px;" alt="logo" src="data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZpZXdCb3g9IjAgMCAyNTAgMjUwIj4KICAgIDxwYXRoIGZpbGw9IiNERDAwMzEiIGQ9Ik0xMjUgMzBMMzEuOSA2My4ybDE0LjIgMTIzLjFMMTI1IDIzMGw3OC45LTQzLjcgMTQuMi0xMjMuMXoiIC8+CiAgICA8cGF0aCBmaWxsPSIjQzMwMDJGIiBkPSJNMTI1IDMwdjIyLjItLjFWMjMwbDc4LjktNDMuNyAxNC4yLTEyMy4xTDEyNSAzMHoiIC8+CiAgICA8cGF0aCAgZmlsbD0iI0ZGRkZGRiIgZD0iTTEyNSA1Mi4xTDY2LjggMTgyLjZoMjEuN2wxMS43LTI5LjJoNDkuNGwxMS43IDI5LjJIMTgzTDEyNSA1Mi4xem0xNyA4My4zaC0zNGwxNy00MC45IDE3IDQwLjl6IiAvPgogIDwvc3ZnPg=="

-    <div>
-        <button [ngStyle]="{'margin-right': '10px', 'background-color': bShowScanner ? 'rgb(255,174,55)' : 'white'}" (click)="showScanner()">Video Decode</button>
-        <button [ngStyle]="{'background-color': !bShowScanner ? 'rgb(255,174,55)' : 'white'}" (click)="showImgDecode()">Image Decode</button>
-    </div>
-    <div class="container">

-        <app-img-decode *ngIf="bShowImgDecode"></app-img-decode>
-    </div>
-</div>
-```
-
-* Define the style of the element in `hello-world.component.css`.
-
-```css
-.helloWorld {
-  display: flex;
-  flex-direction: column;
-  align-items: center;
-  justify-content: center;
-  width: 100%;
-  height: 100%;
-  color: #455A64;
-}
-
-button {
-  font-size: 1.5rem;
-  margin: 1.5vh 0;
-  border: 1px solid black;
-  background-color: white;
-  color: black;
-}
-
-.container {
-  margin: 2vmin auto;
-  height: 70vh;
-  width: 80vw;
-}
-
-h1 {
-  font-size: 1.5em;
-}
-```
-
-* Add following code to `hello-world.component.ts`.
-
-```typescript
-import { Component, OnInit } from '@angular/core';
-import '../dbr'; // import side effects. The license, engineResourcePath, so on.
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-
-@Component({
-  selector: 'app-hello-world',
-  templateUrl: './hello-world.component.html',
-  styleUrls: ['./hello-world.component.css']
-})
-export class HelloWorldComponent implements OnInit {
-  bShowScanner = true;
-  bShowImgDecode = false;
-  async ngOnInit(): Promise<void> {
-    // Load the library on page load to speed things up.
-    try {
-      await BarcodeScanner.loadWasm();
-    } catch (ex: any) {
-      let errMsg;
-      if (ex.message.includes("network connection error")) {
-        errMsg = "Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.";
-      } else {
-        errMsg = ex.message||ex;
-      }
-      console.error(errMsg);
-      alert(errMsg);
-    }
-  }
-  showScanner(): void {
-    this.bShowScanner = true;
-    this.bShowImgDecode = false;
-  }
-  showImgDecode(): void {
-    this.bShowScanner = false;
-    this.bShowImgDecode = true;
-  }
-}
-```
-
-> NOTE :
->
-> * The method `loadWasm()` initializes the library in the background.
-
-### Add the hello-world component to `app.component.html`
-
-Edit the file `app.component.html` to contain nothing but the following
-
-```html
-<app-hello-world></app-hello-world>
-```
-
-* Try running the project.
-
-```cmd
-ng serve
-```
-
-If you have followed all the steps correctly, you should now have a functioning page that allows you to scan barcodes from a webcam or a built-in camera. Additionally, if you want to decode a local image, you can click the `Image Decode` button and select the image you want to decode. Any barcodes that are detected will be displayed in a dialog.
-
-## Development server
-
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-## Build
-
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
-
-## Support
-
-If you have any questions, feel free to contact Dynamsoft support via [email](mailto:support@dynamsoft.com) or live chat via the "Chat" button.

-# JavaScript Hello World Sample - Electron
-
-[Electron](https://www.electronjs.org/) is a framework for creating native applications with web technologies. Follow this guide to learn how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into an Electron application.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/9.read-video-electron">Read Barcodes from Camera - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) installed. `node 14.16.0` is used in this article.
-
-## Create an empty Application
-
-Create a folder with the name "read-video-electron" and a package.json file inside it with the following content:
-
-```json
-{
-  "name": "read-video-electron",
-  "version": "1.0.0",
-  "description": "How to read barcodes from a video input in an Electron App",
-  "main": "main.js",
-  "scripts": {
-    "start": "electron .",
-    "test": "echo \"Error: no test specified\" && exit 1"
-  },
-  "author": "tom@dynamsoft.com",
-  "dependencies": {
-    "electron": "14.0.1",
-    "dynamsoft-javascript-barcode": "9.6.1"
-  }
-}
-```
-
-Then, run `npm install` to install the dependencies.
-
-```cmd
-npm install
-```
-
-## Start to implement
-
-### Create a main.js file
-
-As defined in the package.json file, main.js is the entry point of the application, we define it like this:
-
-```javascript
-const { app, BrowserWindow } = require('electron')
-
-function createWindow() {
-    const win = new BrowserWindow({
-        width: 800,
-        height: 600,
-    })
-    win.loadFile('index.html')
-}
-
-app.whenReady().then(() => {
-    createWindow()
-    app.on('activate', () => {
-        if (BrowserWindow.getAllWindows().length === 0) {
-            createWindow()
-        }
-    })
-})
-
-app.on('window-all-closed', () => {
-    if (process.platform !== 'darwin') {
-        app.quit()
-    }
-})
-```
-
-Two modules are imported in this file:
-
-* `app`: controls the application's event lifecycle.
-* `BrowserWindow`: creates and manages application windows.
-
-The code basically opens index.html in a window. For more information, check out [Electron Quick Start](https://www.electronjs.org/docs/latest/tutorial/quick-start).
-
-### Create an index.html file
-
-Create the page to be loaded in the created window.
-
-```html
-<!DOCTYPE html>
-<html>
-
-<head>
-    <meta charset="UTF-8">
-    <title>Read barcodes from a video input in Electron!</title>
-    <link href="style.css" rel="stylesheet">
-</head>
-
-<body>
-    <h1>Read barcodes from a video input</h1>
-    <button id='readBarcode'>Read Barcode via Camera</button>
-    <div id="UIElement">
-        <div id="barcodeScannerUI"></div>
-    </div>
-    <input id="resultText" type="text" readonly="true">
-    <script src="./node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-    <script src="action.js"></script>
-</body>
-
-</html>
-```
-
-The page loads action.js which makes use of the library to create a barcode scanner and read barcodes from a video input:
-
-```javascript
-(async function () {
-    Dynamsoft.DBR.BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-    Dynamsoft.DBR.BarcodeReader.loadWasm();
-    let pScanner = null;
-    document.getElementById('readBarcode').onclick = async () => {
-        try {
-            let scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-            scanner.onFrameRead = results => {
-                if (results.length) {
-                    console.log(results);
-                }
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                const format = result.barcodeFormat ? result.barcodeFormatString : result.barcodeFormatString_2;
-                document.getElementById('resultText').value = format + ': ' + txt;
-            };
-            document.getElementById("barcodeScannerUI").appendChild(scanner.getUIElement());
-            await scanner.show();
-        } catch (ex) {
-            alert(ex.message);
-            throw ex;
-        }
-    };
-})();
-```
-
-Also, style.css defines the styles for the UI
-
-```css
-body {
-    text-align: center;
-}
-
-#barcodeScannerUI {
-    width: 100%;
-    height: 100%;
-}
-
-#UIElement {
-    margin: 2vmin auto;
-    text-align: center;
-    font-size: medium;
-    height: 40vh;
-    width: 80vw;
-}
-#resultText {
-    display: block;
-    margin: 0 auto;
-    padding: 0.4rem 0.8rem;
-    color: inherit;
-    width: 80vw;
-    border: none;
-    font-size: 1rem;
-    border-radius: 0.2rem;
-    text-align: center;
-}
-```
-
-## Run the application
-
-Run the application with the following command and see how it goes.
-
-```cmd
-npm start

-# JavaScript Hello World Sample - Next.js
-
-[Next.js](https://nextjs.org/) is an open-source development framework built on top of Node.js enabling [React](https://reactjs.org/) based web applications functionalities such as server-side rendering and generating static websites. Follow this guide to learn how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into a Next.js application. Note that in this sample we will use `TypeScript`.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/7.read-video-nextjs">Hello World in Next.js - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) installed. `node 14.21.3` and `next 13.2.4` are used in the example below.
-
-## Create the sample project
-
-### Create a Bootstrapped Raw Next.js Application
-
-```cmd
-npx create-next-app@latest --typescript
-```
-
-### **CD** to the root directory of the application and install the dependencies
-
-```cmd
-npm install dynamsoft-javascript-barcode
-```
-
-## Start to implement
-
-### Add a file dbr.ts at the root of the application to configure the library
-
-```jsx
-import { BarcodeReader } from 'dynamsoft-javascript-barcode';
-BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```
-
-> Note:
-> * `license` specify a license key to use the library. You can visit [https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js) to get your own trial license good for 30 days. 
-> * `engineResourcePath` tells the library where to get the necessary resources at runtime.
-
-### Create a directory "components" and create the following files inside it to represent three components
-
-* VideoDecode.tsx
-* ImgDecode.tsx
-* HelloWorld.tsx
-
-### Edit the `VideoDecode` component
-
-* In VideoDecode.tsx, add code for initializing and destroying the `BarcodeScanner` instance. The `VideoDecode` component uses `BarcodeScanner` class of the library to help decode barcodes via camera.
-
-```tsx
-import { BarcodeScanner } from "dynamsoft-javascript-barcode";
-import React from 'react';
-import styles from '@/styles/VideoDecode.module.css'
-
-class VideoDecode extends React.Component {
-    pScanner: Promise<BarcodeScanner>|null = null;
-    elRef: React.RefObject<HTMLDivElement> = React.createRef();
-    async componentDidMount() {
-        try {
-            const scanner = await (this.pScanner = BarcodeScanner.createInstance());
-            // Should judge if scanner is destroyed after 'await', as in development React runs setup and cleanup one extra time before the actual setup in Strict Mode. 
-            if(scanner.isContextDestroyed()) return;
-            await scanner.setUIElement(this.elRef.current!);
-            // Should judge if scanner is destroyed after 'await', as in development React runs setup and cleanup one extra time before the actual setup in Strict Mode. 
-            if(scanner.isContextDestroyed()) return;
-            scanner.onFrameRead = results => {
-                for (let result of results) {
-                    console.log(result.barcodeText);
-                }
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            }
-            await scanner.open();
-        } catch (ex: any) {
-            if (ex.message.indexOf("network connection error")) {
-                let customMsg = "Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.";
-                console.log(customMsg);
-                alert(customMsg);
-            }
-            throw ex;
-        }
-    }
-    async componentWillUnmount() {
-        if (this.pScanner) {
-            (await this.pScanner).destroyContext();
-            console.log('BarcodeScanner Component Unmount');
-        }
-    }
-    shouldComponentUpdate() {
-        // Never update UI after mount, dbrjs sdk use native way to bind event, update will remove it.

-> Note:
-> * The html code in `render()` and the following code builds the UI for the library.
-> 
->   ```jsx
->   await scanner.setUIElement(this.elRef.current!);
->   ```
-> 
-> * To release resources timely, the `BarcodeScanner` instance is destroyed with the component in the callback `componentWillUnmount`.
-> * The component should never update (check the code for `shouldComponentUpdate()`) so that events bound to the UI stay valid.
-
-* Create 'VideoDecode.module.css' under '/styles/' and define the style of the component in it

-import React, { ChangeEvent, Component } from 'react'
-import { BarcodeReader } from "dynamsoft-javascript-barcode";

-
-### Add the HelloWorld component to /pages/index.tsx
-
-In index.tsx, import the `HelloWorld` component:
-
-```jsx
-import HelloWorld from '../components/HelloWorld'
-```
-
-Change the &lt;main&gt; tag like this:
-
-```jsx
-<main className={styles.main}>
-  <div className={styles.UIElement}>
-    <HelloWorld />
-  </div>
-</main>
-```
-
-* Define the style of the "App" element in styles/Home.module.css
-
-```css
-.UIElement {
-  margin: 2vmin auto;
-  text-align: center;
-  font-size: medium;
-  width: 80vw;
-}
-```
-
-* Try running the project.
-
-```cmd
-npm run dev
-```
-
-If you have followed all the steps correctly, you should now have a functioning page that allows you to scan barcodes from a webcam or a built-in camera. Additionally, if you want to decode a local image, you can click the `Image Decode` button and select the image you want to decode. Any barcodes that are detected will be displayed in a dialog.
-
-## Project Setup
-
-```sh
-npm install
-```
-
-### Compile and Hot-Reload for Development
-
-```sh
-npm run dev
-```
-
-### Type-Check, Compile and Minify for Production
-
-```sh
-npm run build
-```

-# JavaScript Hello World Sample - NuxtJS
-
-[Nuxt](https://nuxtjs.org/) is a higher-level framework that builds on top of [Vue](https://vuejs.org/). Check out the following guide on how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into a Nuxt application. Note that in this sample we will use `TypeScript`.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/8.read-video-nuxtjs">Hello World in Nuxt - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) installed. `node 14.21.3` and `nuxt 3.2.3` are used in this article.
-
-## Create the sample project
-
-### Create a Bootstrapped Nuxt Application
-
-```cmd
-npx nuxi@latest init read-video-nuxtjs
-```
-
-You will be asked to configure quite a few things for the application during the creation. In our example, we chose the default one in every step.
-
-### **CD** to the root directory of the application and install the dependencies
-
-```cmd
-cd read-video-nuxtjs
-npm install dynamsoft-javascript-barcode
-```
-
-## Start to implement
-
-### Add a file "dbr.ts" at the root of the app to configure the library
-
-```typescript
-import { BarcodeReader } from 'dynamsoft-javascript-barcode';
-BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```
-
-> Note:
->
-> * `license` specify a license key to use the library. You can visit [https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js) to get your own trial license good for 30 days.
-> * `engineResourcePath` tells the library where to get the necessary resources at runtime.
-
-### Create a directory "components" and create the following files inside it to represent three components
-
-* VideoDecode.vue
-* ImgDecode.vue
-* HelloWorld.vue
-
-### Edit the `VideoDecode` component
-
-* Add a file `VideoDecode.vue` under "/components/" as the `VideoDecode` component. The `VideoDecode` component uses `BarcodeScanner` class of the library to help decode barcodes via camera.
-
-* In `VideoDecode.vue`, add code for initializing and destroying the `BarcodeScanner` instance.
-
-```vue
-<script setup lang="ts">
-import { onBeforeUnmount, onMounted, ref, getCurrentInstance } from "vue";
-import type { Ref } from 'vue'
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode'
-
-const pScanner: Ref<null | Promise<BarcodeScanner>> = ref(null);
-const elRefs: Ref<null | HTMLElement> = ref(null);
-onMounted(async () => {
-  try {
-    const internalInstance = getCurrentInstance();
-    elRefs.value = internalInstance?.refs.elRefs as HTMLElement;
-    const scanner = await (pScanner.value = BarcodeScanner.createInstance());
-    await scanner.setUIElement(elRefs.value);
-    scanner.onFrameRead = (results) => {
-      for (let result of results) {
-        console.log(result.barcodeText);
-      }
-    };
-    scanner.onUniqueRead = (txt) => {
-      alert(txt);
-    }
-    await scanner.open();
-  } catch (ex:any) {
-    let errMsg = ex.message||ex;
-    if (errMsg.includes("network connection error")) {
-      errMsg = "Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.";
-    }
-    console.error(errMsg);
-    alert(errMsg);
-  }
-});
-onBeforeUnmount(async () => {
-  if (pScanner.value) {
-    (await pScanner.value).destroyContext();
-    console.log('BarcodeScanner Component Unmount');
-  }
-});
-</script>

-If you have followed all the steps correctly, you should now have a functioning page that allows you to scan barcodes from a webcam or a built-in camera. Additionally, if you want to decode a local image, you can click the `Image Decode` button and select the image you want to decode. Any barcodes that are detected will be displayed in a dialog.

-# JavaScript Hello World Sample - PWA
-
-[PWA](https://web.dev/progressive-web-apps/) is short for Progressive Web Apps which stand for web applications that have been designed to behave like platform-specific (native) applications. Check out the following on how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into a PWA application.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/10.read-video-pwa">Hello World in PWA - Source Code</a>
-
-## Preparation
-
-We will try to turn our most basic hello world sample into a PWA. 
-
-First, create a file with the name "helloworld-pwa.html" and fill it with the following code:
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-
-<head>
-    <meta charset="utf-8">
-    <meta name="viewport" content="width=device-width,initial-scale=1.0">
-    <title>Dynamsoft Barcode Reader PWA Sample - Hello World (Decoding via Camera)</title>
-</head>
-
-<body>
-    <h1 style="font-size: 1.5em;">Hello World for PWA</h1>
-    Loading...
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js"></script>
-    <script>
-        Dynamsoft.DBR.BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-        (async function() {
-            try {
-                const scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-                scanner.onFrameRead = results => {
-                    console.log("Barcodes on one frame:");
-                    for (let result of results) {
-                        const format = result.barcodeFormatString;
-                        console.log(format + ": " + result.barcodeText);
-                    }
-                };
-                scanner.onUniqueRead = (txt, result) => {
-                    alert(txt);
-                    console.log("Unique Code Found: ", result);
-                }
-                await scanner.show();
-            } catch (ex) {
-                let errMsg = ex.message||ex;
-                console.error(errMsg);
-                alert(errMsg);
-            }
-        })();
-        
-        if ('serviceWorker' in navigator) {
-            navigator.serviceWorker.register('./service-worker.js');
-        };
-    </script>
-</body>
-
-</html>
-```
-
-Next, set up a secure environment (HTTPs) to run the page "helloworld-pwa.html". This is required because PWAs only run in secure environments.
-
-In our case, we use IIS to set up a secure site at "https://localhost" and the page is put at the root so that it can be accessed at "https://localhost/helloworld-pwa.html".
-
-## Make the app progressive
-
-### Register a service worker for offline support
-
-As the basis for PWAs, Service Workers are a virtual proxy between the browser and the network. A service worker can serve content offline, handle notifications and perform heavy calculations, etc. all on a separate thread.
-
-To use a service worker, we first need to register it. In the helloworld-pwa.html file, add the following at the end of the script:
-
-```javascript
-if ('serviceWorker' in navigator) {
-    navigator.serviceWorker.register('./service-worker.js');
-};
-```
-
-Create the service-worker.js file with the following content:
-
-```javascript
-// Files to cache
-const cacheName = 'helloworld-pwa';
-const appShellFiles = [
-    './helloworld-pwa.html',
-];
-
-// Installing Service Worker
-self.addEventListener('install', (e) => {
-    console.log('[Service Worker] Install');
-    e.waitUntil((async () => {
-        const cache = await caches.open(cacheName);
-        console.log('[Service Worker] Caching all: app shell and content');
-        await cache.addAll(appShellFiles);
-    })());
-});
-
-self.addEventListener('fetch', (e) => {
-    e.respondWith((async () => {
-        const r = await caches.match(e.request);
-        console.log(`[Service Worker] Fetching resource: ${e.request.url}`);
-        if (r) { return r; }
-        const response = await fetch(e.request);
-        const cache = await caches.open(cacheName);
-        console.log(`[Service Worker] Caching new resource: ${e.request.url}`);
-        if (e.request.method !== "POST")
-            cache.put(e.request, response.clone());
-        return response;
-    })());
-});
-```
-
-With the above code, the application can now work offline because the service worker will cache the page helloworld-pwa.html and its related resources.
-
-For more information, refer to [Making PWAs work offline with Service workers](https://developer.mozilla.org/en-US/docs/Web/Progressive_web_apps/Offline_Service_workers).
-
-> NOTE
-> 
-> Since the files are being cached, changes we make in later steps may not be reflected. Therefore, don't forget to clear the cache after a change is made. To do so, you can run the following in the browser console.
-> 
-> ```javascript
-> const cacheName = 'helloworld-pwa';
-> const cache = await caches.delete(cacheName);
-> ```
-
-### Use a web manifest file to make the application installable
-
-A web manifest file contains a list of information about a website in a JSON format. This information is used to present the web app correctly for installation on a device.
-
-In our example, we first create a file "helloworld-pwa.webmanifest" with the following content:
-
-```json
-{
-    "name": "Dynamsoft Barcode Reader Progressive Web App",
-    "short_name": "DBR-PWA",
-    "description": "Progressive Web App that reads barcodes from a video input with Dynamsoft Barcode Reader.",
-    "start_url": "./helloworld-pwa.html",
-    "scope": ".",
-    "display": "standalone",
-    "theme_color": "#B12A34",
-    "background_color": "#B12A34",
-    "icons": [
-        {
-          "src": "./dynamsoft-512x512.png",
-          "sizes": "512x512",
-          "type": "image/png"
-        },
-        {
-          "src": "./dynamsoft-192x192.png",
-          "sizes": "192x192",
-          "type": "image/png"
-        }
-    ]
-}
-```
-
-> The icon files can be found in the github repository.
-
-Then we include the file in the &lt;head&gt; block of the helloworld-pwa.html file:
-
-```html
-<link rel="manifest" href="helloworld-pwa.webmanifest">
-```
-
-For compatibility on safari, we need add some `meta` in `<head>`:
-
-```html
-<meta name="theme-color" content="#B12A34">
-<meta name="mobile-web-app-capable" content="yes">
-<meta name="apple-mobile-web-app-title" content="sample for ios">
-<meta name="apple-mobile-web-app-capable" content="yes">
-<meta name="apple-mobile-web-app-status-bar-style" content="default">
-<link rel="apple-touch-icon" sizes="192x192" href="./dynamsoft-192x192.png" />
-<link rel="apple-touch-icon" sizes="512x512" href="./dynamsoft-512x512.png" />
-```
-
-Now, if you open the application again in your browser, you will notice an install icon appear on the right side of the address bar. When you click on it, a pop-up will appear asking if you want to install the app.
-
-Once installed, you can use it like a native app.
-
-For offline use, you need to cache more files.
-
-service-worker.js
-```javascript
-const dbrVersion = "9.6.11";
-const dbrCdn = `https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@${dbrVersion}/dist/`;
-
-const appShellFiles = [
-    './helloworld-pwa.html',
-    './dynamsoft-192x192.png',
-    './dynamsoft-512x512.png',
-    './helloworld-pwa.json',
-    `${dbrCdn}dbr.js`,
-    `${dbrCdn}dbr-${dbrVersion}.full.wasm`,
-    `${dbrCdn}dbr-${dbrVersion}.full.wasm.js`,
-    `${dbrCdn}dbr-${dbrVersion}.browser.worker.js`,
-];
-```
-

-# JavaScript Hello World Sample - React
-
-[React](https://reactjs.org/) is a JavaScript library meant explicitly for creating interactive UIs. Follow this guide to learn how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into a React application. Note that in this sample we will use `TypeScript` and define components as classes. Also, there is another sample `read-video-react-hooks` showing using `Hooks` in React.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/4.read-video-react">Hello World in React - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) installed. `node 14.21.3` and `react 18.2.0` used in the example below.
-
-## Create the sample project
-
-### Create a Bootstrapped Raw React Application with TypeScript
-
-```cmd
-npx create-react-app read-video-react --template typescript
-```
-
-### **CD** to the root directory of the application and install the library
-
-```cmd
-cd read-video-react
-npm install dynamsoft-javascript-barcode
-```
-
-## Start to implement
-
-### Add a file "dbr.ts" under "/src/" to configure the library
-
-```typescript
-import { BarcodeReader } from 'dynamsoft-javascript-barcode';
-BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```
-
-> Note:
->
-> * `license` specify a license key to use the library. You can visit [https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js) to get your own trial license good for 30 days.
-> * `engineResourcePath` tells the library where to get the necessary resources at runtime.
-
-### Build directory structure
-
-* Create a directory "components" under "/src/", and then create another three directories "HelloWorld", "VideoDecode" and "ImgDecode" under "/src/components/".
-
-### Create and edit the `VideoDecode` component
-
-* Create `VideoDecode.tsx` and `VideoDecode.css` under "/src/components/VideoDecode/". The `VideoDecode` component uses `BarcodeScanner` class of the library to decode barcodes via camera.
-
-* In `VideoDecode.tsx`, add code for initializing and destroying the `BarcodeScanner` instance.
-
-```tsx
-import { BarcodeScanner } from "dynamsoft-javascript-barcode";
-import React from 'react';
-import './VideoDecode.css'
-
-class VideoDecode extends React.Component {
-    pScanner: Promise<BarcodeScanner>|null = null;
-    elRef: React.RefObject<HTMLDivElement> = React.createRef();
-    async componentDidMount() {
-        try {
-            const scanner = await (this.pScanner = BarcodeScanner.createInstance());
-            // Should judge if scanner is destroyed after 'await', as in development React runs setup and cleanup one extra time before the actual setup in Strict Mode. 
-            if(scanner.isContextDestroyed()) return;
-            await scanner.setUIElement(this.elRef.current!);
-            // Should judge if scanner is destroyed after 'await', as in development React runs setup and cleanup one extra time before the actual setup in Strict Mode. 
-            if(scanner.isContextDestroyed()) return;
-            scanner.onFrameRead = results => {
-                for (let result of results) {
-                    console.log(result.barcodeText);
-                }
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            }
-            await scanner.open();
-        } catch (ex: any) {
-            if (ex.message.indexOf("network connection error")) {
-                let customMsg = "Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.";
-                console.log(customMsg);
-                alert(customMsg);
-            }
-            throw ex;
-        }
-    }
-    async componentWillUnmount() {
-        if (this.pScanner) {
-            (await this.pScanner).destroyContext();
-            console.log('BarcodeScanner Component Unmount');
-        }
-    }
-    shouldComponentUpdate() {
-        // Never update UI after mount, dbrjs sdk use native way to bind event, update will remove it.
-        return false;
-    }
-    render() {
-        return (

-* Create `ImgDecode.tsx` and `ImgDecode.css` under "/src/components/ImgDecode/". The `ImgDecode` component uses `BarcodeReader` class of the library to help decode barcodes in an image.
-
-* In `ImgDecode.tsx`, add code for initializing and destroying the `BarcodeReader` instance.

-    </div>
-  );
-}
-
-export default App;
-```
-
-* Try running the project.
-
-```cmd
-npm start
-```
-
-If you have followed all the steps correctly, you should now have a functioning page that allows you to scan barcodes from a webcam or a built-in camera. Additionally, if you want to decode a local image, you can click the `Image Decode` button and select the image you want to decode. Any barcodes that are detected will be displayed in a dialog.
-
-## Development server
-
-Runs the app in the development mode.\
-Open "http://localhost:3000" to view it in the browser.
-
-The page will reload if you make edits.\
-You will also see any lint errors in the console.
-
-## Build
-
-Builds the app for production to the `build` folder.\
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.\
-Your app is ready to be deployed!

-# JavaScript Hello World Sample - Read An Image
-
-In most cases, users of Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") reads barcodes from a video input. In this article, we will discuss an uncommon usage of the library: reading barcodes from existing images.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/1.hello-world/2.read-an-image.html">Read Barcodes from An Existing Image - Source Code</a>
-
-## Preparation
-
-In this article, we'll make use of the library through the `jsDelivr` CDN. Make sure you can access this file "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js".
-
-## Create the sample page
-
-* Create an empty web page and name it "read-an-image.html" with the following code:
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-
-<head>
-    <meta charset="utf-8">
-    <meta name="viewport" content="width=device-width,initial-scale=1.0">
-    <title>Dynamsoft Barcode Reader Sample - Read an Image</title>
-</head>
-
-<body>
-    <script></script>
-</body>
-
-</html>
-```
-
-* Add reference to the library in the page "head".
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js"></script>
-```
-
-* In the page "body", add an input for image selecting and a div for displaying the barcode results.
-
-```html
-<input id="input-file" type="file" accept="image/png,image/jpeg,image/bmp,image/gif">
-<div id="results"></div>
-```
-
-* Add an event listner for the file input, then add barcode reading code in the callback.
-
-```javascript
-let pReader = null;
-Dynamsoft.DBR.BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-document.getElementById('input-file').addEventListener('change', async function() {
-    try {
-        let resDIV = document.getElementById('results');
-        let reader = await (pReader = pReader || Dynamsoft.DBR.BarcodeReader.createInstance());
-        for (let i = 0; i < this.files.length; ++i) {
-            // Actually there will only be one file here (no 'multiple' attribute)
-            let file = this.files[i];
-            // Decode the file
-            let results = await reader.decode(file);
-            if (results.length === 0) {
-                resDIV.innerHTML = "No Barcode Found!";
-                return;
-            }
-            var info = "";
-            for (let result of results) {
-                const format = result.barcodeFormat ? result.barcodeFormatString : result.barcodeFormatString_2;
-                info += "<p>" + format + ": " + result.barcodeText + "</p>";
-            }
-            resDIV.innerHTML = info;
-        }
-    } catch (ex) {
-        alert(ex.message);
-    }
-});
-```
-
-> NOTE
->  
-> * An instance of the library is created when an image is selected for the first time.
-> * The method `decode()` takes the file as the input, reads it and returns the results.
-
-In your application, the input may not be a file, the method `decode()` can handle the following types of input: `Blob`, `Buffer`, `ArrayBuffer`, `Uint8Array`, `Uint8ClampedArray`, `HTMLImageElement`, `HTMLCanvasElement`, `HTMLVideoElement`, `string`.

-# JavaScript Hello World Sample - RequireJS
-
-[RequireJS](https://requirejs.org/) is a JavaScript file and module loader. In this article, we will take a look at how to use the Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") with RequireJS as shown in the code:
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/1.hello-world/11.read-video-requirejs.html">Read Barcodes from Camera - RequireJS - Source Code</a>
-
-## Create a simple page for barcode reading with RequireJS
-
-### Include RequireJS on the page
-
-The first step is to load "require.js" on the page:
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/requirejs@2.3.6/require.js"></script>
-```
-
-### Use RequireJS to load the library
-
-Once RequireJS is enalbed, we can use the API `requirejs` to load the library from a CDN:
-
-```javascript
-requirejs(['https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js'],
-    function({
-        BarcodeScanner
-    }) {});
-```
-
-As shown above, the `requirejs` method loads the library and imports two key objects to be used in the context. We use `DBR` to set up the library and then use `BarcodeScanner` to read barcodes from a video input.
-
-```javascript
-BarcodeScanner.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-let pScanner = null;
-document.getElementById('readBarcode').onclick = async function() {
-    try {
-        let scanner = await (pScanner = pScanner || BarcodeScanner.createInstance());
-        scanner.onFrameRead = results => {
-            console.log("Barcodes on one frame:");
-            for (let result of results) {
-                const format = result.barcodeFormat ? result.barcodeFormatString : result.barcodeFormatString_2;
-                console.log(format + ": " + result.barcodeText);
-            }
-        };
-        scanner.onUniqueRead = (txt, result) => {
-            alert(txt);
-            console.log("Unique Code Found: " + result);
-        }
-        await scanner.show();
-    } catch (ex) {
-        alert(ex.message);
-        throw ex;
-    }
-};

-# JavaScript Hello World Sample - Vue
-
-[Vue](https://vuejs.org/) is a progressive framework for building user interfaces. Check out the following guide on how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into a Vue 2 application.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/5.read-video-vue">Hello World in Vue - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) installed. `node 14.21.3` and `vue 2.7.7` are used in the example below. 
-
-## Create the sample project
-
-### Create a Bootstrapped Raw Vue Application
-
-```cmd
-npm create vue@2
-```
-
-### **CD** to the root directory of the application and install the dependencies
-
-```cmd
-npm install
-npm install dynamsoft-javascript-barcode
-```
-
-## Start to implement
-
-### Add a file "dbr.js" under "/src/" to configure the library
-
-```typescript
-import { BarcodeReader } from 'dynamsoft-javascript-barcode';
-BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```
-
-> Note:
->
-> * `license` specify a license key to use the library. You can visit [https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js) to get your own trial license good for 30 days. 
-> * `engineResourcePath` tells the library where to get the necessary resources at runtime.
-
-### Create and edit the `VideoDecode` component
-
-* Add a file `VideoDecode.vue` under "/components/" as the `VideoDecode` component. The `VideoDecode` component uses `BarcodeScanner` class of the library to help decode barcodes via camera.
-
-* In `VideoDecode.vue`, add code for initializing and destroying the `BarcodeScanner` instance.
-

-### Add the `HelloWorld` component to `App.vue`
-
-Edit the file `App.vue` to be like this
-
-```vue

-  <div id="app">
-    <HelloWorld />
-  </div>
-</template>
-
-<script>
-import HelloWorld from "./components/HelloWorld.vue";
-
-export default {
-  name: "App",
-  components: {
-    HelloWorld,
-  },
-};
-</script>
-
-<style>
-</style>
-```
-
-* Try running the project.
-
-```cmd
-npm run dev
-```
-
-If you followed all the steps correctly, you will have a working page that turns one of the cameras hooked to or built in your computer or mobile device into a barcode scanner. Also, if you want to decode a local image, just click the `Image Decode` button and select the image you want to decode. Once barcodes are found, the results will show in a dialog. 
-
-## Project setup

-### Compile and Hot-Reload for Development
-
-```sh
-npm run dev
-```

-# JavaScript Hello World Sample - Vue 3
-
-[Vue 3](https://v3.vuejs.org/) is version 3 of Vue which is a progressive framework for building user interfaces. Check out the following guide on how to implement Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") into a Vue 3 application. Note that in this sample we will use `TypeScript`.
-
-## Official Sample
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/9.x/1.hello-world/6.read-video-vue3">Hello World in Vue 3 - Source Code</a>
-
-## Preparation
-
-Make sure you have [node](https://nodejs.org/) installed. `node 14.21.3` and `vue 3.2.47` are used in the example below. 
-
-## Create the sample project
-
-### Create a Bootstrapped Raw Vue Application
-
-```cmd
-npm create vue@3
-# When asked 'Add TypeScript?', select 'Yes'.
-```
-
-### **CD** to the root directory of the application and install the dependencies
-
-```cmd
-npm install
-npm install dynamsoft-javascript-barcode
-```
-
-## Start to implement
-
-### Add a file "dbr.ts" under "/src/" to configure the library
-
-```typescript
-import { BarcodeReader } from 'dynamsoft-javascript-barcode';
-BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-BarcodeReader.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```
-
-> Note:
->
-> * `license` specify a license key to use the library. You can visit [https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=sample&product=dbr&package=js) to get your own trial license good for 30 days. 
-> * `engineResourcePath` tells the library where to get the necessary resources at runtime.
-
-### Create and edit the `VideoDecode` component
-
-* Add a file `VideoDecode.vue` under "/components/" as the `VideoDecode` component. The `VideoDecode` component uses `BarcodeScanner` class of the library to help decode barcodes via camera.
-
-* In `VideoDecode.vue`, add code for initializing and destroying the `BarcodeScanner` instance.
-
-```vue
-<script setup lang="ts">
-import { onBeforeUnmount, onMounted, ref, getCurrentInstance } from "vue";
-import type { Ref } from 'vue'
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode'
-
-const pScanner: Ref<null | Promise<BarcodeScanner>> = ref(null);
-const elRefs: Ref<null | HTMLElement> = ref(null);
-onMounted(async () => {
-  try {
-    const internalInstance = getCurrentInstance();
-    elRefs.value = internalInstance?.refs.elRefs as HTMLElement;
-    const scanner = await (pScanner.value = BarcodeScanner.createInstance());
-    await scanner.setUIElement(elRefs.value);
-    scanner.onFrameRead = (results) => {
-      for (let result of results) {
-        console.log(result.barcodeText);
-      }
-    };
-    scanner.onUniqueRead = (txt) => {
-      alert(txt);
-    }
-    await scanner.open();
-  } catch (ex:any) {
-    let errMsg = ex.message||ex;
-    if (errMsg.includes("network connection error")) {
-      errMsg = "Failed to connect to Dynamsoft License Server: network connection error. Check your Internet connection or contact Dynamsoft Support (support@dynamsoft.com) to acquire an offline license.";
-    }
-    console.error(errMsg);
-    alert(errMsg);
-  }
-});
-onBeforeUnmount(async () => {
-  if (pScanner.value) {
-    (await pScanner.value).destroyContext();
-    console.log('BarcodeScanner Component Unmount');
-  }
-});

-# JavaScript Parameter Settings Samples
-
-Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") is built based on Dynamsoft's algorithm. The algorithm is very flexible and has many configurable parameters. In this article, we'll take a look at how the library makes use of these parameters.
-
-Please note that most of the styling is common across the samples in this sample set. To improve the readability, we grouped the styling all in one file, settings-css.css. Additionally, the samples also share the same scanner initialization code. For the sake of clarity, the initialization code was also grouped in the same JS file, initScanner.js, and referenced throughout the different samples in this set.
-
-## Specify the Barcode Types and Number of Barcodes Per Image
-
-In many scenarios, an application only needs to decode one or a few types of barcodes that are predetermined. In fact, the algorithm can operate more efficiently when it is aware of the number of barcodes expected on an image. The following code snippet demonstrates how to decode two QR codes from an image.
-
-```javascript
-const settings = await scanner.getRuntimeSettings();
-settings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-settings.expectedBarcodesCount = 2;
-await scanner.updateRuntimeSettings(settings);
-```

-
-## Set Localization and Binarization Modes
-
-Localization and binarization are two essential steps in the barcode reading process. 
-
-* Localization Modes
-
-Localization modes specify how the algorithm localize a barcode. At present, 8 modes are available: "Connected Blocks", "Statistics", "Lines", "Scan Directly", "Statistics Marks", "Statistics Postal Code", "Center" and "OneD Fast Scan". More information can be found [here](https://www.dynamsoft.com/barcode-reader/parameters/reference/localization-modes.html?ver=latest). A barcode reading session will attempt all of the set modes. The session will end once either the predefined number of barcodes are found or all of the set modes have been completed. The following code shows how to set multiple modes.
-
-```javascript
-const settings = await scanner.getRuntimeSettings();
-settings.localizationModes = [2, 16, 4, 8, 32, 64, 0, 0];
-await scanner.updateRuntimeSettings(settings);
-```
-
-Note that each mode is represented by a number.
-
-Read more on [How to use different localization modes](https://www.dynamsoft.com/barcode-reader/parameters/scenario-settings/how-to-set-localization-modes.html).
-
-* Binarization Modes
-
-Binarization modes specify how the algorithm binarizes a colored or gray image. Right now, there are only two modes available: "Local Block" and "Threshold". More information can be found [here](https://www.dynamsoft.com/barcode-reader/parameters/reference/binarization-modes.html?ver=latest).
-
-For each mode, there are a few arguments to fine-tune it for best performance. Read more on [How to configure the binarization parameters](https://www.dynamsoft.com/barcode-reader/parameters/scenario-settings/how-to-set-binarization-modes.html?ver=latest).
-
-The following official sample demonstrates how to set Localization and Binarization modes.

-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/3.settings/2.localizationModes-binarizationModes.html">Localization and Binarization - Source Code</a>
-
-## Set Deblur Modes and Scale-up Modes
-
-* Deblur Modes
-
-The barcode reader often needs to handle blurry images, setting the deblur modes will help the algorithm better process them. In the library, there are 7 available modes: "Direct Binarization", "Threshold_Binarization", "Gray_Equalization", "Smoothing", "Morphing", "Deep_Analysis" and "Sharpening". More information can be found [here](https://www.dynamsoft.com/barcode-reader/parameters/reference/deblur-modes.html?ver=latest). A barcode reading session will attempt all of the set modes. The session will end once either the predefined number of barcodes are found or all of the set modes have been completed. The following code shows how to set multiple deblur modes.
-
-```javascript
-const settings = await scanner.getRuntimeSettings();
-settings.deblurModes = [1, 2, 4, 8, 0, 0, 0, 0, 0, 0];
-await scanner.updateRuntimeSettings(settings);
-```
-
-* Scale-up Modes
-
-In many cases, the barcodes appear very small on the image and makes it difficult to read. The scale-up modes can be used to enlarge such barcodes before reading them. In the library, there are 2 available modes: "Linear_Interpolation" and "Nearest_Neighbour_Interpolation". More information can be found [here](https://www.dynamsoft.com/barcode-reader/parameters/reference/scale-up-modes.html?ver=latest).
-
-For each mode, there are a few arguments to fine-tune it for best performance. Read more on [How to read barcodes with small module sizes](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/read-barcodes-with-small-module-size.html).
-
-The following official sample demonstrates how to set Deblur modes and Scale-up modes.

-
-## Deformation-Resisting Modes and Barcode-Complement Modes
-
-* Deformation-Resisting Modes
-
-As the name suggests, deformation-resisting modes deal with deformed barcocdes. Read more on [How to deal with deformed barcodes](https://www.dynamsoft.com/barcode-reader/parameters/scenario-settings/resist-deformation.html?ver=latest).
-
-For now, there is only one available mode: "General".
-
-The following code enables deformation resisting.
-
-```javascript
-const settings = await scanner.getRuntimeSettings();
-settings.furtherModes.deformationResistingModes = [2, 0, 0, 0, 0, 0, 0, 0];
-await scanner.updateRuntimeSettings(settings);
-```
-
-* Barcode-Complement Modes
-
-QR codes and Data Matrix codes can be picked up even if they are incomplete. Read more on [How to decode incomplete barcodes](https://www.dynamsoft.com/barcode-reader/parameters/scenario-settings/how-to-set-barcode-complememt-modes.html?ver=latest).
-
-The parameter for this case is called [ `BarcodeComplementMode` ](https://www.dynamsoft.com/barcode-reader/parameters/reference/barcode-complement-modes.html?ver=latest) which has only one available mode at present: "General".
-
-The following code enables incomplete barcode reading.
-
-```javascript
-const settings = await scanner.getRuntimeSettings();
-settings.furtherModes.deformationResistingModes = [2, 0, 0, 0, 0, 0, 0, 0];
-await scanner.updateRuntimeSettings(settings);
-```
-
-The following official sample showcases deformation resisting and barcode complementing.
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/3.settings/4.deformed-incomplete-barcodes.html">Deformation-Resisting Modes and Barcode-Complement Modes - Source Code</a>
-
-## Define or Detect the Region of Interest
-
-When reading barcodes from a video input, the barcode normally takes up only a small portion of the video frame. If the barcode always appear around the same spot, we can configure the ROI (Region of Interest) to speed up the barcode reading process. There are two ways to do this.
-
-* Manually define the ROI
-
-If the ROI is predetermined in the use case, we can manually set the limit. For example, the following only reads 25% of the central area.
-
-```javascript
-const settings = await scanner.getRuntimeSettings();
-settings.region.regionMeasuredByPercentage = 1;
-settings.region.regionLeft = 25;
-settings.region.regionTop = 25;
-settings.region.regionRight = 75;
-settings.region.regionBottom = 75;
-await scanner.updateRuntimeSettings(settings);
-```
-
-* Automatically detect the ROI
-
-To let the algorithm detect the ROI automatically, we can set the parameter [ `RegionPredetectionModes` ](https://www.dynamsoft.com/barcode-reader/parameters/reference/region-predetection-modes.html?ver=latest) which has four available modes: "General", "General_RGB_Contrast", "General_Gray_Contrast" and "General_HSV_Contrast". 
-
-For each mode, there are a few arguments to fine-tune it for best performance. Read more on [How To Use Region Predetection](https://www.dynamsoft.com/barcode-reader/parameters/scenario-settings/how-to-use-region-predetection.html?ver=latest).
-
-The following official sample showcases both ways to specify ROI.

-
-## Dealing with Dense Barcodes
-
-Some barcodes are designed to hold a lot of information which makes them very dense. To read such barcodes, we need to do two things
-
-1. Use a high resolution 
-2. Use the built-in "dense" template
-
-```javascript
-await scanner.setResolution(3840, 2160);
-await scanner.updateRuntimeSettings("dense");
-```
-
-The following official sample showcases the performance of picking up dense barcodes with specific settings.

-# JavaScript UI Customization Samples
-
-Dynamsoft Barcode Reader JavaScript SDK (hereafter called "the library") provides a built-in GUI to help developers build an interactive barcode reading interface.
-
-## Default GUI
-
-The following official sample demonstrates the default GUI built into the library.
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/2.ui-tweaking/1.read-video-show-result.html">Use the Default Camera UI - Source Code</a>
-
-**GUI Elements**
-
-If you check the GUI on the demo page, you will find that it consists of the following elements
-
-* The video element that streams the video from a camera
-* A laser beam moving vertically which indicates the working status of the library
-* A dropdown box for selecting a camera
-* A dropdown box for specifying the resolution for the selected camera
-* A close button that closes the GUI when clicked
-
-There are a few other elements
-
-* Before the video starts streaming, there is a spinner that indicates the loading process
-* When a barcode is found, the barcode is highlighted with an overlay
-* If no camera is found on the device or camera access is denied on the page, the GUI will show a camera icon, which, when clicked, allows the user to select a local image or invoke the system camera interface
-
-## Hide Built-in Controllers
-
-The default UI of the BarcodeReader class includes several elements that may not match the style of your application. The following code snippet demonstrates how to remove the camera selector, resolution selector, and close button, as well as change the background color:
-
-```html
-<div id="UIElement">
-    <span id='lib-load' style='font-size:x-large' hidden>Loading Library...</span>
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:100%;"></div>
-    </div>
-</div>
-```
-
-```javascript
-await scanner.setUIElement(document.getElementById('div-ui-container'));
-```
-
-Official sample:
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/2.ui-tweaking/2.read-video-no-extra-control.html">Hide Built-in Controllers - Source Code</a>
-
-## Use External Controllers
-
-Based on the previous sample, you can build your own UI elements to control the barcode scanning process.
-
-For example, the following code adds a camera selector
-
-```html
-<select id="cameraList"></select>
-```
-
-```javascript
-async function updateCameras() {
-    let cameras = await scanner.getAllCameras();
-    let cameraList = document.getElementById('cameraList');
-    cameraList.options.length = 0;
-    for (let camera of cameras) {
-        let opt = new Option(camera.label, camera.deviceId);
-        cameraList.options.add(opt);
-    }
-}
-document.getElementById('cameraList').onchange = async function() {
-    try {
-        await scanner.setCurrentCamera(document.getElementById('cameraList').value);
-    } catch (ex) {
-        alert('Play video failed: ' + (ex.message || ex));
-    }
-};
-```
-
-For more related customization, check out the following official sample:
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/2.ui-tweaking/3.read-video-with-external-control.html">Use External Controllers - Source Code</a>
-
-## Enlarge the Video Stream
-
-The library is usually used on mobile devices which have small screens. When scanning barcodes with the mobile camera, the video stream will be limited in the video element and may not be clear enough. Ideally, we should use the whole screen to play the video and find barcodes.
-
-The GUI is pure HTML. Thus modifying the size of the element is easy. The following code expands the element to fill the entire viewport:
-
-```javascript
-document.getElementById('UIElement').style.height = '100vh';
-document.getElementById('UIElement').style.width = '100vw';
-document.getElementById('UIElement').style.position = 'absolute';
-```
-
-Check out the following example code to see how you can expand the video stream to read a barcode and then restore it to its normal size:
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/2.ui-tweaking/4.difference-video-size.html">Enlarge the Video Stream - Source Code</a>
-
-## Customize the Default Ui
-
-Check out the following example code that demonstrates how to create a custom viewer that is vastly different from the default one. You can feel the possibilities of customization:
-
-* <a target = "_blank" href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/9.x/2.ui-tweaking/5.read-video-with-custom-default-ui.html">Customize the Default Ui - Source Code</a>
-

-## Read Barcodes and Fill Form Fields
-
-It's difficult to type long text on mobile devices, but if that text is encoded in a barcode, we can use the sdk to read the barcode and automatically enter the text.
-
-The following code shows how to automatically invoke the sdk to read a barcode and fill in an input box.
-
-```html
-<input id="input-to-fill" type="text" readonly="true" placeholder="Barcode Result">
-```
-
-```javascript
-let scanner = null;
-Dynamsoft.DBR.BarcodeReader.license = 'DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9';
-(async function () {
-    document.getElementById("input-to-fill").addEventListener('click', async function () {
-        try {
-            scanner = scanner || await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            scanner.onUniqueRead = (txt, result) => {
-                this.value = result.barcodeText;
-                scanner.hide();
-            };
-            await scanner.show();
-        } catch (ex) {
-            alert(ex.message);
-            throw ex;

-await scanner.setModeArgument("TextureDetectionModes", 0, "Sensitivity", "9");
-```
-
-## Display the intermediate result images or the original canvas
-
-The intermediate result images are created when `intermediateResultTypes` is set in `RuntimeSettings` . Then they can be returned with the method `getIntermediateResults()` . These images can be used to show and debug the barcode reading process. 
-
-The original canvas ( `oriCanvas` ) means the actual canvas which holds the image to be passed to the barcode reader engine for decoding. 
-
-> *NOTE*
->  
-> For efficiency, the library may utilize WebGL (Web Graphics Library) for preprocessing an image before passing it to the barcode reader engine. If WebGL is used, the image captured from the camera will not be rendered on the canvas, instead, it gets processed by WebGL first and then is passed to the barcode reader engine directly. In this case, there won't be an original canvas. Therefore, if `bSaveOriCanvas` is set to `true` for a `BarcodeReader` or `BarcodeScanenr` instance, the WebGL feature will be disabled for that instance.
->  
-> On the other hand, if WebGL is disabled and you try to get the intermediate result specified by `EnumIntermediateResultType.IRT_ORIGINAL_IMAGE` , it will be exactly the same image as you would get with `oriCanvas` .
-
-The following shows how to display these images on the page
-
-```html
-<div id='scannerV' style="width:50vw;height:50vh"></div>
-<div id='cvses'></div>
-```
-
-```javascript

-    /* The default of `_bUseWebgl` is true which means the intermediate result for  
-       IRT_ORIGINAL_IMAGE will be one that has been preprocessed by WebGL */
-    scanner._bUseWebgl = false;
-    document.getElementById('scannerV').appendChild(scanner.getUIElement());;
-    await scanner.updateRuntimeSettings('balance');
-    let rs = await scanner.getRuntimeSettings();

-
-## Display the original canvas or the intermediate result canvas
-
-The original canvases are saved when setting `ifSaveOriginalImageInACanvas` to `true`. The method `getOriginalImageInACanvas()` returns a canvas which holds the image to be passed to the barcode reader engine for decoding. 
-
-The intermediate result canvases are created when `intermediateResultTypes` is set to a value other than `IRT_NO_RESULT` . Then these intermediate result canvases can be returned with the method `getIntermediateCanvas()` to be used for showing and debugging the barcode reading process. 
-

If WebGL is used, the image captured from the camera will not be rendered on the canvas, instead, it gets processed by WebGL first and then is passed to the barcode reader engine directly. In this case, there won't be an original canvas.

-> Therefore, if `ifSaveOriginalImageInACanvas` is set to `true` for a `BarcodeScanenr` instance, the WebGL feature will be disabled for that instance.
->
-> You can manually disable the WebGL feature by setting `_bUseWebgl` as `false`. If WebGL is disabled, when you try to get the intermediate result canvas (with `getIntermediateCanvas()`) specified by `EnumIntermediateResultType.IRT_ORIGINAL_IMAGE` , the canvas will be exactly the same image as you would get with `getOriginalImageInACanvas()` .

-## Always draw a square as the scan region
-
-When reading square barcodes such as QR codes, it will help to keep the scan region also a square, the following code does the trick
-
-```javascript
-scanner.onPlayed = async info => {
-    let sideLen = Math.min(info.width,info.height)*0.4;
-    let precentW = Math.round(sideLen/info.width*100)
-    let precentH = Math.round(sideLen/info.height*100);
-    let rs = await scanner.getRuntimeSettings();
-    rs.region.regionLeft = (100 - precentW) / 2;
-    rs.region.regionRight = (100 + precentW) / 2;
-    rs.region.regionTop = (100 - precentH) / 2;
-    rs.region.regionBottom = (100 + precentH) / 2;
-    rs.region.regionMeasuredByPercentage = 1;
-    await scanner.updateRuntimeSettings(rs);

-
-## Account for newline characters in the barcode result
-
-When it comes to HTML, newline characters ( `\n` ) are not interpreted as they normally would. Therefore, if a barcode result contains a newline character, and you display the result in an modal dialogue box or some other text elements, then the newline character will probably be ignored.
-
-There are two ways in which you can resolve this:
-
-1. Wrap the element used to display the result in a `<pre>` element.
-2. Manually replace each `\n` character in the result with `<br>`
-
-## Show internal logs
-
-Include the following in your code to print internal logs in the console.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader._onLog = console.log;
-```
-
-## Cut down power usage
-
-> Applicable to version 9.2.10+
-
-BarcodeScanner is designed for best performance, which means once it starts scanning, it'll keep the CPU focused on barcode reading with no pause. As a result, it quickly drains the device battery and causes the device to overheat. To cut down power usage, we can configure two things:
-
-1. Pause the barcode reading when capturing the next video frame;
-2. Explicitly pause the SDK altogether for a short period after each successful read.
-
-```js
-const scanSettings = await scanner.getScanSettings();
-scanSettings.captureAndDecodeInParallel = false; // When set to false, the SDK will pause reading when capturing the next frame. Otherwise, the SDK will capture the next frame while reading the current frame, which means it never stops.
-scanSettings.intervalTime = 1000; // Tells the SDK to pause for 1 second after reading a frame before capturing the next frame.
-await scanner.updateScanSettings(scanSettings);
-```
-
-## Remove highlighting of unverified linear barcodes
-
-> Applicable to version 9.3.0+
-
-When linear barcodes are found but not verified, they will be highlighted in the video feed, but in a lighter color. If you wish to highlight only the verified barcodes, you can use the following code:
-
-```js
-scanner.barcodeFillStyleBeforeVerification = "transparent"; // default value: "rgba(248,252,0,0.2)"
-scanner.barcodeStrokeStyleBeforeVerification = "transparent"; // default value: "transparent"
-```
-
-## Set mode arguments
-
-To precisely control a mode, you can adjust its specific parameters.
-
-```javascript
-let settings = await scanner.getRuntimeSettings();
-
-/*
- * The following code sets the sensitivity of the TextureDetectionModes to 9
- */
-
-settings.furtherModes.textureDetectionModes = [
-    Dynamsoft.DBR.EnumTextureDetectionMode.TDM_GENERAL_WIDTH_CONCENTRATION, 0, 0, 0, 0, 0, 0, 0
-];
-
-await scanner.updateRuntimeSettings(settings);
-// The 2nd parameter 0 specifies the 0th mode of TextureDetectionModes, 
-// which is "Dynamsoft.DBR.EnumTextureDetectionMode.TDM_GENERAL_WIDTH_CONCENTRATION" in this case.
-await scanner.setModeArgument("TextureDetectionModes", 0, "Sensitivity", "9");
-```
-
-## Display images in different stages of the reading process
-
-The original canvases are saved when setting `ifSaveOriginalImageInACanvas` to `true`. The method `getOriginalImageInACanvas()` returns a canvas which holds the image to be passed to the barcode reader engine for decoding. 
-
-The intermediate result canvases are created when `intermediateResultTypes` is set to a value other than `IRT_NO_RESULT` . Then these intermediate result canvases can be returned with the method `getIntermediateCanvas()` to be used for showing and debugging the barcode reading process. 
-
-> *NOTE*
->  
-> For efficiency, the SDK may utilize WebGL (Web Graphics Library) for preprocessing an image before passing it to the barcode reader engine. If WebGL is used, the image captured from the camera will not be rendered on the canvas, instead, it gets processed by WebGL first and then is passed to the barcode reader engine directly. In this case, there won't be an original canvas.
-> 
-> Therefore, if `ifSaveOriginalImageInACanvas` is set to `true` for a `BarcodeScanenr` instance, the WebGL feature will be disabled for that instance.
->
-> You can manually disable the WebGL feature by setting `_bUseWebgl` as `false`. If WebGL is disabled, when you try to get the intermediate result canvas (with `getIntermediateCanvas()`) specified by `EnumIntermediateResultType.IRT_ORIGINAL_IMAGE` , the canvas will be exactly the same image as you would get with `getOriginalImageInACanvas()` .
-
-The following shows how to display these images on the page
-
-```html
-<div id='scannerV' style="width:50vw;height:50vh"></div>
-<div id='cvses'></div>
-```
-
-```javascript
-// original canvas
-(async () => {
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    document.getElementById('scannerV').appendChild(scanner.getUIElement());
-    scanner.ifSaveOriginalImageInACanvas = true;
-    scanner.onUniqueRead = async (txt, result) => {
-        try {
-            let cvs = scanner.getOriginalImageInACanvas();
-            document.getElementById('cvses').appendChild(cvs);
-            scanner.destroyContext();
-        } catch (ex) {
-            console.error(ex);
-        }
-    };
-    await scanner.show();
-})();
-```
-
-```javascript
-// intermediate result canvas
-(async () => {
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    document.getElementById('scannerV').appendChild(scanner.getUIElement());
-    let rs = await scanner.getRuntimeSettings();
-    rs.intermediateResultTypes = Dynamsoft.DBR.EnumIntermediateResultType.IRT_ORIGINAL_IMAGE;
-    await scanner.updateRuntimeSettings(rs);
-    scanner.onUniqueRead = async (txt, result) => {
-        try {
-            let cvss = await scanner.getIntermediateCanvas();
-            for (let cvs of cvss) {
-                document.getElementById('cvses').appendChild(cvs);
-            }
-            scanner.destroyContext();
-        } catch (ex) {
-            console.error(ex);
-        }
-    };
-    await scanner.show();
-})();
-```
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). 
-
-Some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.ui.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings" title="Apache">Apache</a>
-  + <a target="_blank" href="https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap" title="IIS">IIS</a>
-  + <a target="_blank" href="https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types" title="NGINX">NGINX</a>
-
-* Enable HTTPS
-
-  Due to the browser <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts" title="security restriction">security restriction</a> on camera video streaming access, a secure HTTPS connection is required to use the library with camera.
-
-  > For convenience, self-signed certificates can be used during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-```html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to [specify the location of the "engine" files](index.md#specify-the-location-of-the-engine-files).

-# Basic Customizations
-
-## Initializing
-
-The library is based on the `WebAssembly` standard; therefore, **on first use**, it needs some time to download and compile the `wasm` files. After first use, the browser may cache the file.
-
-`Dynamsoft.BarcodeReader.loadWasm` is the API to start the initialization.
-
-```javascript
-try{
-    await Dynamsoft.BarcodeReader.loadWasm();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-Other APIs like `Dynamsoft.BarcodeReader.createInstance` and `Dynamsoft.BarcodeScanner.createInstance` will also call `loadWasm` during initialization. The following demonstrates the most common usage. 
-
-```javascript
-let reader = null;
-let scanner = null;
-try{
-    reader = await Dynamsoft.BarcodeReader.createInstance();
-    scanner = await Dynamsoft.BarcodeScanner.createInstance();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-   **NOTE**: Including the library with a script tag doesn't automatically initialize the library. For better performance, you may want to call loadWasm to download and compile the wasm file in advance and create a reader or scanner instance later.   
-
-Initialization consists of the following steps:
-
-**1. Download**   
-    Download the necessary resources. Usually, we deploy the resources on CDN and set a long cache duration. If your web server is faster, you should put the resources on your own server instead of using the CDN.
-
-**2. Compile**    
-    The `wasm` files are automatically compiled once downloaded. The compilation time varies among different devices & browsers. While it takes less than a second on latest phones or PCs, it may take longer on older devices.
-
-**3. Initialize**  
-    The library needs to initialize every time the page loads. The initialization means creating an `BarcodeReader` or `BarcodeScanner` instance with specified settings.
-
-
-## Configuring Scanner Settings
-
-When creating an instance of the `BarcodeScanner` object, there are several configuration options. The following code shows some of the most popular ones:
-
-```javascript
-// set which camera and what resolution to use
-await scanner.updateVideoSettings({ video: { width: 1280, height: 720, facingMode: "environment" } });
-
-// use one of three built-in RuntimeSetting templates, 'speed' is recommended for decoding from a video stream
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code snippet below demonstrates how to specify which symbologies are enabled
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.EnumBarcodeFormat.BF_ONED | Dynamsoft.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period
-scanSettings.duplicateForgetTime = 20000;
-// set a scan interval so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see in the code, there are three types of configurations:
-
-- `get/updateVideoSettings`: Configures the data source, i.e., the video stream. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-- `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](../api-reference/global-interfaces.md#runtimesettings). Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-    e.g.,
-
-    ```javascript
-    await barcodeScanner.updateRuntimeSettings("speed");
-    await barcodeScanner.updateRuntimeSettings("balance");
-    await barcodeScanner.updateRuntimeSettings("coverage");
-    let settings = await barcodeScanner.getRuntimeSettings();
-    settings.localizationModes = [
-        Dynamsoft.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-        Dynamsoft.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-        Dynamsoft.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0];
-    settings.deblurLevel = 2;
-    await barcodeScanner.updateRuntimeSettings(settings);
-    ```
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`, `intervalTime` and `filter`, etc.
-
-## Customizing the UI
-
-The library provides a built-in UI for the `BarcodeScanner`object where the default scanner UI is defined in the file `dist/dbr.scanner.html`. There are 3 ways to customize it:
-
-1. Modify the file `dist/dbr.scanner.html` directly. This option is only possible when you deploy these files yourself instead of using the CDN.
-
-2. Copy the file `dist/dbr.scanner.html`, modify it and specify the new file as the default UI by its URL `Dynamsoft.BarcodeScanner.defaultUIElementURL = url`. Note: you must set `defaultUIElementURL` before you call `createInstance`.
-
-3. Build the UI into your own web page and call `scanner.setUIElement(HTMLElement)` to specify that element.
-
-
-The following is an example of the 3rd option above. 
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <div id="div-video-container">
-        <video class="dbrScanner-video" playsinline="true"></video>
-    </div>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@7.5.0-v1/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-    <script>
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-The element `div-video-container` is used as the UI this div contains the video element for showing the video stream.
-
-   **NOTE**: The class name of the video element must be set to `dbrScanner-video`.
-
-   ```html
-   <video class="dbrScanner-video" playsinline="true"></video>
-   ```
-
-### Cameras and Resolution Options
-
-Next, you can add the camera list and resolution list.
-
-   If the class names match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution`, the library will automatically populate the lists and handle the camera/resolution switching automatically.
-
-```html
-<select class="dbrScanner-sel-camera"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-```html
-<select class="dbrScanner-sel-resolution"></select>
-```
-   8 default resolutions are populated automatically.
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-The following code shows how to display a custom set of resolution options.
-
-```html
-<select class="dbrScanner-sel-resolution">
-    <option class="dbrScanner-opt-gotResolution" value="got"></option>
-    <option data-width="1920" data-height="1080">1920 x 1080</option>
-    <option data-width="1280" data-height="720">1280 x 720</option>
-    <option data-width="640" data-height="480">640 x 480</option>
-</select>
-```
-
-   **Possible Issue**: Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used.
-
-   **Solution**: Add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) which the library will then use to show the actual resolution being used.

-The element `div-video-container` is used as the UI this div contains the video element for showing the video stream.
-
-   **NOTE**: The class name of the video element must be set to `dbrScanner-video`.
-
-   ```html
-   <video class="dbrScanner-video" playsinline="true"></video>
-   ```
-
-### Cameras and Resolution Options
-
-Next, you can add the camera list and resolution list.
-
-   If the class names match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution`, the library will automatically populate the lists and handle the camera/resolution switching automatically.
-
-```html
-<select class="dbrScanner-sel-camera"></select>
-```
-

-```
-   8 default resolutions are populated automatically.
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-The following code shows how to display a custom set of resolution options.
-
-```html
-<select class="dbrScanner-sel-resolution">
-    <option class="dbrScanner-opt-gotResolution" value="got"></option>
-    <option data-width="1920" data-height="1080">1920 x 1080</option>
-    <option data-width="1280" data-height="720">1280 x 720</option>
-    <option data-width="640" data-height="480">640 x 480</option>
-</select>
-```
-
-   **Possible Issue**: Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used.
-
-   **Solution**: Add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) which the library will then use to show the actual resolution being used.

-# Basic Customizations
-
-## Initializing
-
-The library is based on the `WebAssembly` standard; therefore, **on first use**, it needs some time to download and compile the `wasm` files. After first use, the browser may cache the file.
-
-`Dynamsoft.DBR.BarcodeReader.loadWasm()` is the API to start the initialization.
-
-```javascript
-try{
-    await Dynamsoft.DBR.BarcodeReader.loadWasm();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-Other APIs like `Dynamsoft.DBR.BarcodeReader.createInstance()` and `Dynamsoft.DBR.BarcodeScanner.createInstance()` will also call `loadWasm()` during initialization. The following demonstrates the most common usage. 
-
-```javascript
-let reader = null;
-let scanner = null;
-try{
-    reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-*NOTE*
-
-Including the library with a script tag doesn't automatically initialize the library. For better performance, you may want to call `loadWasm()` to download and compile the wasm file in advance and create a reader or scanner instance later.   
-
-Initialization consists of the following steps:
-
-* Download
-
-Download the necessary resources. Usually, we deploy the resources on CDN and set a long cache duration. *If your web server is faster, you should put the resources on your own server instead of using the CDN.*
-
-* Compile    
-    
-The `wasm` files are automatically compiled once downloaded. The compilation time varies among different devices & browsers. While it takes less than a second on latest phones or PCs, it may take much longer on older devices.
-
-* Initialize
-
-The library needs to initialize every time the page loads. The initialization means creating a `BarcodeReader` or `BarcodeScanner` instance with specified settings.
-
-## Configuring Scanner Settings
-
-When creating an instance of the `BarcodeScanner` object, there are several configuration options. The following code shows some of the most popular ones:
-
-```javascript
-// set which camera and what resolution to use
-await scanner.updateVideoSettings({ video: { width: 1280, height: 720, facingMode: "environment" } });
-
-// use one of the built-in RuntimeSetting templates: "single" (decode single barcode, default mode), "speed", "balance", "coverage". "speed" is recommended for decoding from a video stream
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code snippet below demonstrates how to specify which symbologies are enabled
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.EnumBarcodeFormat.BF_ONED | Dynamsoft.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period
-scanSettings.duplicateForgetTime = 20000;
-// set a scan interval so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see in the code, there are three types of configurations:
-
-- `get/updateVideoSettings`: Configures the data source, i.e., the video stream. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-- `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](../api-reference/global-interfaces.md#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-    ```javascript
-    await barcodeScanner.updateRuntimeSettings("speed");
-    //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-    //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-    let settings = await barcodeScanner.getRuntimeSettings();
-    settings.localizationModes = [
-        Dynamsoft.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-        Dynamsoft.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-        Dynamsoft.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0];
-    await barcodeScanner.updateRuntimeSettings(settings);
-    ```
-    Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-    
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`, `intervalTime` and `filter`, etc.
-
-## Customizing the UI
-
-The library provides a built-in UI for the `BarcodeScanner`object where the default scanner UI is defined in the file `dist/dbr.scanner.html`. There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you deploy these files yourself instead of using the CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and specify the new file as the default UI with the API `defaultUIElementURL`
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = url;
-  ```
-  
-  *Note*
-  
-  You must set `defaultUIElementURL` before you call `createInstance`.
-
-* Build the UI element into your own web page and call `scanner.setUIElement(HTMLElement)` to specify that element.
-* Append the default UI element to an element on your page. After that, you can customize it further. The following shows how to append the default UI to a DIV and hide the close button.
-  
-  ```html
-  <div id="scannerUI"></div>
-  ```
-  
-  ```javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true;
-  ```
-
-The following is an example of the 3rd option above. 
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <div id="div-video-container">
-        <video class="dbrScanner-video" playsinline="true"></video>

-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-*NOTE*
-
-The video element must contain the class `dbrScanner-video` so that it can be used.
-
-```html
-<video class="dbrScanner-video" playsinline="true"></video>
-```
-
-### Cameras and Resolution Options
-
-Next, you can add the camera list and resolution list inside the UI element. In our case, the element would be `document.getElementById('div-video-container')`.
-
-If the class names match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution`, the library will automatically populate the lists and handle the camera/resolution switching automatically.

-
-```html
-<select class="dbrScanner-sel-resolution"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-*Note*
-
-By default, 8 hard-coded resolutions will be populated as options.
-
-The following code shows how to display a custom set of resolution options.
-
-```html
-<select class="dbrScanner-sel-resolution">
-    <option class="dbrScanner-opt-gotResolution" value="got"></option>
-    <option data-width="1920" data-height="1080">1920 x 1080</option>
-    <option data-width="1280" data-height="720">1280 x 720</option>
-    <option data-width="640" data-height="480">640 x 480</option>
-</select>
-```
-
-*NOTE*
-
-Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-
-## Decode Barcodes from Existing Video Stream
-
-In v8.0, we introduced a new feature to decode barcodes from an existing video stream. To set the existing video stream, we'll use [setUIElement()](../api-reference/BarcodeScanner/methods/initialize-and-destroy.md#setuielement).
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <div id="div-video-container">
-        <video class="dbrScanner-existingVideo" src="myvideo.mp4"></video>
-    </div>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.0.0/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-    <script>
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-*NOTE*
-
-The video element must contain the class `dbrScanner-existingVideo`.

-The library is based on the `WebAssembly` standard; therefore, **on first use**, it needs some time to download and compile the `wasm` files. After first use, the browser may cache the file.
-
-`Dynamsoft.DBR.BarcodeReader.loadWasm()` is the API to start the initialization.
-
-```javascript
-try{
-    await Dynamsoft.DBR.BarcodeReader.loadWasm();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-Other APIs like `Dynamsoft.DBR.BarcodeReader.createInstance()` and `Dynamsoft.DBR.BarcodeScanner.createInstance()` will also call `loadWasm()` during initialization. The following demonstrates the most common usage. 
-
-```javascript
-let reader = null;
-let scanner = null;
-try{
-    reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-*NOTE*
-
-Including the library with a script tag doesn't automatically initialize the library. For better performance, you may want to call `loadWasm()` to download and compile the wasm file in advance and create a reader or scanner instance later.   
-
-Initialization consists of the following steps:
-
-* Download
-
-Download the necessary resources. Usually, we deploy the resources on CDN and set a long cache duration. *If your web server is faster, you should put the resources on your own server instead of using the CDN.*
-
-* Compile    
-    
-The `wasm` files are automatically compiled once downloaded. The compilation time varies among different devices & browsers. While it takes less than a second on latest phones or PCs, it may take much longer on older devices.
-
-* Initialize
-
-The library needs to initialize every time the page loads. The initialization means creating a `BarcodeReader` or `BarcodeScanner` instance with specified settings.
-
-## Configuring Scanner Settings
-
-When creating an instance of the `BarcodeScanner` object, there are several configuration options. The following code shows some of the most popular ones:
-
-```javascript
-// set which camera and what resolution to use
-await scanner.updateVideoSettings({ video: { width: 1280, height: 720, facingMode: "environment" } });
-
-// use one of the built-in RuntimeSetting templates: "single" (decode single barcode, default mode), "speed", "balance", "coverage". "speed" is recommended for decoding from a video stream
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code snippet below demonstrates how to specify which symbologies are enabled
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.EnumBarcodeFormat.BF_ONED | Dynamsoft.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period
-scanSettings.duplicateForgetTime = 20000;
-// set a scan interval so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see in the code, there are three types of configurations:
-
-- `get/updateVideoSettings`: Configures the data source, i.e., the video stream. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-- `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](../api-reference/global-interfaces.md#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-    ```javascript
-    await barcodeScanner.updateRuntimeSettings("speed");
-    //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-    //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-    let settings = await barcodeScanner.getRuntimeSettings();
-    settings.localizationModes = [
-        Dynamsoft.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-        Dynamsoft.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-        Dynamsoft.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0];
-    await barcodeScanner.updateRuntimeSettings(settings);
-    ```
-    Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-    
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`, `intervalTime` and `filter`, etc.
-
-## Customizing the UI
-
-The library provides a built-in UI for the `BarcodeScanner`object where the default scanner UI is defined in the file `dist/dbr.scanner.html`. There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you deploy these files yourself instead of using the CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and specify the new file as the default UI with the API `defaultUIElementURL`
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = url;
-  ```
-  
-  *Note*
-  
-  You must set `defaultUIElementURL` before you call `createInstance`.
-
-* Build the UI element into your own web page and call `scanner.setUIElement(HTMLElement)` to specify that element.
-* Append the default UI element to an element on your page. After that, you can customize it further. The following shows how to append the default UI to a DIV and hide the close button.
-  
-  ```html
-  <div id="scannerUI"></div>
-  ```
-  
-  ```javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true;
-  ```
-
-The following is an example of the 3rd option above. 
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <div id="div-video-container">
-        <video class="dbrScanner-video" playsinline="true"></video>
-    </div>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.1.2/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-    <script>
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-*NOTE*
-
-The video element must contain the class `dbrScanner-video` so that it can be used.
-
-```html
-<video class="dbrScanner-video" playsinline="true"></video>
-```
-
-### Cameras and Resolution Options
-
-Next, you can add the camera list and resolution list inside the UI element. In our case, the element would be `document.getElementById('div-video-container')`.
-
-If the class names match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution`, the library will automatically populate the lists and handle the camera/resolution switching automatically.
-
-```html
-<select class="dbrScanner-sel-camera"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-```html
-<select class="dbrScanner-sel-resolution"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-*Note*
-
-By default, 8 hard-coded resolutions will be populated as options.
-
-The following code shows how to display a custom set of resolution options.
-
-```html
-<select class="dbrScanner-sel-resolution">
-    <option class="dbrScanner-opt-gotResolution" value="got"></option>
-    <option data-width="1920" data-height="1080">1920 x 1080</option>
-    <option data-width="1280" data-height="720">1280 x 720</option>
-    <option data-width="640" data-height="480">640 x 480</option>
-</select>
-```
-
-*NOTE*
-
-Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-## Decode Barcodes from Existing Video Stream
-
-In v8.0, we introduced a new feature to decode barcodes from an existing video stream. To set the existing video stream, we'll use [setUIElement()](../api-reference/BarcodeScanner/methods/initialize-and-destroy.md#setuielement).
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <div id="div-video-container">

-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-*NOTE*
-
-The video element must contain the class `dbrScanner-existingVideo`.

-As you can see in the code, there are three types of configurations:
-
-- `get/updateVideoSettings`: Configures the data source, i.e., the video stream. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-- `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](../api-reference/global-interfaces.md#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-    ```javascript
-    await barcodeScanner.updateRuntimeSettings("speed");
-    //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-    //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative

-        Dynamsoft.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0];
-    await barcodeScanner.updateRuntimeSettings(settings);
-    ```
-    Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-    
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`, `intervalTime` and `filter`, etc.
-
-## Customizing the UI
-
-The library provides a built-in UI for the `BarcodeScanner`object where the default scanner UI is defined in the file `dist/dbr.scanner.html`. There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you deploy these files yourself instead of using the CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and specify the new file as the default UI with the API `defaultUIElementURL`
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = url;
-  ```
-  
-  *Note*
-  
-  You must set `defaultUIElementURL` before you call `createInstance`.
-
-* Build the UI element into your own web page and call `scanner.setUIElement(HTMLElement)` to specify that element.
-* Append the default UI element to an element on your page. After that, you can customize it further. The following shows how to append the default UI to a DIV and hide the close button.
-  
-  ```html
-  <div id="scannerUI"></div>
-  ```
-  
-  ```javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true;
-  ```
-
-The following is an example of the 3rd option above. 
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <div id="div-video-container">
-        <video class="dbrScanner-video" playsinline="true"></video>
-    </div>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->

-    <script>
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-*NOTE*
-
-The video element must contain the class `dbrScanner-video` so that it can be used.
-
-```html
-<video class="dbrScanner-video" playsinline="true"></video>
-```
-
-### Cameras and Resolution Options
-
-Next, you can add the camera list and resolution list inside the UI element. In our case, the element would be `document.getElementById('div-video-container')`.
-
-If the class names match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution`, the library will automatically populate the lists and handle the camera/resolution switching automatically.
-
-```html
-<select class="dbrScanner-sel-camera"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-```html
-<select class="dbrScanner-sel-resolution"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-*Note*
-
-By default, 8 hard-coded resolutions will be populated as options.
-
-The following code shows how to display a custom set of resolution options.
-
-```html
-<select class="dbrScanner-sel-resolution">
-    <option class="dbrScanner-opt-gotResolution" value="got"></option>
-    <option data-width="1920" data-height="1080">1920 x 1080</option>
-    <option data-width="1280" data-height="720">1280 x 720</option>
-    <option data-width="640" data-height="480">640 x 480</option>
-</select>
-```
-
-*NOTE*
-
-Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-## Decode Barcodes from Existing Video Stream
-
-In v8.0, we introduced a new feature to decode barcodes from an existing video stream. To set the existing video stream, we'll use [setUIElement()](../api-reference/BarcodeScanner/methods/initialize-and-destroy.md#setuielement).
-
-```html
-<!DOCTYPE html>

-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>

-</html>
-```
-*NOTE*
-
-The video element must contain the class `dbrScanner-existingVideo`.

-# Basic Customizations
-
-## Initializing
-
-The library is based on the `WebAssembly` standard; therefore, **on first use**, it needs some time to download and compile the `wasm` files. After first use, the browser may cache the file.
-
-`Dynamsoft.DBR.BarcodeReader.loadWasm()` is the API to start the initialization.
-
-```javascript
-try{
-    await Dynamsoft.DBR.BarcodeReader.loadWasm();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-Other APIs like `Dynamsoft.DBR.BarcodeReader.createInstance()` and `Dynamsoft.DBR.BarcodeScanner.createInstance()` will also call `loadWasm()` during initialization. The following demonstrates the most common usage. 
-
-```javascript
-let reader = null;
-let scanner = null;
-try{
-    reader = await Dynamsoft.DBR.BarcodeReader.createInstance();
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-}catch(ex){
-    console.error(ex);
-}
-```
-
-*NOTE*
-
-Including the library with a script tag doesn't automatically initialize the library. For better performance, you may want to call `loadWasm()` to download and compile the wasm file in advance and create a reader or scanner instance later.   
-
-Initialization consists of the following steps:
-
-* Download
-
-Download the necessary resources. Usually, we deploy the resources on CDN and set a long cache duration. *If your web server is faster, you should put the resources on your own server instead of using the CDN.*
-
-* Compile    
-    
-The `wasm` files are automatically compiled once downloaded. The compilation time varies among different devices & browsers. While it takes less than a second on latest phones or PCs, it may take much longer on older devices.
-
-* Initialize
-
-The library needs to initialize every time the page loads. The initialization means creating a `BarcodeReader` or `BarcodeScanner` instance with specified settings.
-
-## Configuring Scanner Settings
-
-When creating an instance of the `BarcodeScanner` object, there are several configuration options. The following code shows some of the most popular ones:
-
-```javascript
-// set which camera and what resolution to use
-await scanner.updateVideoSettings({ video: { width: 1280, height: 720, facingMode: "environment" } });
-
-// use one of the built-in RuntimeSetting templates: "single" (decode single barcode, default mode), "speed", "balance", "coverage". "speed" is recommended for decoding from a video stream
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code snippet below demonstrates how to specify which symbologies are enabled
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.EnumBarcodeFormat.BF_ONED | Dynamsoft.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period
-scanSettings.duplicateForgetTime = 20000;
-// set a scan interval so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```

-*NOTE*
-
-The video element must contain the class `dbrScanner-video` so that it can be used.
-
-```html
-<video class="dbrScanner-video" playsinline="true"></video>
-```
-
-### Cameras and Resolution Options
-
-Next, you can add the camera list and resolution list inside the UI element. In our case, the element would be `document.getElementById('div-video-container')`.
-
-If the class names match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution`, the library will automatically populate the lists and handle the camera/resolution switching automatically.
-
-```html
-<select class="dbrScanner-sel-camera"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-```html
-<select class="dbrScanner-sel-resolution"></select>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-*Note*
-
-By default, 8 hard-coded resolutions will be populated as options.
-
-The following code shows how to display a custom set of resolution options.
-
-```html
-<select class="dbrScanner-sel-resolution">
-    <option class="dbrScanner-opt-gotResolution" value="got"></option>
-    <option data-width="1920" data-height="1080">1920 x 1080</option>
-    <option data-width="1280" data-height="720">1280 x 720</option>
-    <option data-width="640" data-height="480">640 x 480</option>
-</select>
-```
-
-*NOTE*
-
-Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-## Decode Barcodes from Existing Video Stream
-
-In v8.0, we introduced a new feature to decode barcodes from an existing video stream. To set the existing video stream, we'll use [setUIElement()](../api-reference/BarcodeScanner/methods/initialize-and-destroy.md#setuielement).
-s
-```html
-<!DOCTYPE html>

-# Deployment Activation
-
-## Deployment: Self-hosted, Offline, or Intranet 
-
-The following steps guide you through how to deploy the library on your own server.
-
-### Step One: Deploy the dist folder
-
-Locate the **dist/** directory under the installation folder of the library and simply copy the entire directory to your server. The **dist/** folder should contain the following files:
-
-- `dbr.js` // For `<script>`
-- `dbr.browser.mjs` // For `<script type="module">`
-- `dbr.scanner.html` // Scanner default UI
-- `dbr-<version>.worker.js` // A worker thread for decoding
-- `dbr-<version>.wasm.js` // Compact Edition JS
-- `dbr-<version>.wasm` // Compact Edition WASM
-- `dbr-<version>.full.wasm.js` // Full Edition JS
-- `dbr-<version>.full.wasm` // Full Edition WASM
-
-If the resource files (e.g.,`wasm` files) are not placed in the same directory as `dbr.js`, you will need to specify the path using the API `engineResourcePath` before calling `loadWasm` or `createInstance`.
-
-```javascript
-Dynamsoft.BarcodeReader.engineResourcePath = "url/to/the/dir/";
-```
-
-### Step Two: Configure the Server
-
-Set the MIME type for `.wasm` to `application/wasm`.
-
-Different servers are configured differently. Here are some popular ones:
-
-- NGINX: `mime.types`
-- IIS: `Web.config`
-- Java™ EE web app: `web.xml`
-- Node.js: `npm mime`
-
-## License Activation
-
-A full license is required for deployment. If you have not purchased a license yet, please visit our [online store](https://www.dynamsoft.com/store/dynamsoft-barcode-reader/).

-# Deployment and Activation
-
-## Deployment: Self-hosted, Offline, or Intranet 
-
-The following steps guide you through how to deploy the library on your own server instead of using it via a CDN. If you just want to use it over CDN, check out [one-minute set-up]({{site.js }}user-guide/?ver=latest#step-one-write-the-code-in-one-minute).
-
-### Step One: Deploy the dist folder
-
-Locate the "dist/" directory under the installation folder of the library and copy the entire directory to your server.
-
-"dist/" folder should contain the following files and more:
-
-- `dbr.js` // For referencing the library with a `<script>` tag
-- `dbr.browser.mjs` // For using the library as a module (`<script type="module">`)
-- `dbr.scanner.html` // Defines the default scanner UI
-- `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-- `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-- `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-- `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-- `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-If the resource files (e.g.,`wasm` files) are not placed in the same directory as `dbr.js`, you will need to specify the path using the API `engineResourcePath` before calling `loadWasm()` or `createInstance()`. For example:
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.engineResourcePath = "url/to/the/dir/";
-```
-
-### Step Two: Configure the Server
-
-Set the MIME type for `.wasm` to `application/wasm`.
-
-Different servers are configured differently. Here are some popular ones:
-
-- NGINX: <a href="https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types" target="_blank">mime.types</a>
-- IIS: <a href="https://github.com/dynamsoft-dbr/javascript-barcode/blob/dac614f8033661901d85381dfaff8d612115862a/documents/conf/Web.config" target="_blank">Web.config</a>
-- Java™ EE web app: <a href="https://github.com/dynamsoft-dbr/javascript-barcode/blob/dac614f8033661901d85381dfaff8d612115862a/documents/conf/web.xml" target="_blank">web.xml</a>
-- Node.js: <a href="https://github.com/broofa/node-mime" target="_blank">npm mime</a>
-
-Please note that HTTPS **must** be enabled in order to use the component. For how to enable HTTPS, please check out the manual of your webserver.
-
-If deploying to a production server, it is recommended to use a valid SSL certificate.
-
-## License Activation
-
-Commercial deployment requires a full license. If you have not purchased a license yet, please visit our [online store](https://www.dynamsoft.com/store/dynamsoft-barcode-reader/).
-
-In version 8.0, we introduced [License Tracking 2.0](https://www.dynamsoft.com/license-tracking/docs/about/index.html) to activate and track usage. Please follow the steps in [this article](https://www.dynamsoft.com/license-tracking/docs/common/mechanism.html) to activate and use your license.

-### Supported Data Sources: 
-
-`Blob`, `HTMLImageElement`, `HTMLVideoElement`, and `URL`, etc.  
-
-### Compact and Full Editions  
-
-Two editions - Compact and Full - are available. The Compact Edition includes basic features with smaller size allowing for faster download and compiling. The Full Edition includes full features but with a larger size.
-
-The following table shows available features between the two editions:
-    
-  | Features | Compact edition | Full edition |
-  |:-:|:-:|:-:|
-  | `wasm` size<sup>1</sup>\(gzip\) | 810KB | 1.1 MB |
-  | 1D | &#10003; | &#10003; |
-  | QR | &#10003; | &#10003; |
-  | Micro QR | - | &#10003; |
-  | PDF417 | &#10003; | &#10003; |
-  | Micro PDF417 | - | &#10003; |
-  | DataMatrix | &#10003; | &#10003; |
-  | Aztec | - | &#10003; |
-  | MaxiCode | - | &#10003; |
-  | Patch Code | - | &#10003; |
-  | GS1 Composite Code | - | &#10003; |
-  | GS1 DataBar | - | &#10003; |
-  | DotCode | - | &#10003; |
-  | Postal Code | - | &#10003; |
-  | DPM | - | &#10003; |
-  | getRuntimeSettings | &#10003; | &#10003; |
-  | updateRuntimeSettings | &#10003; | &#10003; |
-  | getIntermediateResults | - | &#10003; |
-  | initRuntimeSettingsWithString | - | &#10003; |
-  | outputSettingsToString | - | &#10003; |
-  | **recommended scenario<sup>2</sup>** | Customer Facing Application | Enterprise Solution  |
-    
-<sup>1</sup> The `wasm` file size is of version 7.2.2. In later versions, the size may differ.  
-  
-<sup>2</sup> For the scenario where a user only needs to scan a barcode once, the Compact Edition is recommended as it downloads and compiles faster. For scenarios where a user needs to continuously scan many barcodes or where specific uncommon barcodes or advanced features are required, use the Full Edition by simply setting the following before you call `loadWasm` or `CreateInstance`.
-
-``` javascript
-Dynamsoft.BarcodeReader._bUseFullFeature = true;
-```
-
-## System Requirements
-
-This library requires some advanced features supported by all modern mainstream browsers:
-
-- WebAssembly, Blob, URL/`createObjectURL`, Web Workers  
-    
-    These four features are required for the library to work.
-
-- `MediaDevices`/`getUserMedia` 
-    
-    This is only required for in-browser video streaming. If a browser does not support this API, Single Frame Mode will be used automatically. If the API exists but doesn't work correctly, Single Frame Mode can be used as an alternative.  
-
-The following table is a list of supported browsers:  
-
-Browser Name | Version
-:-: | :-:
-Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-Edge<sup>2</sup> | v16+
-Safari<sup>3</sup> | v11+
-
-<sup>1</sup> On iOS, camera video streaming is only supported in Safari.  
-<sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library on the same domain as your webpage.  
-<sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-**NOTE**: Apart from the browsers, the operating systems running on the target devices may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.

For scenarios where a user needs to continuously scan many barcodes or where specific uncommon barcodes or advanced features are required, use the Full Edition by simply setting the following before you call `loadWasm()` or `CreateInstance()`.
-
-``` javascript
-Dynamsoft.DBR.BarcodeReader._bUseFullFeature = true;

-
-## System Requirements
-
-This library requires some advanced features supported by all modern mainstream browsers:
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`  
-    
-    These four features are required for the library to work.
-
-- `MediaDevices`/`getUserMedia` 
-    
-    This is only required for in-browser video streaming. If a browser does not support this API, "Single Frame Mode" will be used automatically. If the API exists but doesn't work correctly, "Single Frame Mode" can be used as an alternative.  
-
-The following table is a list of supported browsers:
-
-Browser Name | Version
-:-: | :-:
-Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-Edge<sup>2</sup> | v16+
-Safari<sup>3</sup> | v11+
-
-<sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-<sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library on the same domain as your webpage.  
-<sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-*NOTE*
-
-Apart from the browsers, the operating systems running on the target devices may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.

-# Dynamsoft Barcode Reader JavaScript Edition - User Guide
-
-![Dynamsoft JavaScript Barcode SDK](assets/dbr-js-sdk.png)  
-
-[Dynamsoft BarcodeReader SDK for Web](https://www.dynamsoft.com/Products/barcode-recognition-javascript.aspx) is a JavaScript SDK for barcode scanning based on **WebAssembly**. It supports real-time barcode localization and decoding of various barcode types. The library is capable of scanning barcodes directly from live video streams and static images. It also supports reading multiple barcodes at once.  
-
-In this guide, you will learn step by step how to use Dynamsoft Barcode Reader JavaScript Edition in your application:
-
-- [Getting Started](#getting-started---hello-world)
-- [Installation](#installation)
-- [Basic Customizations]({{ site.js }}user-guide/basic-customizations.html)
-- [Advanced Customizations]({{ site.js }}user-guide/advanced-customizations.html)
-- [Deployment Activation]({{ site.js }}user-guide/deployment-activation.html)
-- [Features Requirements]({{ site.js }}user-guide/features-requirements.html)
-- [Upgrade]({{ site.js }}user-guide/upgrade.html)
-
-
-## Getting Started - Hello World  
-
-Let's start by using the library to build a simple web application that will decode barcodes from a live video stream.  
-
-### Basic Requirements
-
-- Internet connection  
-- Supported Browser  
-- Camera access  
-
-### Step One: Write the code in one minute  
-
-Create an HTML file with the following content. Deploy this to your web server and run the application over **HTTPS**.
-
-- You will need to replace `PRODUCT-KEYS` with a trial key for the sample code to work correctly. You can acquire a trial key [here](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js).
-- If you don't have a ready-to-use web server but have a package manager like npm or yarn, you can set up a simple HTTP server in minutes. Check out `http-server` on npm or yarn.
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@7.5.0-v1/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-    <script>
-        // initializes and uses the library
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.BarcodeScanner.createInstance();
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-
-
-`onFrameRead`: This event is triggered after each single frame is scanned. The `results` object contains all the barcode results that the library found on this frame. In this example, we will print the results found in every frame to the console. 
-
-`onUnduplicatedRead`: This event is triggered when a new barcode (not a duplicate) is found. `txt` holds the barcode text value while `result` is an object that holds details of the found barcode. In this example, an alert will be displayed for each unique barcode found. 
-  
-
-### Step Two: Enable camera access
-
-Open the HTML page in your browser and you should see a pop-up asking for permission to access the camera. Once camera access is granted, the video stream will start in the default UI of the **BarcodeScanner** object.  
-
-**Note**: If you don't see the pop-up, wait a few seconds for the initialization to finish.   
-
-In this step, you might run into the following issues:
-
-#### getUserMedia non-HTTPS access issue
-
-If you open the HTML file as `file:///` or `http://`, the following error may appear in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-To access the camera with the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia), HTTPS is required.
-
-**Note**: If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-- NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-- IIS: [Create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-- Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)
-- Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-#### Self-signed certificate issue
-
-For testing purposes, a self-signed certificate can be used when configuring HTTPS. When accessing the site, the browser might say "the site is not secure". In this case, go to the certificate settings and set to trust this certificate.
-
-In a production environment, you will need a valid HTTPS certificate.
-
-### Step Three: Time to scan
-
-Place a barcode in front of the camera. You should see an alert pop up with the decoded barcode result and a coloured region on the video to highlight the barcode location.

-
-![Dynamsoft JavaScript Barcode SDK](assets/dbr-js-sdk.png)  
-
-[Dynamsoft BarcodeReader SDK for Web](https://www.dynamsoft.com/Products/barcode-recognition-javascript.aspx) is a JavaScript SDK for barcode scanning based on **WebAssembly**. It supports real-time barcode localization and decoding of various barcode types. The library is capable of scanning barcodes directly from live video streams and static images. It also supports reading multiple barcodes at once.  
-
-In this guide, you will learn step by step how to use Dynamsoft Barcode Reader JavaScript Edition in your application:
-
-- [Getting Started](#getting-started---hello-world)
-- [Installation](#installation)
-- [Basic Customizations]({{ site.js }}user-guide/basic-customizations.html)
-- [Advanced Customizations]({{ site.js }}user-guide/advanced-customizations.html)
-- [Deployment Activation]({{ site.js }}user-guide/deployment-activation.html)
-- [Features Requirements]({{ site.js }}user-guide/features-requirements.html)
-- [Upgrade]({{ site.js }}user-guide/upgrade.html)
-
-
-## Getting Started - Hello World  
-
-Let's start by using the library to build a simple web application that will decode barcodes from a live video stream.  
-
-### Basic Requirements
-
-- Internet connection  
-- Supported Browser  
-- Camera access  
-
-### Step One: Write the code in one minute  
-
-Create an HTML file with the following content. Deploy this to your web server and run the application over **HTTPS**.
-
-- You will need to replace `PRODUCT-KEYS` with a trial key for the sample code to work correctly. You can acquire a trial key [here](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js).
-- If you don't have a ready-to-use web server but have a package manager like npm or yarn, you can set up a simple HTTP server in minutes. Check out `http-server` on npm or yarn.
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.1.0/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-    <script>
-        // initializes and uses the library
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.BarcodeScanner.createInstance();
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-
-
-`onFrameRead`: This event is triggered after each single frame is scanned. The `results` object contains all the barcode results that the library found on this frame. In this example, we will print the results found in every frame to the console. 
-
-`onUnduplicatedRead`: This event is triggered when a new barcode (not a duplicate) is found. `txt` holds the barcode text value while `result` is an object that holds details of the found barcode. In this example, an alert will be displayed for each unique barcode found. 
-  
-
-### Step Two: Enable camera access
-
-Open the HTML page in your browser and you should see a pop-up asking for permission to access the camera. Once camera access is granted, the video stream will start in the default UI of the **BarcodeScanner** object.  
-
-**Note**: If you don't see the pop-up, wait a few seconds for the initialization to finish.   
-
-In this step, you might run into the following issues:
-
-#### getUserMedia non-HTTPS access issue
-
-If you open the HTML file as `file:///` or `http://`, the following error may appear in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-To access the camera with the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia), HTTPS is required.
-
-**Note**: If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-

-- Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-#### Self-signed certificate issue
-
-For testing purposes, a self-signed certificate can be used when configuring HTTPS. When accessing the site, the browser might say "the site is not secure". In this case, go to the certificate settings and set to trust this certificate.
-
-In a production environment, you will need a valid HTTPS certificate.
-
-### Step Three: Time to scan
-
-Place a barcode in front of the camera. You should see an alert pop up with the decoded barcode result and a coloured region on the video to highlight the barcode location.

-
-- `onFrameRead`: This event is triggered after the library finishes scanning a frame from the video stream. The `results` object contains all the barcode results that the library found on this frame. In this example, we print the results to the browser console.
-
-- `onUnduplicatedRead`: This event is triggered when a new barcode (not a duplicate) is found. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for each unique barcode found. Notice that if the same barcode is found on multiple consecutive frames, this event is only triggered once.

-*Note*:
-
-- The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like npm or yarn, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). However, for simple testing purposes, it's perfectly fine to just open the file directly from your local disk.
-
-- You will need to replace `PRODUCT-KEYS` with a trial key (or your Handshake Code if you have got one) for the sample code to work correctly. You can acquire a trial key [here](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js). Notice that the library will still read barcodes without a valid key (Code), but will return an annotated result string.
-
-- The library only scans a new frame when it has finished scanning the previous frame. Generally, frames come in faster than the library processes a frame (for 30 FPS, the interval is about 33 ms), therefore not all frames are scanned.
-
-### Step Two: Enable camera access
-
-Open the HTML page in your browser and you should see a pop-up asking for permission to access the camera. Once the access is granted, the video stream will start in the default UI of the **BarcodeScanner** object.

-
-![Dynamsoft JavaScript Barcode SDK](assets/dbr-js-sdk.png)  
-
-[Dynamsoft BarcodeReader SDK for Web](https://www.dynamsoft.com/Products/barcode-recognition-javascript.aspx) is a JavaScript SDK for barcode scanning based on **WebAssembly**. It supports real-time barcode localization and decoding of various barcode types. The library is capable of scanning barcodes directly from live video streams as well as static images. It also supports reading multiple barcodes at once.  
-
-In this guide, you will learn step by step how to use Dynamsoft Barcode Reader JavaScript Edition in your application:
-
-- [Getting Started](#getting-started---hello-world)
-- [Installation](#installation)
-- [Basic Customizations]({{ site.js }}user-guide/basic-customizations.html)
-- [Advanced Customizations]({{ site.js }}user-guide/advanced-customizations.html)
-- [Deployment Activation]({{ site.js }}user-guide/deployment-activation.html)
-- [Features Requirements]({{ site.js }}user-guide/features-requirements.html)
-- [Upgrade]({{ site.js }}user-guide/upgrade.html)
-
-
-## Getting Started - Hello World  
-
-Let's start by using the library to build a simple web application that will decode barcodes from a live video stream.  
-
-### Basic Requirements
-
-- Internet connection  
-- [Supported Browser]({{site.js}}user-guide/features-requirements.html#system-requirements)
-- Camera access  
-
-### Step One: Write the code in one minute  
-
-Creat a text file anywhere on your local disk and name it "helloworld.html". Copy the following content in the file and save. 
-
-```html
-<!DOCTYPE html>
-<html>
-<body>
-    <!-- Please visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to get a trial license. -->
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.0/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-    <script>
-        // initializes and uses the library
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            scanner.onFrameRead = results => {if(results.length > 0 ) console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-</body>
-</html>
-```
-
-*About the code*
-
-- `onFrameRead`: This event is triggered after the library finishes scanning a frame from the video stream. The `results` object contains all the barcode results that the library found on this frame. In this example, we print the results to the browser console.
-
-- `onUnduplicatedRead`: This event is triggered when a new barcode (not a duplicate) is found. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for each unique barcode found. Notice that if the same barcode is found on multiple consecutive frames, this event is only triggered once.
-
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-
-*Note*:
-
-- The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like npm or yarn, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). However, for simple testing purposes, it's perfectly fine to just open the file directly from your local disk.
-
-- You will need to replace `PRODUCT-KEYS` with a trial key (or your Handshake Code if you have got one) for the sample code to work correctly. You can acquire a trial key [here](https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js). Notice that the library will still read barcodes without a valid key (Code), but will return an annotated result string.
-
-- The library only scans a new frame when it has finished scanning the previous frame. Generally, frames come in faster than the library processes a frame (for 30 FPS, the interval is about 33 ms), therefore not all frames are scanned.
-
-### Step Two: Enable camera access
-
-Open the HTML page in your browser and you should see a pop-up asking for permission to access the camera. Once the access is granted, the video stream will start in the default UI of the **BarcodeScanner** object.  
-
-*Note*: 
-
-- If you don't see the pop-up, wait a few seconds for the initialization to finish.   
-
-In this step, you might run into the following issues:
-
-#### getUserMedia non-HTTPS access issue
-
-If you opened the HTML file as `file:///` or `http://`, the following error may appear in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because to access the camera with the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia), HTTPS is required.
-
-*Note*
-
-- If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-- NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-- IIS: [Create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-- Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)
-- Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-#### Self-signed certificate issue
-
-For testing purposes, a self-signed certificate can be used when configuring HTTPS. When accessing the site, the browser might say "the site is not secure". In this case, go to the certificate settings and trust this certificate.
-
-In a production environment, a valid HTTPS certificate is required.
-
-### Step Three: Time to scan
-
-Place a barcode in front of the camera. You should see an alert pop up with the decoded barcode result and a coloured region on the video to highlight the barcode location. 
-
-## Installation
-
-For evaluation purposes, we recommend that you get the official package of the library for developers. The following shows how to acquire the package.
-
-* From the website
-
-  [Download Dynamsoft Barcode Reader](https://www.dynamsoft.com/barcode-reader/downloads/)
-
-* yarn
-
-  ```
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ```
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-If you want to start building your application right away, you can also just make use of the library via CDN as shown in the previous helloworld sample code.
-
-* cdn
-
-  ```
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.0/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-  <!-- or -->
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.2.0/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-  ```
-
-Dynamsoft also provides a Barcode Reader SDK built for Node, see [Dynamsoft JavaScript Barcode SDK for Node](https://github.com/dynamsoft-dbr/node-javascript-barcode).

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection  
-  + [A supported browser](#system-requirements)
-  + Camera access  
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.5/dist/dbr.js"></script>
-  <script>
-        // initializes and uses the library
-        let scanner = null;
-        (async () => {
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            scanner.onFrameRead = results => {
-                if (results.length > 0) console.log(results);
-            };
-            scanner.onUnduplicatedRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a trial](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.5/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.2.5/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself (recommended)
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/DBR-JS-8.2.5/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-  The library requires a license to work, use the APIs `organizationID` and `handshakeCode` to specify how to acquire the license.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-  Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-  Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-  Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-LTS", "YOUR-OWN-STANDBY-LTS"]; //Optional, ignore this line if you are using Dynamsoft-hosting LTS.
-  ```
-
-  *Note*:
-
-  + Network connection is required for the license to work.
-  + If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-  + The license is actually fetched during the creation of an `BarcodeScanner` or `BarcodeReader` object.
-  + If a public network connection is not available, you can choose to host a license server in your private network.
-
-  An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/) for more information.
-  
-  ```javascript
-  Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-  ```
-  
-  Or
-  
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.5/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-  ```
-
-
-#### Specify the location of the "engine" files
-
-  The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-  The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-  ``` javascript
-  import DBR from "dynamsoft-javascript-barcode";
-  DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.2.5/dist/";
-  export default DBR;
-  ```
-
-#### Specify which engine to use
-
-  The library comes with two engines: "compact" and "full". They may be merged into one in the future, but right now you can choose one to use.
-
-  By default, the compact engine is used. The following line changes it to the full engine.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner._bUseFullFeature = true;
-  ```
-
-  The following table compares the features between the two engines:
-
-  | Features | Compact edition | Full edition |
-  |:-:|:-:|:-:|
-  | *.wasm* size<sup>*</sup>\(gzip\) | 897 KB | 1.2 MB |
-  | 1D | &#10003; | &#10003; |

-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in UI to allow barcode scanning via cameras. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-try {
-    await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from the License Tracking Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-await scanner.updateVideoSettings({
-    video: {
-        width: 1280,
-        height: 720,
-        facingMode: "environment"
-    }
-});
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period
-scanSettings.duplicateForgetTime = 20000;
-// set a scan interval so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, default mode), "speed", "balance", "coverage". "speed" is recommended for decoding from a video stream
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify which symbologies are enabled
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ``` html
-    <div id="div-video-container">
-        <video class="dbrScanner-video" playsinline="true" style="width:100%;height:100%;position:absolute;left:0;top:0;"></video>
-    </div>
-    <script>
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element must have the class `dbrScanner-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ``` html
-    <select class="dbrScanner-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ``` html
-    <select class="dbrScanner-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ``` html
-    <select class="dbrScanner-sel-resolution">
-        <option class="dbrScanner-opt-gotResolution" value="got"></option>
-        <option data-width="1920" data-height="1080">1920 x 1080</option>
-        <option data-width="1280" data-height="720">1280 x 720</option>
-        <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-Interested to test it further? Read on to learn how to request a 30-day free trial.
-
-## Requesting A Trial
-
-Since v8.2.5, a free public trial license is used by default if no license is specified.
-
-> Network connection is required for the free public trial license to work.
-
-After that, if you want to evaluate the library further, you can [register for a Dynamsoft account](https://www.dynamsoft.com/api-common/Regist/Regist) (if you haven't already done so) and request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-* If you like, you can also [contact our support team](https://www.dynamsoft.com/contact/) to get a trial extension.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`  
-    
-  These four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner/properties.html?ver=latest#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-Browser Name | Version
-:-: | :-:
-Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-Edge<sup>2</sup> | v16+
-Safari<sup>3</sup> | v11+
-
-<sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-<sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-
-<sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.browser.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` to `application/wasm`.
-
-  Different servers are configured differently. Here are some popular ones:
-

-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates are allowed during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to (specify the location of the "engine" files)[#specify-the-location-of-the-engine-files].
-
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/upgrade.html?ver=latest).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection  
-  + [A supported browser](#system-requirements)
-  + Camera access  
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.4.0/dist/dbr.js"></script>
-  <script>
-        // initializes and uses the library
-        let scanner = null;
-        (async () => {
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            scanner.onFrameRead = results => {
-                if (results.length > 0) console.log(results);
-            };
-            scanner.onUnduplicatedRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a trial](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.4.0/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.4.0/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself (recommended)
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/DBR-JS-8.4.0/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-  The library requires a license to work, use the APIs `organizationID` and `handshakeCode` to specify how to acquire the license.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-  Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-  Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-  Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-LTS", "YOUR-OWN-STANDBY-LTS"]; //Optional, ignore this line if you are using Dynamsoft-hosting LTS.
-  ```
-
-  *Note*:
-
-  + Network connection is required for the license to work.
-  + If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-  + The license is actually fetched during the creation of an `BarcodeScanner` or `BarcodeReader` object.
-  + If a public network connection is not available, you can choose to host a license server in your private network.
-
-  An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/) for more information.
-  
-  ```javascript
-  Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-  ```
-  
-  Or
-  
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.4.0/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-  ```
-
-
-#### Specify the location of the "engine" files
-
-  The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-  The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-  ``` javascript
-  import DBR from "dynamsoft-javascript-barcode";
-  DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.4.0/dist/";
-  export default DBR;
-  ```
-
-#### Specify which engine to use
-
-  The library comes with two engines: "compact" and "full". They may be merged into one in the future, but right now you can choose one to use.
-
-  By default, the compact engine is used. The following line changes it to the full engine.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner._bUseFullFeature = true;
-  ```
-
-  The following table compares the features between the two engines:
-
-  | Features | Compact edition | Full edition |
-  |:-:|:-:|:-:|
-  | *.wasm* size<sup>*</sup>\(gzip\) | 910 KB | 1.2 MB |
-  | 1D | &#10003; | &#10003; |

-  <sup>*</sup> The file size is version 8.4.0. In other versions, the size may be different.
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in UI to allow barcode scanning via cameras. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-try {
-    await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from the License Tracking Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-await scanner.updateVideoSettings({
-    video: {
-        width: 1280,
-        height: 720,
-        facingMode: "environment"
-    }
-});
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period
-scanSettings.duplicateForgetTime = 20000;
-// set a scan interval so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, default mode), "speed", "balance", "coverage". "speed" is recommended for decoding from a video stream
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify which symbologies are enabled
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ``` html
-    <div id="div-video-container">
-        <video class="dbrScanner-video" playsinline="true" style="width:100%;height:100%;position:absolute;left:0;top:0;"></video>
-    </div>
-    <script>
-        let scanner = null;
-        (async()=>{
-            scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {console.log(results);};
-            scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element must have the class `dbrScanner-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ``` html
-    <select class="dbrScanner-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ``` html
-    <select class="dbrScanner-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ``` html
-    <select class="dbrScanner-sel-resolution">
-        <option class="dbrScanner-opt-gotResolution" value="got"></option>
-        <option data-width="1920" data-height="1080">1920 x 1080</option>
-        <option data-width="1280" data-height="720">1280 x 720</option>
-        <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-After that, if you want to evaluate the library further, you can [register for a Dynamsoft account](https://www.dynamsoft.com/api-common/Regist/Regist) (if you haven't already done so) and request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-* If you like, you can also [contact our support team](https://www.dynamsoft.com/contact/) to get a trial extension.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`  
-    
-  These four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner/properties.html?ver=latest#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-Browser Name | Version
-:-: | :-:
-Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-Edge<sup>2</sup> | v16+
-Safari<sup>3</sup> | v11+
-
-<sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-<sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-
-<sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.browser.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` to `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for each document.
-
-  Different types of webservers are configured differently. Here are some popular ones:
-
-  + [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  + [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  + [NGINX](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates are allowed during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to (specify the location of the "engine" files)[#specify-the-location-of-the-engine-files].
-
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/upgrade.html?ver=latest).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection  
-  + [A supported browser](#system-requirements)
-  + Camera access  
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.0/dist/dbr.js"></script>
-  <script>
-    // initializes and uses the library
-    (async () => {
-      let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-      scanner.onFrameRead = results => {
-        if (results.length > 0) console.log(results);
-      };
-      scanner.onUnduplicatedRead = (txt, result) => {
-        alert(txt);
-      };
-      await scanner.show();
-    })();
-  </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example - online](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a private trial license](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/?utm_source=github).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.0/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.6.0/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself (recommended)
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=github)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/DBR-JS-8.6.0/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the APIs `organizationID` and `handshakeCode` to specify how to acquire the license.
-
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-DLS", "YOUR-OWN-STANDBY-DLS"]; //Optional, ignore this line if you are using Dynamsoft-hosting DLS.
-  ```
-
-*Note*:
-
-+ Network connection is required for the license to work.
-+ If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-+ The license is actually fetched during the creation of a `BarcodeScanner` or `BarcodeReader` instance.
-+ If a public network connection is not available, you can choose to host a license server in your private network.
-
-An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/?utm_source=github) for more information.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-```
-  
-Or
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.0/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-```
-
-#### Specify the location of the "engine" files
-
-The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-``` javascript
-import DBR from "dynamsoft-javascript-barcode";
-DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.0/dist/";
-export default DBR;
-```
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-try {
-  await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-  console.error(ex);
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from Dynamsoft License Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-var allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage".
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html#runtimesettings?utm_source=github). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=latest&utm_source=github).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ``` html
-    <div id="div-video-container">
-      <video class="dbrScanner-video" playsinline="true" style="width:100%;height:100%;position:absolute;left:0;top:0;"></video>
-    </div>
-    <script>
-      (async()=>{
-        let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-        await scanner.setUIElement(document.getElementById('div-video-container'));
-        scanner.onFrameRead = results => {console.log(results);};
-        scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-        await scanner.show();
-      })();
-    </script>
-    ```
-
-    > The video element must have the class `dbrScanner-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ``` html
-    <select class="dbrScanner-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ``` html
-    <select class="dbrScanner-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ``` html
-    <select class="dbrScanner-sel-resolution">
-      <option class="dbrScanner-opt-gotResolution" value="got"></option>
-      <option data-width="1920" data-height="1080">1920 x 1080</option>
-      <option data-width="1280" data-height="720">1280 x 720</option>
-      <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-Interested to test it further? Read on to learn how to request a 30-day free trial.
-
-## Requesting A Trial
-
-Since v8.2.5, a free public trial license is used by default if no license is specified.
-
-> Network connection is required for the free public trial license to work.
-
-After that, if you want to evaluate the library further, you can [register for a Dynamsoft account](https://www.dynamsoft.com/api-common/Regist/Regist) (if you haven't already done so) and request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-* If you like, you can also [contact our support team](https://www.dynamsoft.com/contact/?utm_source=github) to get a trial license.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`  
-    
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner/properties.html?ver=latest&utm_source=github#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.browser.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  + [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  + [NGINX](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates are allowed during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to (specify the location of the "engine" files)[#specify-the-location-of-the-engine-files].
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest&utm_source=github).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=latest&utm_source=github).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection  
-  + [A supported browser](#system-requirements)
-  + Camera access  
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.3/dist/dbr.js"></script>
-  <script>
-    // initializes and uses the library
-    (async () => {
-      let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-      scanner.onFrameRead = results => {
-        if (results.length > 0) console.log(results);
-      };
-      scanner.onUnduplicatedRead = (txt, result) => {
-        alert(txt);
-      };
-      await scanner.show();
-    })();
-  </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example - online](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a private trial license](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/?utm_source=github).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.3/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.6.3/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself (recommended)
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=github)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/DBR-JS-8.6.3/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the APIs `organizationID` and `handshakeCode` to specify how to acquire the license.
-
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-DLS", "YOUR-OWN-STANDBY-DLS"]; //Optional, ignore this line if you are using Dynamsoft-hosting DLS.
-  ```
-
-*Note*:
-
-+ Network connection is required for the license to work.
-+ If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-+ The license is actually fetched during the creation of a `BarcodeScanner` or `BarcodeReader` instance.
-+ If a public network connection is not available, you can choose to host a license server in your private network.
-
-An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/?utm_source=github) for more information.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-```
-  
-Or
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.3/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-```
-
-#### Specify the location of the "engine" files
-
-The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-``` javascript
-import DBR from "dynamsoft-javascript-barcode";
-DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.6.3/dist/";
-export default DBR;
-```
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-try {
-  await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-  console.error(ex);
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from Dynamsoft License Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-var allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage".
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html#runtimesettings?utm_source=github). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=latest&utm_source=github).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ``` html
-    <div id="div-video-container">
-      <video class="dbrScanner-video" playsinline="true" style="width:100%;height:100%;position:absolute;left:0;top:0;"></video>
-    </div>
-    <script>
-      (async()=>{
-        let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-        await scanner.setUIElement(document.getElementById('div-video-container'));
-        scanner.onFrameRead = results => {console.log(results);};
-        scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-        await scanner.show();
-      })();
-    </script>
-    ```
-
-    > The video element must have the class `dbrScanner-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ``` html
-    <select class="dbrScanner-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ``` html
-    <select class="dbrScanner-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ``` html
-    <select class="dbrScanner-sel-resolution">
-      <option class="dbrScanner-opt-gotResolution" value="got"></option>

-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-Interested to test it further? Read on to learn how to request a 30-day free trial.
-
-## Requesting A Trial
-
-Since v8.2.5, a free public trial license is used by default if no license is specified.
-
-> Network connection is required for the free public trial license to work.
-
-After that, if you want to evaluate the library further, you can [register for a Dynamsoft account](https://www.dynamsoft.com/api-common/Regist/Regist) (if you haven't already done so) and request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-* If you like, you can also [contact our support team](https://www.dynamsoft.com/contact/?utm_source=github) to get a trial license.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`  
-    
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner/properties.html?ver=latest&utm_source=github#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.browser.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  + [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  + [NGINX](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates are allowed during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to [specify the location of the "engine" files](#specify-the-location-of-the-engine-files).
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest&utm_source=github).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=latest&utm_source=github).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection  
-  + [A supported browser](#system-requirements)
-  + Camera access  
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.0/dist/dbr.js"></script>
-  <script>
-    // initializes and uses the library
-    (async () => {
-      let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-      scanner.onFrameRead = results => {
-        if (results.length > 0) console.log(results);
-      };
-      scanner.onUnduplicatedRead = (txt, result) => {
-        alert(txt);
-      };
-      await scanner.show();
-    })();
-  </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example - online](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a private trial license](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/?utm_source=github).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.0/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.8.0/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself (recommended)
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=github)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/DBR-JS-8.8.0/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the APIs `organizationID` and `handshakeCode` to specify how to acquire the license.
-
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-DLS", "YOUR-OWN-STANDBY-DLS"]; //Optional, ignore this line if you are using Dynamsoft-hosting DLS.
-  ```
-
-*Note*:
-
-+ Network connection is required for the license to work.
-+ If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-+ The license is actually fetched during the creation of a `BarcodeScanner` or `BarcodeReader` instance.
-+ If a public network connection is not available, you can choose to host a license server in your private network.
-
-An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/?utm_source=github) for more information.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-```
-  
-Or
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.0/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-```
-
-#### Specify the location of the "engine" files
-
-The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-``` javascript
-import DBR from "dynamsoft-javascript-barcode";
-DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.0/dist/";
-export default DBR;
-```
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-try {
-  await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-  console.error(ex);
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from Dynamsoft License Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-var allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage".
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html#runtimesettings?utm_source=github). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=latest&utm_source=github).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ``` html
-    <div id="div-video-container">
-      <video class="dbrScanner-video" playsinline="true" style="width:100%;height:100%;position:absolute;left:0;top:0;"></video>
-    </div>
-    <script>
-      (async()=>{
-        let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-        await scanner.setUIElement(document.getElementById('div-video-container'));
-        scanner.onFrameRead = results => {console.log(results);};
-        scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-        await scanner.show();
-      })();
-    </script>
-    ```
-
-    > The video element must have the class `dbrScanner-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ``` html
-    <select class="dbrScanner-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ``` html
-    <select class="dbrScanner-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ``` html
-    <select class="dbrScanner-sel-resolution">
-      <option class="dbrScanner-opt-gotResolution" value="got"></option>
-      <option data-width="1920" data-height="1080">1920 x 1080</option>
-      <option data-width="1280" data-height="720">1280 x 720</option>
-      <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-Interested to test it further? Read on to learn how to request a 30-day free trial.
-
-## Requesting A Trial
-
-Since v8.2.5, a free public trial license is used by default if no license is specified.
-
-> Network connection is required for the free public trial license to work.
-
-After that, if you want to evaluate the library further, you can [register for a Dynamsoft account](https://www.dynamsoft.com/api-common/Regist/Regist) (if you haven't already done so) and request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-* If you like, you can also [contact our support team](https://www.dynamsoft.com/contact/?utm_source=github) to get a trial license.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`  
-    
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner/properties.html?ver=latest&utm_source=github#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.browser.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  + [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  + [NGINX](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates are allowed during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to [specify the location of the "engine" files](#specify-the-location-of-the-engine-files).
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest&utm_source=github).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=latest&utm_source=github).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection
-  + [A supported browser](#system-requirements)
-  + Camera access
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.3/dist/dbr.js"></script>
-  <script>
-    // initializes and uses the library
-    (async () => {
-      let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-      scanner.onFrameRead = results => {
-        if (results.length > 0) console.log(results);
-      };
-      scanner.onUnduplicatedRead = (txt, result) => {
-        alert(txt);
-      };
-      await scanner.show();
-    })();
-  </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html?utm_source=guide).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example - online](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html?utm_source=guide) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a private trial license](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/?utm_source=guide).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.3/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.8.3/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=guide)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/dbr-js-8.8.3/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the APIs `organizationID` and / or `handshakeCode` to specify how to acquire the license.
-
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-DLS", "YOUR-OWN-STANDBY-DLS"]; //Optional, ignore this line if you are using Dynamsoft-hosting DLS.
-```
-
-*Note*:
-
-+ Network connection is required for the license to work.
-+ If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-+ The license is actually fetched during the creation of a `BarcodeScanner` or `BarcodeReader` instance.
-+ If a public network connection is not available, you can choose to host a license server in your private network. [Contact us](https://www.dynamsoft.com/contact/?utm_source=guide) for more information.
-
-An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/?utm_source=guide) for more information.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-```
-  
-Or
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.3/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-```
-
-#### Specify the location of the "engine" files
-
-The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.3/dist/";
-```
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-let scanner = null;
-try {
-  scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-  console.error(ex);
-}
-```
-
-When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-``` javascript
-let scanner = null, pScanner = null;
-function createBarcodeScanner(){
-  try {
-    scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-  } catch (ex) {
-    console.error(ex);
-  }
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from Dynamsoft License Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-var allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage"
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html?utm_source=guide#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=latest&utm_source=guide).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-

-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.

-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-
-## Requesting a Trial
-
-You can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link. Or you can [contact our support team](https://www.dynamsoft.com/contact/?utm_source=github) to get a free trial license.
-
-Since v8.2.5, a free public trial license is used by default if no license is specified.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`, `import`
-    
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=latest&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-  
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  + [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  + [NGINX](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates can be used during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to [specify the location of the "engine" files](#specify-the-location-of-the-engine-files).
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest&utm_source=guide).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=latest&utm_source=guide).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-  - NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-  - IIS: [Create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-  - Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)
-  - Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-### Accounting for newline characters in the barcode result
-When it comes to HTML, newline characters (`\n`) are not interpreted as they normally would. Therefore, if a barcode result contains a newline character, and you display the result in an alert box or some other text element, then the newline character will most probably be ignored.
-
-There are two ways in which you can resolve this:
-1. Wrap the element used to display the result in a `<pre>` element.
-2. Manually replace each `\n` character in the result with `<br \>`

-## Hello World - Simplest Implementation
-
-Let's start by testing the "Hello World" example of the library which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  + Internet connection
-  + [A supported browser](#system-requirements)
-  + Camera access
-
-### Step One: Check the code of the example
-
-The complete code of the "Hello World" example is shown below
-
-``` html
-<!DOCTYPE html>
-<html>
-
-<body>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.5/dist/dbr.js"></script>
-  <script>
-    // initializes and uses the library
-    (async () => {
-      let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-      scanner.onFrameRead = results => {
-        if (results.length > 0) console.log(results);
-      };
-      scanner.onUnduplicatedRead = (txt, result) => {
-        alert(txt);
-      };
-      await scanner.show();
-    })();
-  </script>
-</body>
-
-</html>
-```
-
-> You can also find the code (with more comments) [on GitHub](https://github.com/Dynamsoft/barcode-reader-javascript-samples/blob/master/1.hello-world/1.minimum-code.html?utm_source=guide).
-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the [MediaDevices interface](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices).
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Step Two: Test the example
-
-You can choose one of three ways to test the example:
-
-* [Hello World example - online](https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.minimum-code.html?utm_source=guide) 
-* [Hello World example via JSFiddle](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/)
-* [Download a copy](https://tst.dynamsoft.com/public/download/dbr/browser/code/helloworld.zip) of the example code and set it up locally
-
-Either way, you open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at something with a barcode to read it.
-
-If the barcode is decoded, an alert will pop up with the result text. At the same time, the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library only scans a new frame when it has finished scanning the previous frame. The interval between two consecutive frames might not be enough time for the library to process the 1st frame (for 30 FPS, the interval is about 33 ms), therefore, not all frames are scanned.
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a private trial license](#requesting-a-trial).
-
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/?utm_source=guide).
-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ``` html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.5/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ``` html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.8.5/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-The following shows a few ways to download the library.
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=guide)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ``` 
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it. You can typically include it like this:
-
-``` html
-<script src="/dbr-js-8.8.5/dist/dbr.js"></script>
-```
-
-or
-
-``` html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the APIs `organizationID` and / or `handshakeCode` to specify how to acquire the license.
-
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.organizationID = "YOUR-ORGANIZATION-ID"; // Required.
-Dynamsoft.DBR.BarcodeScanner.handshakeCode = "A-SPECIFIC-HANDSHAKECODE"; // Optional, if not specified, the default handshake code is used.
-Dynamsoft.DBR.BarcodeScanner.sessionPassword = "PASSWORD-TO-PROTECT-YOUR-LICENSE"; // Optional but recomended, use it to protect your license.
-Dynamsoft.DBR.BarcodeScanner.licenseServer = ["YOUR-OWN-MAIN-DLS", "YOUR-OWN-STANDBY-DLS"]; //Optional, ignore this line if you are using Dynamsoft-hosting DLS.
-```
-
-*Note*:
-
-+ Network connection is required for the license to work.
-+ If nothing is specified like the above "hello world" example, a [free public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. 
-+ The license is actually fetched during the creation of a `BarcodeScanner` or `BarcodeReader` instance.
-+ If a public network connection is not available, you can choose to host a license server in your private network. [Contact us](https://www.dynamsoft.com/contact/?utm_source=guide) for more information.
-
-An alternative way to specify the license is to use an alphanumeric string which does not require a network connection. The following shows how it could be used. [Contact us](https://www.dynamsoft.com/contact/?utm_source=guide) for more information.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.productKeys = "t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."
-```
-  
-Or
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.5/dist/dbr.js" data-productKeys="t0068NQAAACgTVU2aucyxqETXKkiomqhV7YoLrnqjLiQQRSH5DBV1UtIs4..."></script>
-```
-
-#### Specify the location of the "engine" files
-
-The "engine" files refer to *.worker.js, *.wasm.js and *.wasm, etc. which are loaded by the main library at runtime. This configuration option uses the API `engineResourcePath` and is often not required as these files usually are in the same location with the main library file (dbr.js). However, in cases where the engine files are not in the same location as the main library file (for example, with frameworks like Angular or React, dbr.js is compiled into another file), this configuration will be required.
-
-The following code uses the jsDelivr CDN, feel free to change it to your own location of these files.
-  
-``` javascript
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.5/dist/";
-```
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-``` javascript
-let scanner = null;
-try {
-  scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-  console.error(ex);
-}
-```
-
-When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-``` javascript
-let scanner = null, pScanner = null;
-function createBarcodeScanner(){
-  try {
-    scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-  } catch (ex) {
-    console.error(ex);
-  }
-}
-```
-
-*Note*:
-
-* The creation of an object consists of two parallel tasks: one is to download and compile the "engine", the other is to fetch a license from Dynamsoft License Server (assuming an online license is used).
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-``` javascript
-// set which camera and what resolution to use
-var allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-``` javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-scanSettings.intervalTime = 300;
-await scanner.updateScanSettings(scanSettings);
-```
-
-``` javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage"
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more [here](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax).
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine. Find a full list of these settings and their corresponding descriptions [here](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html?utm_source=guide#runtimesettings). For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ``` javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative

-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ``` javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ``` html
-  <div id="scannerUI"></div>
-  ```
-
-  ``` javascript
-  document.getElementById('scannerUI').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dbrScanner-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ``` html
-    <div id="div-video-container">
-      <video class="dbrScanner-video" playsinline="true" style="width:100%;height:100%;position:absolute;left:0;top:0;"></video>
-    </div>
-    <script>
-      (async()=>{
-        let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-        await scanner.setUIElement(document.getElementById('div-video-container'));
-        scanner.onFrameRead = results => {console.log(results);};
-        scanner.onUnduplicatedRead = (txt, result) => {alert(txt);};
-        await scanner.show();
-      })();
-    </script>
-    ```
-
-    > The video element must have the class `dbrScanner-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-  
-    If the class names for these lists match the default ones, `dbrScanner-sel-camera` and `dbrScanner-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ``` html
-    <select class="dbrScanner-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ``` html
-    <select class="dbrScanner-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ``` html
-    <select class="dbrScanner-sel-resolution">
-      <option class="dbrScanner-opt-gotResolution" value="got"></option>
-      <option data-width="1920" data-height="1080">1920 x 1080</option>
-      <option data-width="1280" data-height="720">1280 x 720</option>
-      <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dbrScanner-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-Interested to test it further? Read on to learn how to request a 30-day free trial.
-
-## Requesting a Trial
-
-You can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link. Or you can [contact our support team](https://www.dynamsoft.com/contact/?utm_source=github) to get a free trial license.
-
-Since v8.2.5, a free public trial license is used by default if no license is specified.
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`, `import`
-    
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia` 
-    
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=latest&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly,  the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-  
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-     
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Hosting the library
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). The following shows some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  + [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  + [NGINX](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* Enable HTTPS
-
-  To use the library, you must access your website / web application via a secure HTTPS connection. This is due to browser security restrictions which only grant camera video streaming access to a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).
-
-  > For convenience, self-signed certificates can be used during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-``` html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to [specify the location of the "engine" files](#specify-the-location-of-the-engine-files).
-
-## Advanced Usage
-
-In addition to the content mentioned above, the library has many other settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=latest&utm_source=guide).
-
-## How to Upgrade
-
-If you are using an older version of the library and want to upgrade it to the latest version, please read more on [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=latest&utm_source=guide).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server) or [yarn](https://yarnpkg.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://`, the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API [getUserMedia](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-  - NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-  - IIS: [Create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-  - Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)
-  - Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-### Accounting for newline characters in the barcode result
-When it comes to HTML, newline characters (`\n`) are not interpreted as they normally would. Therefore, if a barcode result contains a newline character, and you display the result in an alert box or some other text element, then the newline character will most probably be ignored.
-
-There are two ways in which you can resolve this:
-1. Wrap the element used to display the result in a `<pre>` element.
-2. Manually replace each `\n` character in the result with `<br \>`

-
-*About the code*
-
-  + `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-  + `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-  + `onUnduplicatedRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-  + `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Step Two: Test the example
-
-Open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed. 
-
-  > For first use, you may need to wait a few seconds for the library to initialize.
-
-*Note*:
-
-  + The library requires a license to work. However, when no license is specified in the code, a [free 1-day public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will automatically be used during which you can make initial evaluation of the library to decide whether or not you want to evaluate it further. If you do, you can [request a 30-day private trial license](#requesting-a-trial).
-    > Network connection is required for the free public trial license to work.
-
-If the test doesn't go as expected, you can check out the [FAQ](#faq) or [contact us](https://www.dynamsoft.com/contact/?utm_source=guide).

-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.7/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@8.8.7/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-A few ways to download the library:
-
-* From the website
-
-  [Download the JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=guide)
-
-* yarn
-
-  ```cmd
-  $ yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ```
-  $ npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it, you can typically include it like this:
-
-```html
-<script src="/dbr-js-8.8.7/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](#hosting-the-library-optional).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the API `license` to specify it.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader.license =
-  "YOUR-ORGANIZATION-ID or YOUR-HANDSHAKECODE or AN-OFFLINE-LICENSE or ANY-OTHER-TYPE-OF-SUPPORTED-LICENSE-STRING";
-```
-  
-Or
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.7/dist/dbr.js"
-  data-license="YOUR-ORGANIZATION-ID or YOUR-HANDSHAKECODE or AN-OFFLINE-LICENSE or ANY-OTHER-TYPE-OF-SUPPORTED-LICENSE-STRING"></script>
-```
-
-*Note*:
-
-* When specified by YOUR-ORGANIZATION-ID or YOUR-HANDSHAKECODE, the license is an online license and a network connection to Dynamsoft License Server is required for it to work.
-* In most cases, online licenses are offered. If you want to use an offline license, you can [contact us](https://www.dynamsoft.com/contact/?utm_source=guide).
-* If nothing is specified like the above "hello world" example, a [free 1-day public trial license](https://www.dynamsoft.com/license-server/docs/about/terms.html?ver=latest#public-trial-license?utm_source=guide) will be automatically used. This license requires a network connection.
-  
-
-#### Specify the location of the "engine" files
-
-If the engine files (*.worker.js, *.wasm.js and *.wasm, etc.) are not in the same location with the main library file (dbr.js), you can use the API `engineResourcePath` to specify the engine path, for example:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.7/dist/";
-```
-
-This configuration is usually required with frameworks like Angular or React where dbr.js is compiled into another file.
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner`, on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-```javascript
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets first:
-
-```javascript
-// set which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-scanSettings.intervalTime = 100;
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage"
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime`,  `intervalTime` and `filter`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-> Find the full list of these settings <a href="https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html?utm_source=guide#runtimesettings" target="_blank" title="here">here</a>. 
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=8.8.7&utm_source=guide).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.scanner.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.scanner.html` directly. 
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.scanner.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-video-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-video-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  + Embed the video
-
-    ```html
-    <div id="div-video-container" style="position:relative;width:100%;height:70vh;">
-        <video class="dce-video" playsinline="true" muted style="position:absolute;left:0;top:0;width:100%;height:100%;"></video>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-video-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUnduplicatedRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element must have the class `dce-video` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  + Add the camera list and resolution list
-  
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <select class="dce-sel-camera" style="position:absolute;left:0;top:0;"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <select class="dce-sel-resolution" style="position:absolute;left:0;top:20px;"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ```html
-    <select class="dce-sel-resolution" style="position:absolute;left:0;top:20px;">
-        <option class="dce-opt-gotResolution" value="got"></option>
-        <option data-width="1920" data-height="1080">1920 x 1080</option>
-        <option data-width="1280" data-height="720">1280 x 720</option>
-        <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`,  `Blob`,  `URL`/`createObjectURL`,  `Web Workers`
-    
-
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=8.8.7&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v57+ (v59+ on Android/iOS<sup>1</sup>)
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page. 
-  
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-<br>
-
-## Hosting the library (optional)
-
-### Step One: Deploy the dist folder
-
-Once you have downloaded the library, you can locate the "dist" directory and copy it to your server (usually as part of your website / web application). 
-
-Some of the files in this directory:
-
-* `dbr.js` // The main library file
-* `dbr.mjs` // For using the library as a module (`<script type="module">`)
-* `dbr.scanner.html` // Defines the default scanner UI
-* `dbr-<version>.worker.js` // Defines the worker thread for barcode reading
-* `dbr-<version>.wasm.js` // Compact edition of the library (.js)
-* `dbr-<version>.wasm` // Compact edition of the library (.wasm)
-* `dbr-<version>.full.wasm.js` // Full edition of the library (.js)
-* `dbr-<version>.full.wasm` // Full edition of the library (.wasm)
-
-### Step Two: Configure the Server
-
-* Set the MIME type for `.wasm` as `application/wasm` on your webserver.
-  
-  The goal is to configure your server to send the correct Content-Type header for the wasm file so that it is processed correctly by the browser.
-
-  Different types of webservers are configured differently, for example:
-
-  + <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings" title="Apache">Apache</a>
-  + <a target="_blank" href="https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap" title="IIS">IIS</a>
-  + <a target="_blank" href="https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types" title="NGINX">NGINX</a>
-
-* Enable HTTPS
-
-  Due to the browser <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts" title="security restriction">security restriction</a> on camera video streaming access, a secure HTTPS connection is required to use the library with camera.
-
-  > For convenience, self-signed certificates can be used during development and testing.
-
-### Step Three: Include the library from the server
-
-Now that the library is hosted on your server, you can include it accordingly.
-
-```html
-<script src="https://www.yourwebsite.com/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Optionally, you may also need to [specify the location of the "engine" files](#specify-the-location-of-the-engine-files).
-
-<br>
-
-## Advanced Usage
-
-In addition to the above basic settings, the library has many more settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=8.8.7&utm_source=guide).
-
-<br>
-
-## How to Upgrade
-
-If you want to upgrade the library from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=8.8.7&utm_source=guide).
-

-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server). 
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://` , the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
-
-* In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> requires HTTPS to access the camera.
-
-* If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via file:/// and http://localhost.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-### Accounting for newline characters in the barcode result
-
-When it comes to HTML, newline characters ( `\n` ) are not interpreted as they normally would. Therefore, if a barcode result contains a newline character, and you display the result in an modal dialogue box or some other text elements, then the newline character will probably be ignored.
-
-There are two ways in which you can resolve this:
-1. Wrap the element used to display the result in a `<pre>` element.
-2. Manually replace each `\n` character in the result with `<br>`

-#### About the code
-
-* `license`: This property specifies a license key. Read more on [Specify the license](#specify-the-license).
-
-* `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-* `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-* `onUniqueRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-* `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Step Two: Test the example
-
-Open the example page in a browser, allow the page to access your camera and the video will show up on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-*Note*:
-
-* Although the page should work properly when opened directly as a file ("file:///"), it's recommended that you deploy it to a web server before accessing it. Also, some browsers require a secure connection (HTTPS) to access the cameras, so deploying the page to a HTTPS website is the best choice.
-* For first use, you may need to wait a few seconds for the library to initialize.
-* The license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this sample is an online license and requires network connection to work.
-

-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.0/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.0.0/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-To download the library:
-
-* yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it, you can typically include it like this:
-
-```html
-<script src="/dbr-js-9.0.0/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](advanced-usage.md#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the library, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you registered for a Dynamsoft account and downloaded the library from the official site, Dynamsoft will generate a 30-day trial license for you and put the license key in all the downloaded samples.
-
-#### Specify the location of the "engine" files
-
-If the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.) are not in the same location with the main library file (dbr.js), you can use the API `engineResourcePath` to specify the engine path, for example:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.0/dist/";
-```
-
-This configuration is usually required with frameworks like Angular or React where dbr.js is compiled into another file.
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner`, on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Configure the `BarcodeScanner` object
-
-Let's take a look at the following code snippets:
-
-```javascript
-// set which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// set up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// disregard duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// set a scan interval in milliseconds so the library may release the CPU from time to time
-// setting this value larger is also a simple way to save battery power and reduce device heating.
-scanSettings.intervalTime = 100;
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// use one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage"
-await scanner.updateRuntimeSettings("speed");
-
-// make changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* `get/updateVideoSettings`: Configures the data source, i.e., the camera. These settings include which camera to use, the resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-> Find the full list of the runtime settings <a href="https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html?utm_source=guide#runtimesettings" target="_blank" title="here">here</a>.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=9.0.0&utm_source=guide).
-
-#### Customize the UI
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.ui.html` directly.
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  * Embed the video
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-ui-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element will be created and appended to the DIV element with the class `dce-video-container`, make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative`, `absolute`, `fixed`, or `sticky`.
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  * Add the camera list and resolution list
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <select class="dce-sel-camera"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <select class="dce-sel-resolution"></select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ```html
-    <select class="dce-sel-resolution">
-        <option class="dce-opt-gotResolution" value="got"></option>
-        <option data-width="1920" data-height="1080">1920 x 1080</option>
-        <option data-width="1280" data-height="720">1280 x 720</option>
-        <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the library at
-[https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.0.0](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.0.0).
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`,  `Blob`,  `URL`/`createObjectURL`,  `Web Workers`
-
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=9.0.0&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-* `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page.
-  
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Advanced Usage
-
-In addition to the above basic settings, the library has many more settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=9.0.0&utm_source=guide).
-
-## How to Upgrade
-
-If you want to upgrade the library from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=9.0.0&utm_source=guide).
-
-## FAQ
-
-### Can I open the web page directly from the hard drive?
-
-Yes, for simple testing purposes, it's perfectly fine to open the file directly from the hard drive. However, you might encounter some issues in doing so (like unable to access the camera, etc.). The recommendation is to deploy this page to your web server and run it over **HTTPS**. If you don't have a ready-to-use web server but have a package manager like *npm* or *yarn*, you can set up a simple HTTP server in minutes. Check out [http-server on npm](https://www.npmjs.com/package/http-server).
-
-### Why can't I use my camera?
-
-If you open the web page as `file:///` or `http://` , the camera may not work and you see the following error in the browser console:
-
-> [Deprecation] getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See `https://goo.gl/rStTGz` for more details.
-
-In Safari 12 the equivalent error is:
-
-> Trying to call getUserMedia from an insecure document.
-
-You get this error because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: <a target="_blank" href="https://nginx.org/en/docs/http/configuring_https_servers.html" title="Configuring HTTPS servers">Configuring HTTPS servers</a>
-2. IIS: <a target="_blank" href="https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/" title="Create a Self Signed Certificate in IIS">Create a Self Signed Certificate in IIS</a>
-3. Tomcat: <a target="_blank" href="https://dzone.com/articles/setting-ssl-tomcat-5-minutes" title="Setting Up SSL on Tomcat in 5 minutes">Setting Up SSL on Tomcat in 5 minutes</a>
-4. Node.js: <a target="_blank" href="https://nodejs.org/docs/v0.4.1/api/tls.html" title="npm tls">npm tls</a>
-
-> If you use Chrome or Firefox, you might not get the error because these two browsers allow camera access via `file:///` and `http://localhost`. However, our recommendation is that you deploy the web page to a web server that supports HTTPS.
-
-### Accounting for newline characters in the barcode result
-
-When it comes to HTML, newline characters ( `\n` ) are not interpreted as they normally would. Therefore, if a barcode result contains a newline character, and you display the result in an modal dialogue box or some other text elements, then the newline character will probably be ignored.
-
-There are two ways in which you can resolve this:
-
-1. Wrap the element used to display the result in a `<pre>` element.
-2. Manually replace each `\n` character in the result with `<br>`

-
-#### About the code
-
-* `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-* `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-* `onFrameRead`: This event is triggered every time the library finishes scanning a video frame. The `results` object contains all the barcode results that the library have found on this frame. In this example, we print the results to the browser console.
-
-* `onUniqueRead`: This event is triggered when the library finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-* `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Step Two: Test the example
-
-To test the example, you can open the copy deployed to Dynamsoft Server <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.0.1&utm_source=guide" title="Run in Dynamsoft">here</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the library
-
-#### Use a CDN
-
-The simplest way to include the library is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.1/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.0.1/dist/dbr.js"></script>
-  ```
-
-#### Host the library yourself
-
-Besides using the CDN, you can also download the library and host its files on your own website / server before including it in your application.
-
-Options to download the library:
-
-* From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.0.1&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-* yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the library and where you put it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.0.1/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-Read more on [how to host the library](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=9.0.1&utm_source=guide&product=dbr&package=js#hosting-the-library).
-
-### Configure the library
-
-Before using the library, you need to configure a few things.
-
-#### Specify the license
-
-The library requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the library, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.0.1&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you registered a Dynamsoft account and downloaded the library from the official website, Dynamsoft will generate a 30-day trial license for you and put the license key into all the samples that come with the library.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the library where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.1/dist/";
-```
-
-### Interact with the library
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the library. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the library, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// Sets a scan interval in milliseconds so the library may release the CPU from time to time
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100;
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-> Find the full list of the runtime settings <a href="https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/global-interfaces.html?ver=9.0.1&utm_source=guide&&ver=latest#runtimesettings" target="_blank" title="here">here</a>.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=9.0.1&utm_source=guide).
-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.ui.html` directly.
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element into your own web page and specify it with the API `setUIElement(HTMLElement)`.
-
-  * Embed the video
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-ui-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  * Add the camera list and resolution list
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the library will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <div id="div-video-container">
-        <select class="dce-sel-camera"></select>
-        <select class="dce-sel-resolution"></select>
-        <br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ```html
-    <select class="dce-sel-resolution">
-        <option class="dce-opt-gotResolution" value="got"></option>
-        <option data-width="1920" data-height="1080">1920 x 1080</option>
-        <option data-width="1280" data-height="720">1280 x 720</option>
-        <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the library will then use it to show the actual resolution.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the library at
-[https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.0.1](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.0.1).
-
-## System Requirements
-
-This library requires the following features which are supported by all modern mainstream browsers:
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the library to work.
-
-* `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=9.0.1&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-* `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the library files on the same domain as your web page.
-  
-  <sup>3</sup> Safari 11.2.2 ~ 11.2.6 are not supported.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the library. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## Advanced Usage
-
-In addition to the above basic settings, the library has many more settings and options that you can adjust to best suit your usage. To read more, please see [advanced usage](https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/advanced-usage.html?ver=9.0.1&utm_source=guide).
-
-## How to Upgrade
-
-If you want to upgrade the library from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=9.0.1&utm_source=guide).

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-* Basic Requirements
-  * Internet connection
-  * [A supported browser](#system-requirements)
-  * Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below

-#### About the code
-
-* `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-* `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-* `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-* `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-* `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.0.2&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-* jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.2/dist/dbr.js"></script>
-  ```
-
-* UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.0.2/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the CDN, you can also download the SDK and host its files on your own website / server before including it in your application.
-
-Options to download the SDK:
-
-* From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.0.2&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-* yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-* npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.0.2/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.0.2&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you registered a Dynamsoft account and downloaded the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you and put the license key into all the samples that come with the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.0.2/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds)
-scanSettings.duplicateForgetTime = 5000;
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100;
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance" and "coverage"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-* Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-* `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-* `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-* Modify the file `dist/dbr.ui.html` directly.
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-* Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-  
-  > You must set `defaultUIElementURL` before you call `createInstance()` .
-
-* Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-* Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`.
-
-  * Embed the video
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-ui-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  * Add the camera list and resolution list
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <div id="div-ui-container">
-        <select class="dce-sel-camera"></select>
-        <select class="dce-sel-resolution"></select>
-        <br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, 8 hard-coded resolutions are populated as options. You can show only a custom set of options by hardcoding them.
-
-    ```html
-    <select class="dce-sel-resolution">
-        <option class="dce-opt-gotResolution" value="got"></option>
-        <option data-width="1920" data-height="1080">1920 x 1080</option>
-        <option data-width="1280" data-height="720">1280 x 720</option>
-        <option data-width="640" data-height="480">640 x 480</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the nearest supported resolution. As a result, the selected resolution may not be the actual resolution used. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will then use it to show the actual resolution.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.0.2](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.0.2).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-* Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  * Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  * Dynamsoft License requires a secure context to work.
-
-* `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-* `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=9.0.2&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-* `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=9.0.2&utm_source=guide).
-
-## Next Steps

-#### About the code
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.2.12&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.2.12/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.2.12/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the CDN, you can also download the SDK and host its files on your own website / server before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.2.12&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.2.12/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.2.12&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you registered a Dynamsoft account and downloaded the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you and put the license key into all the samples that come with the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.2.12/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/programming/javascript/samples-demos/parameter-settings.html?ver=9.2.12&utm_source=guide).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-- Modify the file `dist/dbr.ui.html` directly.
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-- Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  // This line only takes effect when it is put before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-- Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-- Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-ui-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <div id="div-ui-container">
-        <select class="dce-sel-camera"></select>

-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will then use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.2.12](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.2.12).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=9.2.12&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=9.2.12&utm_source=guide).

-#### About the code
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.2.13&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: <a target="_blank" href="https://nginx.org/en/docs/http/configuring_https_servers.html" title="Configuring HTTPS servers">Configuring HTTPS servers</a>

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.2.13/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.2.13/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the CDN, you can also download the SDK and host its files on your own website / server before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.2.13&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.2.13/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.2.13&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you registered a Dynamsoft account and downloaded the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you and put the license key into all the samples that come with the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.2.13/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-- Modify the file `dist/dbr.ui.html` directly.
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-- Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  // This line only takes effect when it is put before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-- Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-- Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-ui-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <div id="div-ui-container">
-        <select class="dce-sel-camera"></select>
-        <select class="dce-sel-resolution"></select>
-        <br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, only 3 hard-coded resolutions (3840 x 2160, 1920 x 1080, 1280 x 720), are populated as options. You can show a customized set of options by hardcoding them.
-
-    ```html
-    <select class="dce-sel-resolution">
-        <option class="dce-opt-gotResolution" value="got"></option>
-        <option data-width="1280" data-height="720">1280x720</option>
-        <option data-width="1920" data-height="1080">1920x1080</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will then use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.2.13](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.2.13).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=9.2.13&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=9.2.13&utm_source=guide).

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use (https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.3.1/dist/dbr.js)[https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.3.1/dist/dbr.js] for the test. However, please remember this link is temporary and DO NOT use it in your production application. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.3.1&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: <a target="_blank" href="https://nginx.org/en/docs/http/configuring_https_servers.html" title="Configuring HTTPS servers">Configuring HTTPS servers</a>

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.3.1/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.3.1/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.3.1&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.3.1/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time to maximize the performance of your web application.
-
-```cmd
-Cache-Control: max-age=31536000
-```
-
-Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.3.1&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you registered a Dynamsoft account and downloaded the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you and put the license key into all the samples that come with the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.3.1/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-- Modify the file `dist/dbr.ui.html` directly.
-
-  This option is only possible when you host this file on your own web server instead of using a CDN.
-
-- Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI.
-
-  ```javascript
-  // This line only takes effect when it is put before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-- Append the default UI element to your page, customize it before showing it.
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-- Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`.
-
-  - Embed the video
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    <script>
-        (async () => {
-            let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-            await scanner.setUIElement(document.getElementById('div-ui-container'));
-            scanner.onFrameRead = results => {
-                console.log(results);
-            };
-            scanner.onUniqueRead = (txt, result) => {
-                alert(txt);
-            };
-            await scanner.show();
-        })();
-    </script>
-    ```
-
-    > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-  - Add the camera list and resolution list
-
-    If the class names for these lists match the default ones, `dce-sel-camera` and `dce-sel-resolution` , the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-    ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-    ```html
-    <div id="div-ui-container">
-        <select class="dce-sel-camera"></select>
-        <select class="dce-sel-resolution"></select>
-        <br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-    > By default, only 3 hard-coded resolutions (3840 x 2160, 1920 x 1080, 1280 x 720), are populated as options. You can show a customized set of options by hardcoding them.
-
-    ```html
-    <select class="dce-sel-resolution">
-        <option class="dce-opt-gotResolution" value="got"></option>
-        <option data-width="1280" data-height="720">1280x720</option>
-        <option data-width="1920" data-height="1080">1920x1080</option>
-    </select>
-    ```
-
-    [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-    > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will then use it to show the **actual resolution**.

-
-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.3.1](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/?ver=9.3.1).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/programming/javascript/api-reference/BarcodeScanner.html?ver=9.3.1&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/programming/javascript/upgrade-guide/?ver=9.3.1&utm_source=guide).

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.1/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.1/dist/dbr.js) for the test. However, please DO NOT use it in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.1&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.1/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.1/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.1&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.1/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.1&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.1/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API setUIElement(HTMLElement)
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.1](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.1).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.1&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.1&utm_source=guide).

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-- Basic Requirements
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below
-
-```html

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.10/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.10/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.10&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.10/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.10/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.10&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.10/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.10&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.10/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.10](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.10).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.10&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.11/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.11/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.11&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.11/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.11/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.11&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.11/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.11&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.11/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.11](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.11).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.11&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.11&utm_source=guide).

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-- Basic Requirements
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below
-
-```html

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.2/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.2/dist/dbr.js) for the test. However, please DO NOT use it in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.2&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.2/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.2/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.2&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn

-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.2/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.2&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.2/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API setUIElement(HTMLElement)
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.2](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.2).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.2&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.2&utm_source=guide).

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.20/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.20/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.20&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.20/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.20/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.20&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.20/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.20&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.20/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the cloest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.20](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.20).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.20&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.20&utm_source=guide).

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-- Basic Requirements
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below
-
-```html
-<!DOCTYPE html>

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.21/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.21/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.21&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.21/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.21/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.21&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.21/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.21&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.21/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.21](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.21).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.21&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.21&utm_source=guide).

-
-- Basic Requirements
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.30/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.30/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.30&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.30/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.30/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.30&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.30/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.30&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.30/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.30](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.30).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.30&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.30&utm_source=guide).

-
-- Basic Requirements
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.31/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.31/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.31&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.31/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.31/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-

-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.31/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.31&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.31/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.31](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.31).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.31&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.31&utm_source=guide).

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.32/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.32/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.32&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.32/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.32/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.32&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.32/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.32&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.32/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.32](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.32).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.32&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.32&utm_source=guide).

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-- Basic Requirements
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below
-
-```html
-<!DOCTYPE html>

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.33/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.33/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.33&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.33/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.33/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.33&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.33/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.33&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.33/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.33](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.33).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.33&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.33&utm_source=guide).

-
-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.40/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.40/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.40&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.40/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.40/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.40&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode
-  ```
-
-- npm
-
-  ```cmd
-  npm install dynamsoft-javascript-barcode --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.40/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.40&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.40/dist/";
-```
-
-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).
-
-  See also [settings samples](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/samples-demos/parameter-settings.html?ver=9.6.40&utm_source=guide).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.40](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.40).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.40&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/?ver=9.6.40&utm_source=guide).

-#### About the code
-
-- The DBR-JS SDK is included in the code via the **jsDelivr** CDN.
-
-> In some rare cases, you might not be able to access the CDN. If this happens, you can use [https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.42/dist/dbr.js](https://download2.dynamsoft.com/dbr/dynamsoft-barcode-reader-js/dynamsoft-barcode-reader-js-9.6.42/dist/dbr.js) for the test. However, please DO NOT use CDN of `download2.dynamsoft.com` in your production application because it is temporary. Instead, you can try [hosting the SDK yourself](#host-the-sdk-yourself).
-
-- `license`: This property specifies a license key. Note that the license "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" used in this example is an online license and requires network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `createInstance()`: This method creates a `BarcodeScanner` object. This object can read barcodes directly from a video input with the help of its interactive UI (hidden by default) and the <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices" title="MediaDevices interface">MediaDevices interface</a>.
-
-- `onFrameRead`: This event is triggered every time the SDK finishes scanning a video frame. The `results` object contains all the barcode results that the SDK have found on this frame. In this example, we print the results to the browser console.
-
-- `onUniqueRead`: This event is triggered when the SDK finds a new barcode, which is not a duplicate among multiple frames. `txt` holds the barcode text value while `result` is an object that holds details of the barcode. In this example, an alert will be displayed for this new barcode.
-
-- `show()`: This method brings up the built-in UI of the `BarcodeScanner` object and starts scanning.
-
-### Run the example
-
-You can run the example deployed to <a target="_blank" href="https://demo.dynamsoft.com/Samples/DBR/JS/1.hello-world/1.hello-world.html?ver=9.6.42&utm_source=guide" title="Run in Dynamsoft">the Dynamsoft Demo Server</a> or test it with <a target="_blank" href="https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/" title="Run in JSFiddle">JSFiddle code editor</a>. You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text pop up and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can make a local test simply by taking the code in step 1, pasting it in a file with the name "hello-world.html" and open it in a browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the API <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia" title="getUserMedia">getUserMedia</a> usually requires HTTPS to access the camera.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: <a target="_blank" href="https://nginx.org/en/docs/http/configuring_https_servers.html" title="Configuring HTTPS servers">Configuring HTTPS servers</a>

-
-## Building your own page
-
-### Include the SDK
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js"></script>
-  ```
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  <a target="_blank" href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=9.6.42&utm_source=guide" title="Download the JavaScript Package">Download the JavaScript Package</a>
-
-- npm
-
-  ```cmd
-  npm i dynamsoft-javascript-barcode -E
-  ```
-
-- yarn
-
-  ```cmd
-  yarn add dynamsoft-javascript-barcode -E
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="/dynamsoft-barcode-reader-js-9.6.42/dist/dbr.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-javascript-barcode/dist/dbr.js"></script>
-```
-
-or
-
-```typescript
-import { BarcodeScanner } from 'dynamsoft-javascript-barcode';
-```
-
-**NOTE**
-
-* Some older web application servers do not set `.wasm` mimetype as `application/wasm`. Upgrade your web application servers, or define the mimetype yourselves:
-  * [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-  * [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-  * [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Configure the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-The SDK requires a license to work, use the API `license` to specify a license key.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-```
-
-To test the SDK, you can request a 30-day trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=9.6.42&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> If you register a Dynamsoft account and download the SDK from the official website, Dynamsoft will automatically generate a 30-day trial license for you, and put the license key into all the samples attached to the SDK.
-
-#### Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular or React, etc. where dbr.js is compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `engineResourcePath`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.DBR.BarcodeScanner.engineResourcePath = "https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/";
-```

-### Interact with the SDK
-
-#### Create a `BarcodeScanner` object
-
-You can use one of two classes ( `BarcodeScanner` and `BarcodeReader` ) to interact with the SDK. `BarcodeReader` is a low-level class that processes images directly. `BarcodeScanner` , on the other hand, inherits from `BarcodeReader` and provides high-level APIs and a built-in GUI to allow continuous barcode scanning on video frames. We'll focus on `BarcodeScanner` in this guide.
-
-To use the SDK, we first create a `BarcodeScanner` object.
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let scanner = null;
-try {
-    scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-Tip: When creating a `BarcodeScanner` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pScanner` in the following code
-
-```javascript
-Dynamsoft.DBR.BarcodeScanner.license = "YOUR-LICENSE-KEY";
-let pScanner = null;
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        const scanner = await (pScanner = pScanner || Dynamsoft.DBR.BarcodeScanner.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Customize the `BarcodeScanner` Settings (optional)
-
-Let's take a look at the following code snippets:
-
-```javascript
-// Sets which camera and what resolution to use
-let allCameras = await scanner.getAllCameras();
-await scanner.setCurrentCamera(allCameras[0].deviceId);
-await scanner.setResolution(1280, 720);
-```
-
-```javascript
-// Sets up the scanner behavior
-let scanSettings = await scanner.getScanSettings();
-// Disregards duplicated results found in a specified time period (in milliseconds).
-scanSettings.duplicateForgetTime = 5000; // The default is 3000
-// Sets a scan interval in milliseconds so the SDK may release the CPU from time to time.
-// (setting this value larger is a simple way to save battery power and reduce device heating).
-scanSettings.intervalTime = 100; // The default is 0.
-// Sets captureAndDecodeInParallel to false, which tells the SDK not to acquire the next frame while decoding the first.
-// This is another way to save battery power and is recommended on low-end phones. However, it does slow down the decoding speed.
-scanSettings.captureAndDecodeInParallel = false; // The default is true.
-await scanner.updateScanSettings(scanSettings);
-```
-
-```javascript
-// Uses one of the built-in RuntimeSetting templates: "single" (decode a single barcode, the default mode), "speed", "balance", "coverage", "dense" and "distance"
-await scanner.updateRuntimeSettings("speed");
-
-// Makes changes to the template. The code below demonstrates how to specify enabled symbologies
-let runtimeSettings = await scanner.getRuntimeSettings();
-runtimeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED | Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await scanner.updateRuntimeSettings(runtimeSettings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/yfkcajxz/)
-
-As you can see from the above code snippets, there are three types of configurations:
-
-- Customize the data source: This configuration includes which camera to use, the preferred resolution, etc. Learn more <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia#Syntax" target="_blank" title="here">here</a>.
-
-- `get/updateScanSettings`: Configures the behavior of the scanner which includes `duplicateForgetTime` and `intervalTime`, etc.
-
-- `get/updateRuntimeSettings`: Configures the decode engine with either a built-in template or a comprehensive `RuntimeSettings` object. For example, the following uses the built-in "speed" settings with updated `localizationModes`.
-
-  ```javascript
-  await barcodeScanner.updateRuntimeSettings("speed");
-  //await barcodeScanner.updateRuntimeSettings("balance"); //alternative
-  //await barcodeScanner.updateRuntimeSettings("coverage"); //alternative
-  let settings = await barcodeScanner.getRuntimeSettings();
-  settings.localizationModes = [
-      Dynamsoft.DBR.EnumLocalizationMode.LM_CONNECTED_BLOCKS,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_SCAN_DIRECTLY,
-      Dynamsoft.DBR.EnumLocalizationMode.LM_LINES, 0, 0, 0, 0, 0
-  ];
-  await barcodeScanner.updateRuntimeSettings(settings);
-  ```
-
-  Try in [JSFiddle](https://jsfiddle.net/DynamsoftTeam/f24h8c1m/).

-
-### Customize the UI (optional)
-
-The built-in UI of the `BarcodeScanner` object is defined in the file `dist/dbr.ui.html` . There are a few ways to customize it:
-
-#### Modify the file `dist/dbr.ui.html` directly
-
-  This option is only possible when you [Host the SDK yourself](#host-the-sdk-yourself) instead of using a public CDN.
-
-#### Copy the file `dist/dbr.ui.html` to your application, modify it and use the the API `defaultUIElementURL` to set it as the default UI
-
-  ```javascript
-  // This line only takes effect before the method `createInstance()` is called.
-  Dynamsoft.DBR.BarcodeScanner.defaultUIElementURL = "THE-URL-TO-THE-FILE";
-  ```
-
-#### Append the default UI element to your page, customize it before showing it
-
-  ```html
-  <div id="div-ui-container"></div>
-  ```
-
-  ```javascript
-  document.getElementById('div-ui-container').appendChild(scanner.getUIElement());
-  document.getElementsByClassName('dce-btn-close')[0].hidden = true; // Hide the close button
-  ```
-
-#### Build the UI element from scratch and connect it to the SDK with the API `setUIElement(HTMLElement)`
-
-1. **Embed the video**
-  
-  ```html
-  <div id="div-ui-container" style="width:100%;height:100%;">
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  <script>
-      (async () => {
-          let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-          await scanner.setUIElement(document.getElementById('div-ui-container'));
-          scanner.onFrameRead = results => {
-              console.log(results);
-          };
-          scanner.onUniqueRead = (txt, result) => {
-              alert(txt);
-          };
-          await scanner.show();
-      })();
-  </script>
-  ```
-
-  > The video element will be created and appended to the DIV element with the class `dce-video-container` , make sure the class name is the same. Besides, the CSS property `position` of the DIV element must be either `relative` , `absolute` , `fixed` , or `sticky` .
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/2jzeq1r6/)
-
-2. **[Optional] Add the camera list and resolution list**
-
-  If the class names of the created select elements match the default class names, i.e. `dce-sel-camera` and `dce-sel-resolution` respectively, the SDK will automatically populate the lists and handle the camera/resolution switching.
-
-  ```html
-    <div id="div-ui-container" style="width:100%;height:100%;">
-        <select class="dce-sel-camera"></select><br>
-        <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-    </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/nbj75vxu/)
-
-  ```html
-  <div id="div-ui-container">
-      <select class="dce-sel-camera"></select>
-      <select class="dce-sel-resolution"></select>
-      <br>
-      <div class="dce-video-container" style="position:relative;width:100%;height:500px;"></div>
-  </div>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/25v08paf/)
-
-  > By default, only 3 hard-coded resolutions (1920 x 1080, 1280 x 720，640 x 480) are populated as options. You can show a customized set of options by hardcoding them.
-
-  ```html
-  <select class="dce-sel-resolution">
-      <option class="dce-opt-gotResolution" value="got"></option>
-      <option data-width="1280" data-height="720">1280x720</option>
-      <option data-width="1920" data-height="1080">1920x1080</option>
-  </select>
-  ```
-
-  [Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/tnfjks4q/)
-
-  > Generally, you need to provide a resolution that the camera supports. However, in case a camera does not support the specified resolution, it usually uses the closest supported resolution. As a result, the selected resolution may not be the actual resolution. In this case, add an option with the class name `dce-opt-gotResolution` (as shown above) and the SDK will automatically use it to show the **actual resolution**.

-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.42](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=9.6.42).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is only required for in-browser video streaming. If a browser does not support this API, the [Single Frame Mode](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/BarcodeScanner.html?ver=9.6.42&utm_source=guide#singleframemode) will be used automatically. If the API exists but doesn't work correctly, the Single Frame Mode can be used as an alternative way to access the camera.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  Browser Name | Version
-  :-: | :-:
-  Chrome | v59+<sup>1</sup>
-  Firefox | v52+ (v55+ on Android/iOS<sup>1</sup>)
-  Edge<sup>2</sup> | v16+
-  Safari<sup>3</sup> | v11+
-
-  <sup>1</sup> iOS 14.3+ is required for camera video streaming in Chrome and Firefox or Apps using webviews.
-
-  <sup>2</sup> On Edge, due to strict Same-origin policy, you must host the SDK files on the same domain as your web page.
-  
-  <sup>3</sup> Safari v11.x already has the required features, but it has many other issues, so we recommend v12+.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-

-# Advanced Usage
-
-- [Advanced Usage](#advanced-usage)
-  - [Read a specific area/region](#read-a-specific-arearegion)
-  - [Account for newline characters in the barcode result](#account-for-newline-characters-in-the-barcode-result)

-  - [Display images in different stages of the reading process](#display-images-in-different-stages-of-the-reading-process)
-
-## Read a specific area/region
-
-To speed up the scanning process, you can choose to scan only a specific area/region.
-
-```javascript
-let settings = await scanner.getRuntimeSettings();
-/*
- * The following code shrinks the decoding region by 25% on all sides
- */
-settings.region.regionMeasuredByPercentage = 1;
-settings.region.regionLeft = 25;
-settings.region.regionTop = 25;
-settings.region.regionRight = 75;
-settings.region.regionBottom = 75;
-await scanner.updateRuntimeSettings(settings);
-```
-
-[Try in JSFiddle](https://jsfiddle.net/DynamsoftTeam/taykq592/)
-
-## Account for newline characters in the barcode result
-
-When it comes to HTML, newline characters ( `\n` ) are not interpreted as they normally would. Therefore, if a barcode result contains a newline character, and you display the result in an modal dialogue box or some other text elements, then the newline character will probably be ignored.
-
-There are two ways in which you can resolve this:
-
-1. Wrap the element used to display the result in a `<pre>` element.
-2. Manually replace each `\n` character in the result with `<br>`
-
-## Show internal logs
-
-Include the following in your code to print internal logs in the console.
-
-```javascript
-Dynamsoft.DBR.BarcodeReader._onLog = console.log;
-```
-
-## Set mode arguments
-
-To precisely control a mode, you can adjust its specific parameters.
-
-```javascript
-let settings = await scanner.getRuntimeSettings();
-
-/*
- * The following code sets the sensitivity of the TextureDetectionModes to 9
- */
-
-settings.furtherModes.textureDetectionModes = [
-    Dynamsoft.DBR.EnumTextureDetectionMode.TDM_GENERAL_WIDTH_CONCENTRATION, 0, 0, 0, 0, 0, 0, 0
-];
-
-await scanner.updateRuntimeSettings(settings);
-// The 2nd parameter 0 specifies the 0th mode of TextureDetectionModes, 
-// which is "Dynamsoft.DBR.EnumTextureDetectionMode.TDM_GENERAL_WIDTH_CONCENTRATION" in this case.
-await scanner.setModeArgument("TextureDetectionModes", 0, "Sensitivity", "9");
-```
-
-## Display images in different stages of the reading process
-
-The original canvases are saved when setting `ifSaveOriginalImageInACanvas` to `true`. The method `getOriginalImageInACanvas()` returns a canvas which holds the image to be passed to the barcode reader engine for decoding. 
-
-The intermediate result canvases are created when `intermediateResultTypes` is set to a value other than `IRT_NO_RESULT` . Then these intermediate result canvases can be returned with the method `getIntermediateCanvas()` to be used for showing and debugging the barcode reading process. 
-
-> *NOTE*
->  
-> For efficiency, the library may utilize WebGL (Web Graphics Library) for preprocessing an image before passing it to the barcode reader engine. If WebGL is used, the image captured from the camera will not be rendered on the canvas, instead, it gets processed by WebGL first and then is passed to the barcode reader engine directly. In this case, there won't be an original canvas.
-> 
-> Therefore, if `ifSaveOriginalImageInACanvas` is set to `true` for a `BarcodeScanenr` instance, the WebGL feature will be disabled for that instance.
->
-> You can manually disable the WebGL feature by setting `_bUseWebgl` as `false`. If WebGL is disabled, when you try to get the intermediate result canvas (with `getIntermediateCanvas()`) specified by `EnumIntermediateResultType.IRT_ORIGINAL_IMAGE` , the canvas will be exactly the same image as you would get with `getOriginalImageInACanvas()` .
-
-The following shows how to display these images on the page
-
-```html
-<div id='scannerV' style="width:50vw;height:50vh"></div>
-<div id='cvses'></div>
-```
-
-```javascript
-// original canvas
-(async () => {
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    document.getElementById('scannerV').appendChild(scanner.getUIElement());
-    scanner.ifSaveOriginalImageInACanvas = true;
-    scanner.onUniqueRead = async (txt, result) => {
-        try {
-            let cvs = scanner.getOriginalImageInACanvas();
-            document.getElementById('cvses').appendChild(cvs);
-            scanner.destroyContext();
-        } catch (ex) {
-            console.error(ex);
-        }
-    };
-    await scanner.show();
-})();
-```
-
-```javascript
-// intermediate result canvas
-(async () => {
-    let scanner = await Dynamsoft.DBR.BarcodeScanner.createInstance();
-    // scanner._bUseWebgl = false;
-    document.getElementById('scannerV').appendChild(scanner.getUIElement());
-    let rs = await scanner.getRuntimeSettings();
-    rs.intermediateResultTypes = Dynamsoft.DBR.EnumIntermediateResultType.IRT_ORIGINAL_IMAGE;
-    await scanner.updateRuntimeSettings(rs);
-    scanner.onUniqueRead = async (txt, result) => {
-        try {
-            let cvss = await scanner.getIntermediateCanvas();
-            for (let cvs of cvss) {
-                document.getElementById('cvses').appendChild(cvs);
-            }
-            scanner.destroyContext();
-        } catch (ex) {
-            console.error(ex);
-        }

----
-
-# How to Upgrade
-
-## From v8.x to v8.2.5
-
-In v8.2.5, we introduced the API `organizationID` as the recommended way to fetch a trackable license. However, all old ways of licensing the library are still supported.
-
----
-## From v8.x to v8.1.2
-
-### `TextResult` exception
-
-In v8.1, we added exceptions to the `TextResult` class. An exception message and code is returned with each result if no valid license (trial or full) is present.
-
-The following is an example of what may be returned:
-
-`[Attention(exceptionCode:-20000)] http:/*d*n*m*soft.q*.com*r/U4***U*EaRA****W9*ZB`
-
-More details on the exception can be found within each result. For example:
-
-```
-result.exception = {
-   code: "-20000",
-   message: "No license specified. Visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=guide&product=dbr&package=js to acquire a license or email support@dynamsoft.com."
-}
-```
-
----
-## From v7.x to v8.x
-
-### Change your license
-
-In v8.0, we introduced a new license tracking mechanism, [License 2.0](https://www.dynamsoft.com/license-tracking/docs/about/index.html). If you have a v7.x license and wish to upgrade to v8.x, you must [contact us](https://www.dynamsoft.com/Company/Contact.aspx) to acquire a new license. 
-
-### Update version and code
-
-If you are using a **CDN**, simply update the version number denoted after **@** in the URL.
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@8.8.7/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-```
-
-If you have deployed the library files to your server, you'll need to replace the old files with the ones in the latest version. Download the latest version [here](https://www.dynamsoft.com/Downloads/Dynamic-Barcode-Reader-Download.aspx).
-
-Next, replace the value ("PRODUCT-KEYS") of `data-productKeys` with the handshake code or organization ID you receive based on License 2.0 (as mentioned in the section [Change your license](#change-your-license) above).
-
-### API changes
-
-#### :exclamation: *Namespace change*
-
-Use the new namespace `Dynamsoft.DBR` in place of just `Dynamsoft`. The following shows the equivalent changes for `BarcodeScanner` and `BarcodeReader`:
-
-```js
-Dynamsoft.BarcodeScanner -> Dynamsoft.DBR.BarcodeScanner
-Dynamsoft.BarcodeReader -> Dynamsoft.DBR.BarcodeReader
-```
-
-If you are using the library as an ES/CMD module, you don't need to change your code. Otherwise, you can either make a global change from `Dynamsoft` to `Dynamsoft.DBR` or use the following line to quickly make the namespace change.
-
-```js
-Dynamsoft = Dynamsoft.DBR; //This line should be called before you call any other methods/properties of the library.
-```
-
-#### Deprecating `deblurLevel`
-
-`deblurLevel` has been deprecated in v8.0 and replaced with `deblurModes`. Although `deblurLevel` will continue to work in v8.0, we recommend updating your code to use `deblurModes` as soon as possible to avoid any breaking changes in the future.
-
-Check out the code below on how to switch from `deblurLevel` to `deblurModes`.
-
-```js
-let settings = await barcodeScanner.getRuntimeSettings();
-//settings.deblurLevel = 9;

-
-#### Default runtime setting has changed from `speed` to `single` for `BarcodeScanner`
-
-The `single` runtime setting was introduced in v7.5 as an experimental feature for `BarcodeScanner`. In v8.0, `single` is made the default setting.
-
-Before v8.0, the default setting was `speed`.
-
-*NOTE*
-
-`BarcodeReader` still uses `coverage` as the default setting.
-
-#### Removed some deprecated APIs from `textResult`
-
-* `BarcodeText` is removed, use `barcodeText` instead
-* `BarcodeFormat` is removed, use `barcodeFormat` instead
-* `BarcodeFormatString` is removed, use `barcodeFormatString` instead
-* `LocalizationResult` is removed, use `localizationResult` instead
-* `ResultPoints` in `localizationResult` is removed, use `x1,x2,x3,x4,y1,y2,y3,y4` instead
-* `accompanyingTextBytes` is removed, if you wish to use the feature or something similar, please [contact us](https://www.dynamsoft.com/Company/Contact.aspx).

-| `barcodeResults` (optional)      | [`Array<BarcodeResultItem>`]({{ site.js_api }}interfaces/barcode-result-item.html)  | An array of BarcodeResultItem Represents the decoded barcode(s).         |
-
-**Code Snippet**
-
-```js
-(async () => {
-    // Launch the scanner and wait for the result
-    const result = await barcodeScanner.launch();
-    console.log(result.status.message); // prints the result status message to the console
-    console.log(result.status.code); // prints the result status code to the console
-    console.log(result.barcodeResults); // prints an array containing all the decoded barcode results to the console. Note that in SM_SINGLE mode, the length of this array is 1.
-})();
-```
-
-### UtilizedTemplateNames
-
-An object that defines the names of templates utilized by the BarcodeScanner for different scanning modes.
-
-```ts
-interface UtilizedTemplateNames {
-  single: string;
-  multi_unique: string;

-# Introduction to Dynamsoft Barcode Reader JavaScript Edition version 10.x
-
-Dynamsoft Barcode Reader (DBR) can be used in JavaScript to add barcode reading capabilities to websites running in modern browsers. It is ideal for
-
-* organizations who already have sophisticated websites and do not intend to develop mobile applications for the same purposes; or
-* organizations whose customers have no desire to install applications for temporary usage of their services.
-
-To get a fast start, you can
-
-* read the [User Guide](user-guide/), or
-* try the [Samples and Demos](samples-demos/)
-
-The following describes the highlights of DBR JavaScript edition (DBR-JS) version 10.x.
-
-## Fast Integration
-
-This [JSFiddle example](https://jsfiddle.net/DynamsoftTeam/csm2f9wb/) demonstrates all the code needed to build a web application using DBR, end users of the web page can open it in a browser, access their cameras and read barcodes directly from the video input.
-
-### Camera Control
-
-Customers generally need to scan a barcode on the fly at which time there is no better input than the camera hooked to or built into the device itself. As shown in the code snippet above, the product **Dynamsoft Camera Enhancer (DCE)** is used to provide camera support. It makes use of the powerful [**MediaDevices**](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices) interface (provided by the browser itself) to instantly access the video input of the camera, capture image frames and supply them to the back-end decoding engine.
-
-> DBR and DCE communicate through the interface called [Image Source Adapter]({{ site.dcvb_architecture }}input.html#image-source-adapter?lang=js).
-
-### Interactive UI
-
-Good interaction design is essential for a website. With the help of DCE, the barcode reading process is made interactive as shown in the screenshot below.
-
-![Interactive UI](assets/interactive-ui.png)
-
-## High Performance
-
-Barcode reading is usually just an auxiliary way to assist a small step in a complex workflow. Customers like the convenience, but if it takes too long or is error-prone, their patience will quickly run out. Therefore, high performance is crucial.
-
-### Unparalleled Speed
-
-DBR showcases Dynamsoft's cutting-edge technology in light-speed recognition of barcodes. In most cases, an image gets deblurred, binarized and read under 100 milliseconds.
-
-With the help of DCE JS, DBR no longer wastes time on image capture and often gets high-quality images for processing, which further increases its speed.
-
-### Proficiency in Handling Difficult Environments
-
-The actual use environment is unpredictable. The barcode may appear distorted, inverted, or partially damaged; the background may be textured or spotted; the light may be very low, and there may be shadows and glare. DBR handles all these cases with its rich image processing algorithms through various adjustable settings.
-
-### Exceptional Accuracy
-
-DBR does a lot of preparation work to make sure the barcode is as legible as possible for the decoding engine to read. This ensures a very high accuracy. In addition, DBR achieves even higher accuracy through the following ways:
-
-* DBR can verify results by comparing the results of multiple consecutive recognitions;
-* DBR has a confidence score for each recognition which can be used to filter unwanted results;
-* DBR is also able to verify the barcode result with printed text that accompanies the barcode with the help of the product **Dynamsoft Label Recognizer (DLR)**.
-
-Through many experiences, DBR has also cultivated its error correction ability to handle
-
-* Non-standard barcodes which do not strictly abide by the specification;
-* Deformed barcodes which are usually caused by improper printing.
-
-## Effortless Expansion
-
-DBR-JS v10.x is based on [Dynamsoft Capture Vision]({{site.dcvb_architecture}}) which is a modular architecture. This architecture makes it easy to add new functionality or custom behavior with very little change to the code. Two examples are:
-
-* Add **Dynamsoft Document Normalizer (DDN)** to do perspective correction before pass an image frame to read barcodes;
-* Add **Dynamsoft Code Parser (DCP)** to parse the text embedded in the PDF417 on driver's licenses.
-
-## Next Step
-
-Read the [User Guide](user-guide/) to start building your own websites with barcode reading capabilities.

-# ✨New in v10.5.3000: BarcodeScanner – Simplified API and Built-in UI
-
-Version 10.5.3000 introduces the all-new `BarcodeScanner` class, offering a streamlined API and a prebuilt interactive UI, making barcode scanning integration easier than ever. This is now the recommended way to use DBR-JS, especially for developers who want a quick, clean, and robust scanning experience with minimal setup.
-
-With `BarcodeScanner`, you can:
-
-- Instantiate and configure the scanner with just a few lines of code;
-
-- Select your scanning mode and present a ready-to-use scanning interface;
-
-- Focus on your application logic without worrying about camera setup, UI rendering, or lifecycle management.
-
-> [!TIP]
-> You can either get a [quick start with the BarcodeScanner APIs](user-guide/barcode-scanner.html) or experience a highly customizable [development with the foundational APIs](user-guide/index.html). If you're just starting out, we highly recommend using the `BarcodeScanner` class for the best balance of simplicity, performance, and user experience.

-# How to Upgrade DBR-JS from v10.x to v11.x
-
-## Reference the latest version of the dynamsoft-barcode-reader-bundle
-
-To use version 11, include the following script in your HTML:
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-```
-
-## APIs changes introduced in v11
-
-### BarcodeScanner API Changes
-
-Several properties have been renamed or had their default values changed. Please review the table below and update your implementation accordingly if you rely on the previous defaults.
-
-| Property                                | Old Default | New Default | Notes                                                          |
-| --------------------------------------- | ----------- | ----------- | -------------------------------------------------------------- |
-| `removePoweredByMessage` *(deprecated)* | `false`     | —           | Replaced by `showPoweredByDynamsoft`                           |
-| `showPoweredByDynamsoft`                | `false`     | `true`      | Controls whether the "Powered by Dynamsoft" label is displayed |
-| `showCloseButton`                       | `false`     | `true`      | Controls whether the close button is shown in the scannerView  |
-| `showResultView`                        | `false`     | `true`      | Controls whether the result view is shown                      |
-
-> [!NOTE]
-> If your project depends on the previous default behavior, you must explicitly set these properties to maintain compatibility.
-
-### Foundational API Changes
-
-#### loadWasm() Simplified
-
-The loadWasm() function no longer requires any parameters. Simply call loadWasm() without arguments.
-
-```javascript
-Dynamsoft.Core.CoreModule.loadWasm();
-```
-
-#### engineResourcePaths Simplified
-
-There is no longer a need to define `engineResourcePaths` for different modules. Resource management has been centralized and streamlined.
-
-```javascript
-// To specify the path for rootDirectory
-Dynamsoft.Core.CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-
-> [!NOTE]
-> Remove unnecessary parameters from `loadWasm()` calls.
-> 
-> Eliminate any redundant configuration of `engineResourcePaths`.
-
-### Upgrade your template
-
-The template system is upgraded. The template you used for the previous version can’t be directly recognized by the new version. Please use the [template upgrade tool](https://www.dynamsoft.com/tools/template-upgrade/) to upgrade your template.
-
-## From version 9.x or earlier
-
-The Dynamsoft Barcode Reader JavaScript edition has been refactored to integrate with DynamsoftCaptureVision (DCV) architecture since version 10. To understand the advantages of this new architecture, please refer to these resources:
-
-* [Overview of Dynamsoft Capture Vision](https://www.dynamsoft.com/capture-vision/docs/core/introduction/)
-* [Dynamsoft Capture Vision Framework Details](https://www.dynamsoft.com/capture-vision/docs/core/architecture/)
-
-> [!IMPORTANT]
-> 
-> Dynamsoft’s ongoing feature development is based on the new DCV architecture. By upgrading to v11, you’ll gain access to improved performance and new capabilities.
-
-Due to the architectural changes, **a significant rewrite of your existing code is required**. we recommend you to follow the [User Guide](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/user-guide/barcode-scanner.html) and re-write your codes.

-# Dynamsoft Barcode Reader JavaScript Edition Version 7.x Will Reach End of Support on December 31st 2023
-
-First released on August 09th, 2019, Dynamsoft Barcode Reader JavaScript Edition Version 7.x (DBR-JS 7) had 11 minor updates in total. Version 7.6.0 was the final version of DBR-JS 7 and it was released on September 1st, 2020.
-
-Based on Dynamsoft Lifetime Support Policy, Dynamsoft is committed to providing maintenance and support for all Dynamsoft product releases for TWO years from their general availability date.
-
-DBR-JS 7 was well accepted by hundreds of customers and we extended its maintenance and support after it had reached TWO years on August 31st, 2022. However, it will reach end of support by end of this year. This means that Dynamsoft will no longer be providing updates, bug fixes, or technical support for this version beyond 2023/12/31.
-
-Since the date is fast approaching, our system will stop serving new licenses for DBR-JS 7, including validity extensions or quota extensions. The license server that supports DBR-JS 7 will be taken offline by end of 2024. If you already have a license for DBR-JS 7 beyond that time and would like to keep using it, you can [contact us](https://www.dynamsoft.com/contact/).
-
-## Upgrade is recommended
-
-If you are still using DBR-JS 7, We strongly recommend that you upgrade to our latest v9.6, which offers many new features and improvements.
-
-### What's New?
-
-- Improved recognition success rate and speed for linear barcodes
-- Faster processing of continuous video frames
-- Improved camera control, especially on android devices. For example, auto zoom and auto focus.
-- Support for many more barcode types including Pharma Code, Code 11, MSI, etc.
-- Other features and bug fixes
-
-### Try Online Demo
-
-We invite you to try our [online demo](https://demo.dynamsoft.com/barcode-reader-js) to see the latest version in action.
-
-### Free Upgrade from v7 to v9
-
-If you have a subscription license, the upgrade is free of charge. Otherwise, you can [contact us](https://www.dynamsoft.com/contact/) for a paid upgrade.
-
-We understand that upgrading to a new version can be a significant undertaking. Our support team is available to assist you if you encounter any issues during the upgrade process.

-# How to Upgrade DBR-JS From v7.x To v9.x 
-
-## Change your license
-
-   Your v7.x license is not compatible with v9.x, you must [Contact Dynamsoft Sales Team](mailto:sales@dynamsoft.com) to acquire a new license key. If you have a subscription license or you have valid maintenance for a perpetual license, the upgrade is free of charge.
-
-## Update the version number if you are using a **CDN**
-
-   ```html
-   <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.6.42/dist/dbr.js"></script>
-   ```
-
-   > If you have deployed the library files to your own server, [download the latest version](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=upgradeguide) and replace the old files.
-
-## Update the API you use for licensing the SDK
-
-   In v7.x, you probably licensed the SDK with "data-productKeys" like this:
-
-   ```html
-   <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@7.x/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
-   ```
-
-   In v9.x, use the API `license` instead:
-
-   ```html
-   <script>
-      Dynamsoft.DBR.BarcodeScanner.license = 'YOUR-NEW-LICENSE-KEY';
-      //...
-   </script>
-   ```
-
-## Breaking Changes
-
-### :exclamation: *Namespace change*
-
-Use the new namespace `Dynamsoft.DBR` in place of just `Dynamsoft`. The following shows the equivalent changes for `BarcodeScanner` and `BarcodeReader`:
-
-```js
-Dynamsoft.BarcodeScanner -> Dynamsoft.DBR.BarcodeScanner
-Dynamsoft.BarcodeReader -> Dynamsoft.DBR.BarcodeReader
-```
-
-> If you are using the library as an ES/CMD module, you don't need to change your code.Otherwise, you can make a global change from `Dynamsoft` to `Dynamsoft.DBR` in your code.
-
-### API Changes
-
-After changing the namespace, check your code and see if you are using any of the APIs in the first column below. If found, change them to the equivalent shown in the second column:
-
-| API Name | Notes |
-|:-:|:-:|
-| `Dynamsoft.DBR.detectEnvironment()` | Use `Dynamsoft.DBR.BarcodeReader.detectEnvironment()` instead. |
-| `Dynamsoft.DBR.engineResourcePath` | Use `Dynamsoft.DBR.BarcodeReader.engineResourcePath` instead. |
-| `Dynamsoft.DBR.isLoaded()` | Use `Dynamsoft.DBR.BarcodeReader.isWasmLoaded()` instead. |
-| `Dynamsoft.DBR.loadWasm()` | Use `Dynamsoft.DBR.BarcodeReader.loadWasm()` instead. |
-| `Dynamsoft.DBR.productKeys` | Use `Dynamsoft.DBR.BarcodeReader.license` instead. |
-| `Dynamsoft.DBR.version` | Use `Dynamsoft.DBR.BarcodeReader.version` instead. |
-| `destroy()` | Use `destroyContext()` instead. |
-| `bDestroyed` | Use `isContextDestroyed()` instead. |
-| `onUnduplicatedRead` | Use `onUniqueRead` instead. |
-| `bPlaySoundOnSuccessfulRead` | Use `whenToPlaySoundforSuccessfulRead` in `ScanSettings` instead. |
-| `soundOnSuccessfulRead` | Use `soundOnSuccessfullRead` in `ScanSettings` instead. |
-| `bSaveOriCanvas` | Use `ifSaveOriginalImageInACanvas` instead. |
-| `oriCanvas` | Use `getOriginalImageInACanvas()` instead. |
-
-### `deblurLevel` is Deprecated
-
-`deblurLevel` has been replaced with `deblurModes`.
-
-Check out the code below on how to switch from `deblurLevel` to `deblurModes`.
-
-```js
-let settings = await barcodeScanner.getRuntimeSettings();
-//settings.deblurLevel = 9;
-settings.deblurModes = ["DM_DIRECT_BINARIZATION",   
-                        "DM_THRESHOLD_BINARIZATION", 
-                        "DM_GRAY_EQUALIZATION",
-                        "DM_SMOOTHING",
-                        "DM_MORPHING",
-                        "DM_DEEP_ANALYSIS",
-                        "DM_SHARPENING",
-                        "DM_SKIP"] 
-await barcodeScanner.updateRuntimeSettings(settings);
-```
-
-### Changed Class Names of the Built-in UI elements
-
-If you manipulated any of the built-in UI elements which are located by their class names, you need to update the class name(s) used in your code.
-
-| v7.x in **dbr.scanner.html** | v9.x in **dbr.ui.html**|
-|:-:|:-:|
-| `dbrScanner-bg-loading` | `dce-bg-loading` |
-| `dbrScanner-bg-camera` | `dce-bg-camera` |
-| `dbrScanner-video` | `dce-video` |
-| `dbrScanner-cvs-scanarea` | `dce-scanarea` |
-| `dbrScanner-scanlight` | `dce-scanlight` |
-| `dbrScanner-sel-camera` | `dce-sel-camera` |
-| `dbrScanner-sel-resolutio` | `dce-sel-resolution` |
-| `dbrScanner-btn-close` | `dce-btn-close` |
-
-### Other changes
-
-The file **dbr.scanner.html** has been renamed to **dbr.ui.html**.
-
-If you are still having issue with the upgrade, please [contact us](https://www.dynamsoft.com/contact/).

-   ```html
-   <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@9.3.33/dist/dbr.js"></script>
-   ```
-
-   > If you have deployed the library files to your own server, [download the latest version](https://www.dynamsoft.com/barcode-reader/downloads/?utm_source=upgradeguide) and replace the old files.
-
-2. Update the API you use for licensing the SDK
-
-Previously, you might have used the APIs `productKeys`, `handshakeCode`, `organizationID` and `sessionPassword`, etc. In v9.0.0+, use the API `license` instead.
-
-* If you used an offline license before, simply pass that license key using the API `license`.
-* If you used an online license before, you can log in the [customer portal](https://www.dynamsoft.com/customer/license/fullLicense) and check the according license key to be used with the API `license`.

-
-## Specify the barcode format
-
-Specifying the target barcode formats not only speeds up the recognition process but also improves accuracy. This is one of the most common customization needs. BarcodeScanner provides two ways to specify the barcode formats. For example, if your target formats are `QR_CODE` and `CODE_128`:
-
-> [!NOTE]
-> See [all supported barcode formats](https://dynamsoft.com/barcode-reader/barcode-types/).
-
-### Option 1: Set via BarcodeScannerConfig
-
-Add the following configuration in [`BarcodeScannerConfig`]({{ site.js_api }}barcode-scanner.html#barcodescannerconfig):
-
-```js
-const barcodeScanner = new Dynamsoft.BarcodeScanner({
-  // ...
-  barcodeFormats:[Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE , Dynamsoft.DBR.EnumBarcodeFormat.BF_CODE_128],
-  // ...
-});
-```
-
-### Option 2: Specify in a template file
-
-The benefit of this approach is that the template file can be reused across different platforms or programming languages, ensuring performance consistency across scenarios. To do this, follow these steps:
-
-1. Open `dist\DBR-PresetTemplates.json` in your code editor. This file contains all the preset templates related to barcode reading.
-
-2. Add the `BarcodeFormatIds` to the `BarcodeReaderTaskSettingOptions` object.
-
-3. Update `BarcodeFormatIds` as shown below. You can get barcode format strings [here](https://www.dynamsoft.com/capture-vision/docs/core/enums/barcode-reader/barcode-format.html).
-
-<img src="./assets/updateBarcodeFormat.png" alt="description" style="display: block; margin: 0 auto; width: 70%;"/>
-
-Refer to [`Use customized template`](#use-customized-template) for more details.
-
-> [!IMPORTANT]
-> Due to the powerful customization capabilities, the number of configurable parameters in the templates is extensive and relatively complex. feel free to [contact us](https://www.dynamsoft.com/contact/) if you need help creating a custom template.
-
-## Use customized template
-
-In more complex scenarios—such as blurred, damaged, curved, or unevenly lit barcodes—you might need a custom template to perform specific image processing steps. BarcodeScannerConfig provides a property to load a template file, allowing you to customize the algorithm’s processing workflow.
-
-> [!WARNING]
-> This operation will overwrite the built-in templates.
-
-```js
-  const barcodeScannerConfig = {
-    // The path to your custom JSON template that defines the scanning process.
-    templateFilePath:'path/to/DBR-PresetTemplates.json'
-    };
-  // Initialize the BarcodeScanner with the above BarcodeScannerConfig object
-  const barcodeScanner = new Dynamsoft.BarcodeScanner(barcodeScannerConfig);
-```
-
-## Config the Pre-built UIs
-
-The built-in UI of `BarcodeScanner` is composed of `BarcodeScannerView` and `BarcodeResultView`. In `MULTI_UNIQUE` mode, `BarcodeResultView` is shown by default to ensure the essential workflow can proceed. Other UI components can be shown or hidden manually through `barcodeScannerConfig`. Let's break down these two Views:
-
-### BarcodeScannerView
-
-The `BarcodeScannerView` is composed of the following UI elements:
-
-<img src="./assets/scannerView1103000.png" alt="description" style="display: block; margin: 0 auto; width: 35%;"/>
-
-1. **Camera View**: The Camera View is the camera viewfinder UI component within the `BarcodeScannerView`. This viewfinder occupies the majority of the space within the `BarcodeScannerView` to give the user a clear view and precise control of the image being scanned.
-
-2. **Load Image Button**: This button allows the user to scan a file of a barcode-containing image from the device's local storage. You can decide whether to show or hide the button by [showUploadImageButton]({{ site.js_api }}barcode-scanner.html#barcodescannerconfig) property.
-
-3. **Close Scanner Button**: This button closes the Barcode Scanner, return a [`BarcodeScanResult`]({{ site.js_api }}barcode-scanner.html#barcodescanresult) object and destroys the **`BarcodeScanner`** instance. You can decide whether to show or hide the button by [showCloseButton]({{ site.js_api }}barcode-scanner.html#scannerviewconfig) property.
-
-4. **Flash Button**: This button allows the user to toggle the camera's torch. You can decide whether to show or hide the button by [showFlashButton]({{ site.js_api }}barcode-scanner.html#barcodescannerconfig) property.
-
-5. **Camera Switch Button**: This button allows the users to change between cameras. You can specify the mode and visibility of the camera switch control by [cameraSwitchControl]({{ site.js_api }}barcode-scanner.html#scannerviewconfig) property.
-
-### BarcodeResultView (MULTI_UNIQUE mode only)
-
-Here is a quick breakdown of the `MULTI_UNIQUE` UI elements of the `BarcodeResultView` view:
-
-<img src="./assets/resultView.png" alt="description" style="display: block; margin: 0 auto; width: 35%;"/>
-
-1. **Barcode Results List**: The list used to display the decoding results.The list is updated whenever a new barcode is successfully decoded, or the same code is detected again after a specific [duplicateForgetTime]({{ site.js_api }}barcode-scanner.html#barcodescannerconfig).
-
-2. **Clear Button**: The button on the bottom left, which clears all elements of the current `Barcode Results List`. You can change the style of the Button with [BarcodeResultViewToolbarButtonsConfig]({{ site.js_api }}barcode-scanner.html#barcoderesultviewtoolbarbuttonsconfig).
-
-3. **Done Button**: The button on the bottom right, which closes the Barcode Scanner, return a [`BarcodeScanResult`]({{ site.js_api }}barcode-scanner.html#barcodescanresult) object that includes all unique barcodes and destroys the **`BarcodeScanner`** instance. You can change the style of the Button with [BarcodeResultViewToolbarButtonsConfig]({{ site.js_api }}barcode-scanner.html#barcoderesultviewtoolbarbuttonsconfig).
-
-### Manually modify the UI file
-
-Another way to fully customize the UI is by directly editing the `.xml` file. In the `dist/` directory, you'll find the `barcode-scanner.ui.xml` file, which is the default UI for the `BarcodeScanner`. 
-
-> [!NOTE]
-> Although it is essentially HTML, using a .xml extension can help prevent compatibility issues with the Live Server plugin.
-
-You can make a copy of it and apply your own modifications. For example, to double the size of the `UploadImage` icon, you can edit the file like this:
-
-```xml
-<template>
-<!-- ... -->
-    <!-- <svg id="upload-image" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="24" height="24" viewBox="0 0 26 26"> -->
-    <svg id="upload-image" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="48" height="48" viewBox="0 0 26 26">
-<!-- ... -->        
-</template>
-```
-
-Once you've made your changes, just set the new `uiPath` in the configuration. If everything is configured correctly, the updated UI will appear the next time you refresh the page.
-
-```js
-    const barcodeScanner = new Dynamsoft.BarcodeScanner({
-      //...
-      uiPath: "path/to/new-barcode-scanner.ui.xml?v=<your-update-version>",
-      //...
-    });
-```
-
-## Use BarcodeScanner in frameworks
-
-Integrating `BarcodeScanner` into frameworks like `Angular`, `React`, and `Vue` is a little different compared to native usage. You can also refer to [the ready-made samples for popular frameworks](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/barcode-scanner-api-samples/scan-single-barcode) directly without reading this guide.
-
-### Installation
-
-Open the terminal from your project root and install **Dynamsoft Barcode Reader SDK** with the following command:
-
-```sh
-npm install dynamsoft-barcode-reader-bundle@11.0.6000 -E
-```
-
-### Component for video decoding
-
-Here’s how to quickly set up a video barcode scanner using the `BarcodeScanner` class:
-
-```ts
-    const config = {
-      license: "YOUR-LICENSE-KEY",  // Replace with your license key
-    }
-    const barcodeScanner = new BarcodeScanner(config);
-    barcodeScanner.launch().then((result)=>{
-      console.log(result); // Handle the decoding result here
-    });
-```
-
-#### Define the resource paths
-
-To ensure stability, especially in environments with limited internet access, it’s a good idea to **host all required resources locally** (e.g., under the dist/ folder).
-Below is an example using the official CDN — feel free to replace it with your own path:
-
-```ts
-    const config = {
-      license: "YOUR-LICENSE-KEY",
-      // Configures the paths where the .wasm files and other necessary resources for modules are located.
-      engineResourcePaths: {
-        // Using jsDelivr CDN as an example
-        rootDirectory: "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.6000/dist/",
-      },
-      // Path to the UI (.xml template file).
-      uiPath: "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.6000/dist/barcode-scanner.ui.xml",
-    };
-```
-
-#### Set up the video container
-
-Specify the container where the scanner UI should be rendered:
-
-```ts
-    const config = {
-      container: ".barcode-scanner-view", // CSS selector for the scanner container
-    };
-```
-
-Make sure your HTML includes the corresponding element:
-
-```html
-<div class="barcode-scanner-view"></div>
-```
-
-The above steps cover the key considerations when using the `BarcodeScanner` component within a modern JavaScript framework. To recap:
-
-- Install the SDK with an exact version to avoid compatibility issues.
-
-- Define resource paths explicitly — either via CDN or local dist/ folder — to ensure consistent loading behavior.
-
-- Configure and launch the scanner using the provided component API.
-
-- Set up a container element to properly display the scanner UI.
-
-By following these best practices, you'll ensure a stable and reliable integration of `BarcodeScanner` into your application.

-</p>
-
-### Step 1: Setting up the HTML and Including the Barcode Scanner
-
-As outlined earlier, this guide will help you create a simple Hello World barcode scanning application using vanilla JavaScript. The full sample code is also available in the [GitHub repository](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/v11.0.30).
-
-The first step before writing the code is to include the SDK in your application. You can simply include the SDK by using the precompiled script.
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-  <body>
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-  </body>
-</html>
-```
-
-In this example, we include the precompiled Barcode Scanner SDK script via public CDN in the header.
-
-<div class="multi-panel-switching-prefix"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Use a public CDN</div>
-
-The simplest way to include the SDK is to use either the [**jsDelivr**](https://jsdelivr.com/) or [**UNPKG**](https://unpkg.com/) CDN.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-  ```
-
-When using a framework such as **React**, **Vue** or **Angular**, we recommend adding the package as a dependency using a package manager such as **npm** or **yarn**:
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.3000
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@11.0.3000
-  ```
-
-As for package managers like **npm** or **yarn**, you likely need to specify the location of the engine files as a link to a CDN. Please see the [BarcodeScannerConfig API](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig) for a code snippet on how to set the `engineResourcePaths`.
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Host the SDK yourself</div>
-
-Alternatively, you may choose to download the SDK and host the files on your own server or preferred CDN. This approach provides better control over versioning and availability.
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=11.0.30&utm_source=guide&product=dbr&package=js)
-
-  The resources are located in the `./dist/` directory.
-
-- From npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.3000
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You can copy it elsewhere and add `@<version>` tag.
-  
-  > [!IMPORTANT]
-  > Since "node_modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node_modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-You can typically include SDK like this:
-
-```html
-<script src="path/to/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-```
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-switching-end"></div>
-
-Barcode Scanner comes with a **Ready-to-Use UI**. When the Barcode Scanner launches, it creates a container which it populates with the **Ready-to-Use UI**.
-
-### Step 2: Initializing the Barcode Scanner
-
-```js
-// Initialize the Dynamsoft Barcode Scanner
-const barcodescanner = new Dynamsoft.BarcodeScanner({
-  // Please don't forget to replace YOUR_LICENSE_KEY_HERE
-  license: "YOUR_LICENSE_KEY_HERE", 
-});
-```
-
-This is the **simplest** way to initialize the Barcode Scanner. The configuration object must include a valid **license** key. Without it, the scanner will fail to launch and display an error. For help obtaining a license, see the [licensing](#license) section.
-
-> [!TIP]
-> By default, the `BarcodeScanner` scans a single barcode at a time. However, it also supports a `MULTI_UNIQUE` scanning mode, which continuously scans and accumulates unique results in real time. You can enable this mode by modifying the [`BarcodeScannerConfig`](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig) as follows:
-
-```js
-// Initialize the Dynamsoft Barcode Scanner in MULTI_UNIQUE mode
-const barcodescanner = new Dynamsoft.BarcodeScanner({
-  license: "YOUR_LICENSE_KEY_HERE",
-  scanMode: Dynamsoft.EnumScanMode.SM_MULTI_UNIQUE,
-});
-```
-
-### Step 3: Launching the Barcode Scanner
-
-```js
-(async () => {
-  // Launch the scanner and wait for the result
-  const result = await barcodescanner.launch();
-  // Display the first detected barcode's text in an alert
-  if (result.barcodeResults.length) {
-      alert(result.barcodeResults[0].text);
-  }
-})();
-```
-
-Now that the Barcode Scanner has been initialized and configured, it is ready to be launched! Upon launch, the Barcode Scanner presents the main **`BarcodeScannerView`** UI in its container on the page, and is ready to start scanning. By default, we use the `SINGLE` scanning mode, which means only one decoding result will be included in the final result. In the code above, we directly alerted the successfully decoded barcode text on the page.
-
-> [!NOTE]
-> In the Hello World sample, after a successfully decoding process, the scanner closes and the user is met with an empty page. In order to open the scanner again, the user must refresh the page. You may choose to implement a more user-friendly behavior in a production environment, such as presenting the user with an option to re-open the Barcode Scanner upon closing it.

-</p>
-
-### Step 1: Setting up the HTML and Including the Barcode Scanner
-
-As outlined earlier, this guide will help you create a simple Hello World barcode scanning application using vanilla JavaScript. The full sample code is also available in the [GitHub repository](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/v11.0.60).
-
-The first step before writing the code is to include the SDK in your application. You can simply include the SDK by using the precompiled script.
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-  <body>
-    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-  </body>
-</html>
-```
-
-In this example, we include the precompiled Barcode Scanner SDK script via public CDN in the header.
-
-<div class="multi-panel-switching-prefix"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Use a public CDN</div>
-
-The simplest way to include the SDK is to use either the [**jsDelivr**](https://jsdelivr.com/) or [**UNPKG**](https://unpkg.com/) CDN.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-  ```
-
-When using a framework such as **React**, **Vue** or **Angular**, we recommend adding the package as a dependency using a package manager such as **npm** or **yarn**:
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.6000
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@11.0.6000
-  ```
-
-As for package managers like **npm** or **yarn**, you likely need to specify the location of the engine files as a link to a CDN. Please see the [BarcodeScannerConfig API](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig) for a code snippet on how to set the `engineResourcePaths`.
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Host the SDK yourself</div>
-
-Alternatively, you may choose to download the SDK and host the files on your own server or preferred CDN. This approach provides better control over versioning and availability.
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=11.0.60&utm_source=guide&product=dbr&package=js)
-
-  The resources are located in the `./dist/` directory.
-
-- From npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.6000
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You can copy it elsewhere and add `@<version>` tag.
-  
-  > [!IMPORTANT]
-  > Since "node_modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node_modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-You can typically include SDK like this:
-
-```html
-<script src="path/to/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-```
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-switching-end"></div>
-
-Barcode Scanner comes with a **Ready-to-Use UI**. When the Barcode Scanner launches, it creates a container which it populates with the **Ready-to-Use UI**.
-
-### Step 2: Initializing the Barcode Scanner
-
-```js
-// Initialize the Dynamsoft Barcode Scanner
-const barcodescanner = new Dynamsoft.BarcodeScanner({
-  // Please don't forget to replace YOUR_LICENSE_KEY_HERE
-  license: "YOUR_LICENSE_KEY_HERE", 
-});
-```
-
-This is the **simplest** way to initialize the Barcode Scanner. The configuration object must include a valid **license** key. Without it, the scanner will fail to launch and display an error. For help obtaining a license, see the [licensing](#license) section.
-
-> [!TIP]
-> By default, the `BarcodeScanner` scans a single barcode at a time. However, it also supports a `MULTI_UNIQUE` scanning mode, which continuously scans and accumulates unique results in real time. You can enable this mode by modifying the [`BarcodeScannerConfig`](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig) as follows:
-
-```js
-// Initialize the Dynamsoft Barcode Scanner in MULTI_UNIQUE mode
-const barcodescanner = new Dynamsoft.BarcodeScanner({
-  license: "YOUR_LICENSE_KEY_HERE",
-  scanMode: Dynamsoft.EnumScanMode.SM_MULTI_UNIQUE,
-});
-```
-
-### Step 3: Launching the Barcode Scanner
-
-```js
-(async () => {
-  // Launch the scanner and wait for the result
-  const result = await barcodescanner.launch();
-  // Display the first detected barcode's text in an alert
-  if (result.barcodeResults.length) {
-      alert(result.barcodeResults[0].text);
-  }
-})();
-```
-
-Now that the Barcode Scanner has been initialized and configured, it is ready to be launched! Upon launch, the Barcode Scanner presents the main **`BarcodeScannerView`** UI in its container on the page, and is ready to start scanning. By default, we use the `SINGLE` scanning mode, which means only one decoding result will be included in the final result. In the code above, we directly alerted the successfully decoded barcode text on the page.
-
-> [!NOTE]
-> In the Hello World sample, after a successfully decoding process, the scanner closes and the user is met with an empty page. In order to open the scanner again, the user must refresh the page. You may choose to implement a more user-friendly behavior in a production environment, such as presenting the user with an option to re-open the Barcode Scanner upon closing it.

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#filter-the-results-important) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```

-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=10.0.20&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the [MediaDevices: getUserMedia()](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) method only works in secure contexts (HTTPS), in some or all supporting browsers.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-2. IIS: [How to create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-3. Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)

-
-## Building your own page
-
-### Include the SDK
-
-To utilize the SDK, the initial step involves including the corresponding resource files:
-
-* `core.js` encompasses common classes, interfaces, and enumerations that are shared across all Dynamsoft SDKs.
-* `license.js` introduces the `LicenseManager` class, which manages the licensing for all Dynamsoft SDKs.
-* `utility.js` encompasses auxiliary classes that are shared among all Dynamsoft SDKs.
-* `dbr.js` defines interfaces and enumerations specifically tailored to the barcode reader module.
-* `cvr.js` introduces the `CaptureVisionRouter` class, which governs the entire image processing workflow.
-* `dce.js` comprises classes that offer camera support and basic user interface functionalities.
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-core@3.0.32/dist/core.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-license@3.0.20/dist/license.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-utility@1.0.21/dist/utility.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.0.20/dist/dbr.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-router@2.0.31/dist/cvr.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-camera-enhancer@4.0.1/dist/dce.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-core@3.0.32/dist/core.js"></script>
-  <script src="https://unpkg.com/dynamsoft-license@3.0.20/dist/license.js"></script>
-  <script src="https://unpkg.com/dynamsoft-utility@1.0.21/dist/utility.js"></script>
-  <script src="https://unpkg.com/dynamsoft-barcode-reader@10.0.20/dist/dbr.js"></script>
-  <script src="https://unpkg.com/dynamsoft-capture-vision-router@2.0.31/dist/cvr.js"></script>
-  <script src="https://unpkg.com/dynamsoft-camera-enhancer@4.0.1/dist/dce.js"></script>
-  ```
-
-In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-- https://download2.dynamsoft.com/packages/dynamsoft-core@3.0.32/dist/core.js
-- https://download2.dynamsoft.com/packages/dynamsoft-license@3.0.20/dist/license.js
-- https://download2.dynamsoft.com/packages/dynamsoft-utility@1.0.21/dist/utility.js
-- https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader@10.0.20/dist/dbr.js
-- https://download2.dynamsoft.com/packages/dynamsoft-capture-vision-router@2.0.31/dist/cvr.js
-- https://download2.dynamsoft.com/packages/dynamsoft-camera-enhancer@4.0.1/dist/dce.js
-
-However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself.
-
-#### Host the SDK yourself
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=10.0.20&utm_source=guide&product=dbr&package=js)

-  npm install dynamsoft-image-processing@2.0.30 --save
-  ```
-
-Depending on how you downloaded the SDK and how you intend to use it, you can typically include it like this:
-
-```html
-<script src="./dynamsoft/distributables/dynamsoft-core@3.0.32/dist/core.js"></script>
-<script src="./dynamsoft/distributables/dynamsoft-license@3.0.20/dist/license.js"></script>

-<script src="./dynamsoft/distributables/dynamsoft-capture-vision-router@2.0.31/dist/cvr.js"></script>
-<script src="./dynamsoft/distributables/dynamsoft-camera-enhancer@4.0.1/dist/dce.js"></script>
-```
-
-or
-
-```html
-<script src="/node_modules/dynamsoft-core/dist/core.js"></script>
-<script src="/node_modules/dynamsoft-license/dist/license.js"></script>
-<script src="/node_modules/dynamsoft-utility/dist/utility.js"></script>
-<script src="/node_modules/dynamsoft-barcode-reader/dist/dbr.js"></script>
-<script src="/node_modules/dynamsoft-capture-vision-router/dist/cvr.js"></script>
-<script src="/node_modules/dynamsoft-camera-enhancer/dist/dce.js"></script>
-```
-
-or
-
-```typescript
-import { CoreModule, EnumCapturedResultItemType } from 'dynamsoft-core'
-import { LicenseManager } from 'dynamsoft-license';
-import { CapturedResultReceiver, CaptureVisionRouter, type SimplifiedCaptureVisionSettings } from "dynamsoft-capture-vision-router";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-import { DecodedBarcodesResult } from 'dynamsoft-barcode-reader';
-import { MultiFrameResultCrossFilter } from 'dynamsoft-utility';
-```
-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the following resources for guidance:
-     1. [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-     2. [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-     3. [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=10.0.20&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### Specify the location of the "engine" files (optional)
-
-This is usually only required with frameworks like Angular or React, etc. where the referenced JavaScript files such as `cvr.js`, `dbr.js` are compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `Dynamsoft.Core.CoreModule.engineResourcePaths`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Dynamsoft.Core.CoreModule.engineResourcePaths.core = "https://cdn.jsdelivr.net/npm/dynamsoft-core@3.0.32/dist/";
-Dynamsoft.Core.CoreModule.engineResourcePaths.license = "https://cdn.jsdelivr.net/npm/dynamsoft-license@3.0.20/dist/";
-Dynamsoft.Core.CoreModule.engineResourcePaths.dbr = "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.0.20/dist/";
-Dynamsoft.Core.CoreModule.engineResourcePaths.cvr = "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-router@2.0.31/dist/";
-Dynamsoft.Core.CoreModule.engineResourcePaths.dce = "https://cdn.jsdelivr.net/npm/dynamsoft-camera-enhancer@4.0.1/dist/";
-Dynamsoft.Core.CoreModule.engineResourcePaths.std = "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-std@1.0.0/dist/";
-Dynamsoft.Core.CoreModule.engineResourcePaths.dip = "https://cdn.jsdelivr.net/npm/dynamsoft-image-processing@2.0.30/dist/"
-```
-
-### Set up and start image processing
-
-#### Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm(["cvr", "dbr"]);
-```
-
-#### Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `tempRouter` in the following code
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let tempRouter = null;
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (tempRouter = tempRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-#### Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-        // In this example, the barcode result is shown on the page beneath the video
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onDecodedBarcodesReceived: (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-        // In this example, the barcode result is shown on the page beneath the video
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/core/basic-structures/captured-result-receiver.html) for more information.
-
-#### Start the process
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans a single barcode.                                        |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-### Customize the process
-
-#### Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-##### Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds =
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html).
-
-##### Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes |= 
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes = 
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE |
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-resultReceiver.onCapturedResultReceived = (result) => {
-  let barcodes = result.items.filter((item) =>
-    item.type === Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE
-  );
-  if (barcodes.length > 0) {
-    let image = result.items.filter((item) =>
-      item.type === Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-    // The image that we found the barcode(s) on.
-  }
-};
-```
-
-##### Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-##### Specify a scan region
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-While the code above accomplishes the task, a more effective approach is to restrict the scan region directly at the image source, as demonstrated in the following code snippet.
-
-> * With the region configured at the image source, the images are cropped right before they are gathered for processing, eliminating the necessity to modify the processing settings further.
-> * `cameraEnhancer` elevates interactivity by overlaying a mask on the video, providing a clear delineation of the scanning region.
-> * See also: [CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-#### Edit the preset templates directly
-
-The preset templates have a lot more settings that can be customized to best suit your use case. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-10.0.20/dynamsoft/resources/barcode-reader/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); //e.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the
-```
-
-#### Filter the results (Important)
-
-While processing video frames, it's common for the same barcode to be detected multiple times. To enhance the user experience, we can use [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object, having two options currently at our disposal:
-
-##### Option 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification(Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-##### Option 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication(Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.0.20 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime(5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification(Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true);
-filter.enableResultDeduplication(Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true);
-filter.setDuplicateForgetTime(5000);
-await cvRouter.addResultFilter(filter);
-```
-
-#### Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-### Customize the UI
-
-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html#customize-the-ui).
-
-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.0.20](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.0.20).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |
-  | :----------: | :--------------: |
-  |    Chrome    | v78+<sup>1</sup> |
-  |   Firefox    | v62+<sup>1</sup> |
-  |     Edge     |       v79+       |
-  |    Safari    |       v14+       |
-
-  <sup>1</sup> devices running iOS needs to be on iOS 14.3+ for camera video streaming to work in Chrome, Firefox or other Apps using webviews.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#filter-the-results-important) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```
-

-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=10.0.21&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/pL4e7yrd/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the [MediaDevices: getUserMedia()](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) method only works in secure contexts (HTTPS), in some or all supporting browsers.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-2. IIS: [How to create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-3. Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)
-4. Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-If the test doesn't go as expected, you can [contact us](https://www.dynamsoft.com/company/contact/?ver=10.0.21&utm_source=guide&product=dbr&package=js).
-
-## Building your own page
-
-### Include the SDK
-
-To utilize the SDK, the initial step involves including the corresponding resource files:
-
-* `core.js` encompasses common classes, interfaces, and enumerations that are shared across all Dynamsoft SDKs.
-* `license.js` introduces the `LicenseManager` class, which manages the licensing for all Dynamsoft SDKs.
-* `utility.js` encompasses auxiliary classes that are shared among all Dynamsoft SDKs.
-* `dbr.js` defines interfaces and enumerations specifically tailored to the barcode reader module.
-* `cvr.js` introduces the `CaptureVisionRouter` class, which governs the entire image processing workflow.
-* `dce.js` comprises classes that offer camera support and basic user interface functionalities.
-
-For simplification, starting from version 10.0.21, we introduced `dbr.bundle.js`. Including this file is equivalent to incorporating all six packages.
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-core@3.0.33/dist/core.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-license@3.0.40/dist/license.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-utility@1.0.21/dist/utility.js"></script>
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.0.21/dist/dbr.js"></script>

-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-camera-enhancer@4.0.1/dist/dce.js"></script>
-  ```
-
-  Or just
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.0.21/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG  
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-core@3.0.33/dist/core.js"></script>

-  ```
-
-In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-- https://download2.dynamsoft.com/packages/dynamsoft-core@3.0.33/dist/core.js
-- https://download2.dynamsoft.com/packages/dynamsoft-license@3.0.40/dist/license.js

-- or bundle: https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader@10.0.21/dist/dbr.bundle.js
-
-However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself.
-
-#### Host the SDK yourself (optional)
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-Options to download the SDK:
-

-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the following resources for guidance:
-     1. [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-     2. [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-     3. [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=10.0.21&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### Specify the location of the "engine" files (optional)
-
-This is usually only required with frameworks like Angular or React, etc. where the referenced JavaScript files such as `cvr.js`, `dbr.js` are compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `Dynamsoft.Core.CoreModule.engineResourcePaths`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Object.assign(Dynamsoft.Core.CoreModule.engineResourcePaths, {
-  std: "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-std@1.0.0/dist/",
-  dip: "https://cdn.jsdelivr.net/npm/dynamsoft-image-processing@2.0.30/dist/",
-  core: "https://cdn.jsdelivr.net/npm/dynamsoft-core@3.0.33/dist/",
-  license: "https://cdn.jsdelivr.net/npm/dynamsoft-license@3.0.40/dist/",
-  cvr: "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-router@2.0.32/dist/",
-  dbr: "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.0.21/dist/",
-  dce: "https://cdn.jsdelivr.net/npm/dynamsoft-camera-enhancer@4.0.1/dist/"
-});
-```
-
-### Set up and start image processing
-
-#### Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm(["cvr", "dbr"]);
-```
-
-#### Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pRouter` in the following code:
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let pCvRouter = null; // promise of router
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (pCvRouter = pCvRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-#### Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode result is shown on the page beneath the video
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onDecodedBarcodesReceived: (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode result is shown on the page beneath the video
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/captured-result-receiver.html) for more information.
-
-#### Start the process
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans a single barcode.                                        |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-Read more on the [preset CaptureVisionTemplates](./preset-templates.md).
-
-### Customize the process
-
-#### Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-##### Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds =
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html).
-
-##### Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes |= 
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes = 
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE |
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-resultReceiver.onCapturedResultReceived = (result) => {
-  let barcodes = result.items.filter((item) =>
-      item.type === Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE
-  );
-  if (barcodes.length > 0) {
-    let image = result.items.filter(
-      (item) =>
-        item.type ===
-        Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-    // The image that we found the barcode(s) on.
-  }
-};
-```
-
-##### Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-##### Specify a scan region
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-While the code above accomplishes the task, a more effective approach is to restrict the scan region directly at the image source, as demonstrated in the following code snippet.
-
-> * With the region configured at the image source, the images are cropped right before they are gathered for processing, eliminating the necessity to modify the processing settings further.
-> * `cameraEnhancer` elevates interactivity by overlaying a mask on the video, providing a clear delineation of the scanning region.
-> * See also: [CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-#### Edit the preset templates directly
-
-The preset templates have a lot more settings that can be customized to best suit your use case. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-10.0.21/dynamsoft/resources/barcode-reader/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); //e.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the
-```
-
-#### Filter the results (Important)
-
-While processing video frames, it's common for the same barcode to be detected multiple times. To enhance the user experience, we can use [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object, having two options currently at our disposal:
-
-##### Option 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification(
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true
-);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-##### Option 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication(
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true
-);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.0.21 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime(5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification(
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true
-);
-filter.enableResultDeduplication(
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_BARCODE, true
-);
-filter.setDuplicateForgetTime(5000);
-await cvRouter.addResultFilter(filter);
-```
-
-#### Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-### Customize the UI

-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html#customize-the-ui).
-
-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.0.21](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.0.21).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |
-  | :----------: | :--------------: |
-  |    Chrome    | v78+<sup>1</sup> |
-  |   Firefox    | v62+<sup>1</sup> |
-  |     Edge     |       v79+       |
-  |    Safari    |       v14+       |
-
-  <sup>1</sup> devices running iOS needs to be on iOS 14.3+ for camera video streaming to work in Chrome, Firefox or other Apps using webviews.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.
-
-## How to Upgrade
-
-If you want to upgrade the SDK from an old version to a newer one, please see [how to upgrade](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/upgrade-guide/index.html?ver=10.0.21&utm_source=guide).

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-**Basic Requirements**
-  - Internet connection
-  - [A supported browser](#system-requirements)
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below
-

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `Dynamsoft.Core.CoreModule.loadWasm(["dbr"])`: This is an optional code. Used to load wasm resources in advance, reducing latency between video playing and barcode decoding.
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#filter-the-results-important) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```
-
-> Read more on [Capture Vision Router](https://www.dynamsoft.com/capture-vision/docs/core/architecture/#capture-vision-router).
-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=10.2.10&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/csm2f9wb/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.
-
-*Note*:
-
-If you open the web page as `file:///` or `http://` , the camera may not work correctly because the [MediaDevices: getUserMedia()](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) method only works in secure contexts (HTTPS), in some or all supporting browsers.
-
-To make sure your web application can access the camera, please configure your web server to support HTTPS. The following links may help.
-
-1. NGINX: [Configuring HTTPS servers](https://nginx.org/en/docs/http/configuring_https_servers.html)
-2. IIS: [How to create a Self Signed Certificate in IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/)
-3. Tomcat: [Setting Up SSL on Tomcat in 5 minutes](https://dzone.com/articles/setting-ssl-tomcat-5-minutes)
-4. Node.js: [npm tls](https://nodejs.org/docs/v0.4.1/api/tls.html)
-
-If the test doesn't go as expected, you can [contact us](https://www.dynamsoft.com/company/contact/?ver=10.2.10&utm_source=guide&product=dbr&package=js).
-
-## Building your own page
-
-### Include the SDK
-
-To utilize the SDK, the initial step involves including the corresponding resource files:
-
-* `core.js` encompasses common classes, interfaces, and enumerations shared across all Dynamsoft SDKs.
-* `license.js` introduces the `LicenseManager` class, which manages the licensing for all Dynamsoft SDKs.
-* `utility.js` encompasses auxiliary classes shared among all Dynamsoft SDKs.
-* `dbr.js` defines interfaces and enumerations tailored to the barcode reader module.
-* `cvr.js` introduces the `CaptureVisionRouter` class, which governs the entire image processing workflow.
-* `dce.js` comprises classes that offer camera support and basic user interface functionalities.
-
-To simplify things, starting from version 10.0.21, we introduced `dbr.bundle.js`, which combines all six of the above files. In the following chapters, we will use `dbr.bundle.js`.
-
-#### Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@10.2.1000/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@10.2.1000/dist/dbr.bundle.js"></script>
-  ```
-
-- In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-  ```html
-  <script src="https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader-bundle@10.2.1000/dist/dbr.bundle.js"></script>
-  ```
-
-  However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself.
-
-- In frameworks like React and Vue, you may want to add the package as a dependency.
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@10.2.1000 -E
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@10.2.1000 -E
-  ```
-
-  NOTE that in frameworks, you need to [specify the engineResourcePaths](#specify-the-location-of-the-engine-files-optional).
-
-#### Host the SDK yourself (optional)
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-There are two options for downloading the SDK, and the usage for each is slightly different
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=10.2.10&utm_source=guide&product=dbr&package=js)
-
-  The resources are located at path `dynamsoft/distributables/<pkg>@<version>`, you can typically include it like this:
-
-  ```html
-  <script src="dynamsoft/distributables/dynamsoft-barcode-reader-bundle@10.2.1000/dist/dbr.bundle.js"></script>
-  ```
-
-- npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@10.2.1000 -E
-  # Compared with using CDN, you need to set up more resources.
-  npm i dynamsoft-capture-vision-std@1.2.10 -E
-  npm i dynamsoft-image-processing@2.2.30 -E
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`, so the script would be like:
-
-  ```html
-  <script src="node_modules/dynamsoft-barcode-reader-bundle/dist/dbr.bundle.js"></script>
-  ```
-  
-  Since the version tags (`@<version>`) are missing, you need to [specify the engineResourcePaths](#specify-the-location-of-the-engine-files-optional) so that the SDK can find the resources correctly.
-
-  > To avoid confusion, we suggest renaming "node_modules" or moving "dynamsoft-" packages elsewhere for self-hosting, as "node_modules" is reserved for Node.js dependencies.
-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the following resources for guidance:
-     1. [Apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings)
-     2. [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap)
-     3. [Nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types)
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```cmd
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=10.2.10&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### Specify the location of the "engine" files (optional)
-
-This is usually only required with frameworks like Angular or React, etc. where the referenced JavaScript files such as `cvr.js`, `dbr.js` are compiled into another file.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.). The API is called `Dynamsoft.Core.CoreModule.engineResourcePaths`:
-
-```javascript
-//The following code uses the jsDelivr CDN, feel free to change it to your own location of these files
-Object.assign(Dynamsoft.Core.CoreModule.engineResourcePaths, {
-  std: "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-std@1.2.10/dist/",
-  dip: "https://cdn.jsdelivr.net/npm/dynamsoft-image-processing@2.2.30/dist/",
-  core: "https://cdn.jsdelivr.net/npm/dynamsoft-core@3.2.30/dist/",
-  license: "https://cdn.jsdelivr.net/npm/dynamsoft-license@3.2.21/dist/",
-  cvr: "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-router@2.2.30/dist/",
-  dbr: "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.2.10/dist/",
-  dce: "https://cdn.jsdelivr.net/npm/dynamsoft-camera-enhancer@4.0.3/dist/"
-});
-```
-
-### Set up and start image processing
-
-#### Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm(["dbr"]);
-```
-
-#### Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pCvRouter` in the following code:
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let pCvRouter = null; // The helper variable which is a promise of cvRouter
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (pCvRouter = pCvRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-#### Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-#### Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onDecodedBarcodesReceived: (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/captured-result-receiver.html) for more information.
-
-#### Start the process
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans a single barcode.                                        |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-Read more on the [preset CaptureVisionTemplates](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/preset-templates.html).
-
-### Customize the process
-
-#### Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-##### Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds =
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html).
-
-##### Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes |= 
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes = 
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE |
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-const EnumCRIT = Dynamsoft.Core.EnumCapturedResultItemType;
-resultReceiver.onCapturedResultReceived = (result) => {
-  let barcodes = result.items.filter(item => item.type === EnumCRIT.CRIT_BARCODE);
-  if (barcodes.length > 0) {
-    // Use a filter to get the image on which barcodes are found.
-    let image = result.items.filter(
-      item => item.type === EnumCRIT.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-  }
-};
-```
-
-##### Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-##### Specify a scan region
-
-We can specify a scan region to allow the SDK to process only part of the image, improving processing speed. The code snippet below demonstrates how to do this using the `cameraEnhancer` image source.
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-// In this example, we set the scan region to cover the central 25% of the image.
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-*Note*:
-
-1. By configuring the region at the image source, images are cropped before processing, removing the need to adjust any further processing settings.
-2. `cameraEnhancer` enhances interactivity by overlaying a mask on the video, clearly marking the scanning region.
-
-*See Also*:
-
-[CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-<!-- Since DCE is always used, no need to use this approach
-
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-``` -->
-
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-#### Edit the preset templates directly
-
-The preset templates have many more settings that can be customized to suit your use case best. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-10.2.10/dynamsoft/resources/barcode-reader/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); // E.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the template JSON file.
-```
-
-#### Filter the results (Important)
-
-While processing video frames, it's common for the same barcode to be detected multiple times. To enhance the user experience, we can use [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object, having two options currently at our disposal:
-
-##### Option 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-##### Option 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.2.10 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime(5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-filter.enableResultDeduplication("barcode", true);
-filter.setDuplicateForgetTime(5000);
-await cvRouter.addResultFilter(filter);
-```
-
-#### Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-### Customize the UI
-
-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html#customize-the-ui).
-
-## API Documentation
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.2.10](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.2.10).
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |
-  | :----------: | :--------------: |
-  |    Chrome    | v78+<sup>1</sup> |
-  |   Firefox    | v62+<sup>1</sup> |
-  |     Edge     |       v79+       |
-  |    Safari    |       v14+       |
-
-  <sup>1</sup> devices running iOS needs to be on iOS 14.3+ for camera video streaming to work in Chrome, Firefox or other Apps using webviews.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-**Basic Requirements**
-  - Internet connection
-  - A supported browser
-  - Camera access
-
-### Understand the code
-
-The complete code of the "Hello World" example is shown below
-
-```html

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#specify-the-license).
-
-- `Dynamsoft.Core.CoreModule.loadWasm(["dbr"])`: This is an optional code. Used to load wasm resources in advance, reducing latency between video playing and barcode decoding.
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#filter-the-results-important) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```
-
-> Read more on [Capture Vision Router](https://www.dynamsoft.com/capture-vision/docs/core/architecture/#capture-vision-router).
-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=10.4.30&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/csm2f9wb/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.
-
-> *Secure Contexts*:
->
-> If you open the web page as `http://` , our SDK may not work correctly because the [MediaDevices: getUserMedia()](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) and other methods only work in [secure contexts](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts) (HTTPS, `localhost`, `127.0.0.1`, `file://`), in some or all supporting browsers.
->
-> Regarding configuring https on your server, these guides for [nginx](https://nginx.org/en/docs/http/configuring_https_servers.html) / [IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/) / [tomcat](https://dzone.com/articles/setting-ssl-tomcat-5-minutes) / [nodejs](https://nodejs.org/docs/v0.4.1/api/tls.html) might help.

-
-## Preparing the SDK
-
-### Step 1: Include the SDK
-
-#### Option 1: Use a public CDN
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@10.4.2002/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@10.4.2002/dist/dbr.bundle.js"></script>
-  ```
-
-- In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-  ```html
-  <script src="https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader-bundle@10.4.2002/dist/dbr.bundle.js"></script>
-  ```
-
-  However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself.
-
-- In frameworks like React, Vue and Angular, you may want to add the package as a dependency.
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@10.4.2002 -E
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@10.4.2002 -E
-  ```
-
-  NOTE that in frameworks, you need to [specify the engineResourcePaths](#specify-the-location-of-the-engine-files-optional).
-
-#### Option 2: Host the SDK yourself (optional)
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=10.4.20&utm_source=guide&product=dbr&package=js)
-
-  The resources are located at path `dynamsoft/distributables/<pkg>@<version>`.
-
-- From npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@10.4.2002 -E
-  # Compared with using CDN, you need to set up more resources.
-  npm i dynamsoft-capture-vision-std@1.4.10 -E
-  npm i dynamsoft-image-processing@2.4.20 -E
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You must copy "dynamsoft-xxx" packages elsewhere and add `@<version>`. The `<version>` can be obtained from `package.json` of each package. Another thing to do is to [specify the engineResourcePaths](#2-optional-specify-the-location-of-the-engine-files) so that the SDK can correctly locate the resources.
-  > Since "node_modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node_modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-You can typically include SDK like this:
-
-```html
-<script src="path/to/dynamsoft-barcode-reader-bundle@10.4.2002/dist/dbr.bundle.js"></script>
-```
-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the guides for [apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings) / [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap) / [nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types).
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Step 2: Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### 1. Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=10.4.20&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### 2. [Optional] Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular, React or Vue.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.).
-
-```ts
-// in framework
-import { CoreModule } from "dynamsoft-barcode-reader-bundle";
-CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-```js
-// in pure js
-Dynamsoft.Core.CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-These code uses the jsDelivr CDN as an example, feel free to change it to your own location.
-
-## Using the SDK
-
-### Step 1: Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm(["dbr"]);
-```
-
-### Step 2: Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pCvRouter` in the following code:
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let pCvRouter = null; // The helper variable which is a promise of cvRouter
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (pCvRouter = pCvRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-### Step 3: Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-### Step 4: Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. This time we use `onCapturedResultReceived`:
-<!--In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:-->
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onCapturedResultReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onCapturedResultReceived: (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/captured-result-receiver.html) for more information.
-
-### Step 5: Start process video frames
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans multiple barcodes by default setting.                    |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-Read more on the [preset CaptureVisionTemplates](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/preset-templates.html).
-
-## Customizing the process
-
-### 1. Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-#### 1.1. Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds =
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html).
-
-#### 1.2. Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes |= 
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes = 
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE |
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-const EnumCRIT = Dynamsoft.Core.EnumCapturedResultItemType;
-resultReceiver.onCapturedResultReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    // Use a filter to get the image on which barcodes are found.
-    let image = result.items.filter(
-      item => item.type === EnumCRIT.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-  }
-};
-```
-
-#### 1.3. Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-#### 1.4. Specify a scan region
-
-We can specify a scan region to allow the SDK to process only part of the image, improving processing speed. The code snippet below demonstrates how to do this using the `cameraEnhancer` image source.
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-// In this example, we set the scan region to cover the central 25% of the image.
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-*Note*:
-
-1. By configuring the region at the image source, images are cropped before processing, removing the need to adjust any further processing settings.
-2. `cameraEnhancer` enhances interactivity by overlaying a mask on the video, clearly marking the scanning region.
-
-*See Also*:
-
-[CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-<!-- Since DCE is always used, no need to use this approach
-
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-``` -->
-
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-### 2. Edit the preset templates directly
-
-The preset templates have many more settings that can be customized to suit your use case best. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-10.4.2002/dynamsoft/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); // E.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the template JSON file.
-```
-
-### 3. [Important] Filter the results
-
-When processing video frames, the same barcode is often detected multiple times. To improve the user experience, we can use the [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object. This object provides two methods for handling duplicate detections, which can be used independently or together, depending on what best suits your application needs:
-
-#### Method 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-#### Method 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.2.10 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime(5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-filter.enableResultDeduplication("barcode", true);
-filter.setDuplicateForgetTime(5000);
-await cvRouter.addResultFilter(filter);
-```
-
-### 4. Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-## Customizing the UI
-
-```javascript
-// Create a CameraView instance with default settings
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-// Create a CameraView instance with a specified HTML file path, typically a local or remote URL
-let cameraView1 = await Dynamsoft.DCE.CameraView.createInstance('@engineResourcePath/dce.mobile-native.ui.html');
-// Create a CameraView instance within a specified DOM element
-let cameraView2 = await Dynamsoft.DCE.CameraView.createInstance(document.getElementById('my-ui'));
-// Create a CameraView instance using a custom UI file path
-let cameraView3 = await Dynamsoft.DCE.CameraView.createInstance('url/to/my/ui.html');
-
-// Get the UI element associated with the cameraView instance
-let uiElement = cameraView.getUIElement();
-// Remove the camera selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-camera').remove();
-// Remove the resolution selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-resolution').remove();
-```
-
-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/ui-customization-js.html?lang=js).

-## Documentation
-
-### API Reference
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.4.2002](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.4.2002).
-
-<!--  Compatibility is basically not an issue. Pls remove to another place
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |
-  | :----------: | :--------------: |
-  |    Chrome    | v78+<sup>1</sup> |
-  |   Firefox    | v68+<sup>1</sup> |
-  |     Edge     |       v79+       |
-  |    Safari    |       v14+       |
-
-  <sup>1</sup> devices running iOS needs to be on iOS 14.3+ for camera video streaming to work in Chrome, Firefox or other Apps using webviews.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#1-specify-the-license).
-
-- `Dynamsoft.Core.CoreModule.loadWasm(["dbr"])`: This is an optional code. Used to load wasm resources in advance, reducing latency between video playing and barcode decoding.
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#step-4-register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#3-important-filter-the-results) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```
-
-> Read more on [Capture Vision Router](https://www.dynamsoft.com/capture-vision/docs/core/architecture/#capture-vision-router).
-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=10.4.31&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/csm2f9wb/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.

-## Preparing the SDK
-
-### Step 1: Include the SDK
-
-<div class="multi-panel-switching-prefix"></div>
-<!-- 
-- [Use a public CDN](#useapubliccdn)
-- [Host the SDK yourself](#hostthesdkyourself) -->
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Use a public CDN</div>
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@10.4.3100/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@10.4.3100/dist/dbr.bundle.js"></script>
-  ```
-
-<!-- - In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-  ```html
-  <script src="https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader-bundle@10.4.3100/dist/dbr.bundle.js"></script>
-  ```
-
-  However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself. -->
-
-- In frameworks like React, Vue and Angular, you may want to add the package as a dependency.
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@10.4.3100 -E
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@10.4.3100 -E
-  ```
-
-  NOTE that in frameworks, you need to [specify the location of the engine files](#2-optional-specify-the-location-of-the-engine-files).
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Host the SDK yourself</div>
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=10.4.31&utm_source=guide&product=dbr&package=js)
-
-  The resources are located at path `dynamsoft/distributables/<pkg>@<version>`.
-
-- From npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@10.4.3100 -E
-  # Compared with using CDN, you need to set up more resources.
-  npm i dynamsoft-capture-vision-std@1.4.21 -E
-  npm i dynamsoft-image-processing@2.4.31 -E
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You must copy "dynamsoft-xxx" packages elsewhere and add `@<version>`. The `<version>` can be obtained from `package.json` of each package. Another thing to do is to [specify the engineResourcePaths](#2-optional-specify-the-location-of-the-engine-files) so that the SDK can correctly locate the resources.
-  > Since "node_modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node_modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-You can typically include SDK like this:
-
-```html
-<script src="path/to/dynamsoft-barcode-reader-bundle@10.4.3100/dist/dbr.bundle.js"></script>
-```
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-switching-end"></div>
-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the guides for [apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings) / [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap) / [nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types).
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Step 2: Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### 1. Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=10.4.31&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### 2. [Optional] Specify the location of the "engine" files
-
-This is usually only required with frameworks like Angular, React or Vue.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.).
-
-```ts
-// in framework
-import { CoreModule } from "dynamsoft-barcode-reader-bundle";
-CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-```js
-// in pure js
-Dynamsoft.Core.CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-These code uses the jsDelivr CDN as an example, feel free to change it to your own location.
-
-## Using the SDK
-
-### Step 1: Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm(["dbr"]);
-```
-
-### Step 2: Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pCvRouter` in the following code:
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let pCvRouter = null; // The helper variable which is a promise of cvRouter
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (pCvRouter = pCvRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-### Step 3: Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-### Step 4: Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. This time we use `onCapturedResultReceived`:
-<!--In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:-->
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onCapturedResultReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onCapturedResultReceived: (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/captured-result-receiver.html) for more information.
-
-### Step 5: Start process video frames
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans multiple barcodes by default setting.                    |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-Read more on the [preset CaptureVisionTemplates](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/preset-templates.html).
-
-## Customizing the process
-
-### 1. Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-#### 1.1. Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds =
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html) and [EnumBarcodeFormat](https://www.dynamsoft.com/capture-vision/docs/core/enums/barcode-reader/barcode-format.html?lang=js&product=dbr).
-
-#### 1.2. Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes |= 
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.capturedResultItemTypes = 
-  Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE |
-  Dynamsoft.Core.EnumCapturedResultItemType.CRIT_ORIGINAL_IMAGE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-const EnumCRIT = Dynamsoft.Core.EnumCapturedResultItemType;
-resultReceiver.onCapturedResultReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    // Use a filter to get the image on which barcodes are found.
-    let image = result.items.filter(
-      item => item.type === EnumCRIT.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-  }
-};
-```
-
-#### 1.3. Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-#### 1.4. Specify a scan region
-
-We can specify a scan region to allow the SDK to process only part of the image, improving processing speed. The code snippet below demonstrates how to do this using the `cameraEnhancer` image source.
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-// In this example, we set the scan region to cover the central 25% of the image.
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-*Note*:
-
-1. By configuring the region at the image source, images are cropped before processing, removing the need to adjust any further processing settings.
-2. `cameraEnhancer` enhances interactivity by overlaying a mask on the video, clearly marking the scanning region.
-
-*See Also*:
-
-[CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-<!-- Since DCE is always used, no need to use this approach
-
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-``` -->
-
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-### 2. Edit the preset templates directly
-
-The preset templates have many more settings that can be customized to suit your use case best. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-10.4.3100/dynamsoft/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); // E.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the template JSON file.
-```
-
-### 3. [Important] Filter the results
-
-When processing video frames, the same barcode is often detected multiple times. To improve the user experience, we can use the [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object. This object provides two methods for handling duplicate detections, which can be used independently or together, depending on what best suits your application needs:
-
-#### Method 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-#### Method 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.2.10 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime(5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-filter.enableResultDeduplication("barcode", true);
-filter.setDuplicateForgetTime(5000);
-await cvRouter.addResultFilter(filter);
-```
-
-### 4. Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-## Customizing the UI
-
-```javascript
-// Create a CameraView instance with default settings
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-// Create a CameraView instance with a specified HTML file path, typically a local or remote URL
-let cameraView1 = await Dynamsoft.DCE.CameraView.createInstance('@engineResourcePath/dce.mobile-native.ui.html');
-// Create a CameraView instance within a specified DOM element
-let cameraView2 = await Dynamsoft.DCE.CameraView.createInstance(document.getElementById('my-ui'));
-// Create a CameraView instance using a custom UI file path
-let cameraView3 = await Dynamsoft.DCE.CameraView.createInstance('url/to/my/ui.html');
-
-// Get the UI element associated with the cameraView instance
-let uiElement = cameraView.getUIElement();
-// Remove the camera selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-camera').remove();
-// Remove the resolution selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-resolution').remove();
-```
-
-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/ui-customization-js.html?lang=js).
-
-## Documentation
-
-### API Reference
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.4.3100](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=10.4.3100).
-
-<!--  Compatibility is basically not an issue. Pls remove to another place
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |

-
-**Basic Requirements**
-
-  - Internet connection
-  - A supported browser
-  - Camera access
-
-> Please refer to [system requirements](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/faq/system-requirement.html) for more details.

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#1-specify-the-license).
-
-- `Dynamsoft.Core.CoreModule.loadWasm()`: This is an optional code. Used to load wasm resources in advance, reducing latency between video playing and barcode decoding.
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#step-4-register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#3-important-filter-the-results) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```
-

-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=11.0.30&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/csm2f9wb/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.
-
-> *Secure Contexts*:
->
-> If you open the web page as `http://` , our SDK may not work correctly because the [MediaDevices: getUserMedia()](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) and other methods only work in [secure contexts](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts) (HTTPS, `localhost`, `127.0.0.1`, `file://`), in some or all supporting browsers.
->
-> Regarding configuring https on your server, these guides for [nginx](https://nginx.org/en/docs/http/configuring_https_servers.html) / [IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/) / [tomcat](https://dzone.com/articles/setting-ssl-tomcat-5-minutes) / [nodejs](https://nodejs.org/docs/v0.4.1/api/tls.html) might help.

-
-## Preparing the SDK
-
-### Step 1: Include the SDK
-
-<div class="multi-panel-switching-prefix"></div>
-<!-- 
-- [Use a public CDN](#useapubliccdn)
-- [Host the SDK yourself](#hostthesdkyourself) -->
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Use a public CDN</div>
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-  ```
-
-<!-- - In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-  ```html
-  <script src="https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-  ```
-
-  However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself. -->
-
-- In frameworks like React, Vue and Angular, you may want to add the package as a dependency.
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.3000 -E
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@11.0.3000 -E
-  ```
-
-  NOTE that in frameworks, you need to [specify the location of the engine files](#2-optional-specify-the-location-of-the-engine-files).
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Host the SDK yourself</div>
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=11.0.30&utm_source=guide&product=dbr&package=js)
-
-  The resources are located at path `dynamsoft/distributables/<pkg>@<version>`.
-
-- From npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.3000 -E
-  # Compared with using CDN, you need to set up more resources.
-  npm i dynamsoft-capture-vision-std@1.4.21 -E
-  npm i dynamsoft-image-processing@2.4.31 -E
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You must copy "dynamsoft-xxx" packages elsewhere and add `@<version>`. The `<version>` can be obtained from `package.json` of each package. Another thing to do is to [specify the engineResourcePaths](#2-optional-specify-the-location-of-the-engine-files) so that the SDK can correctly locate the resources.
-  > Since "node_modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node_modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-You can typically include SDK like this:
-
-```html
-<script src="path/to/dynamsoft-barcode-reader-bundle@11.0.3000/dist/dbr.bundle.js"></script>
-```
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-switching-end"></div>
-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the guides for [apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings) / [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap) / [nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types).
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Step 2: Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### 1. Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=11.0.30&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### 2. [Optional] Specify the location of the "engine" files
-
-This step is generally necessary when utilizing frameworks such as Angular, React, Vue, or when managing the hosting of resource files yourself.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.).
-
-```ts
-// in framework
-import { CoreModule } from "dynamsoft-barcode-reader-bundle";
-CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-```js
-// in pure js
-Dynamsoft.Core.CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-These code uses the jsDelivr CDN as an example, feel free to change it to your own location.
-
-## Using the SDK
-
-### Step 1: Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm();
-```
-
-### Step 2: Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pCvRouter` in the following code:
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let pCvRouter = null; // The helper variable which is a promise of cvRouter
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (pCvRouter = pCvRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-### Step 3: Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-### Step 4: Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. This time we use `onCapturedResultReceived`:
-<!--In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:-->
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onCapturedResultReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onCapturedResultReceived: (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/captured-result-receiver.html) for more information.
-
-### Step 5: Start process video frames
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans multiple barcodes by default setting.                    |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-Read more on the [preset CaptureVisionTemplates](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/preset-templates.html).
-
-## Customizing the process
-
-### 1. Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-#### 1.1. Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html) and [EnumBarcodeFormat](https://www.dynamsoft.com/capture-vision/docs/core/enums/barcode-reader/barcode-format.html?lang=js&product=dbr).
-
-#### 1.2. Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.outputOriginalImage = true;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.outputOriginalImage = true;
-settings.barcodeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-const EnumCRIT = Dynamsoft.Core.EnumCapturedResultItemType;
-resultReceiver.onCapturedResultReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    // Use a filter to get the image on which barcodes are found.
-    let image = result.items.filter(
-      item => item.type === EnumCRIT.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-  }
-};
-```
-
-#### 1.3. Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-#### 1.4. Specify a scan region
-
-We can specify a scan region to allow the SDK to process only part of the image, improving processing speed. The code snippet below demonstrates how to do this using the `cameraEnhancer` image source.
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-// In this example, we set the scan region to cover the central 25% of the image.
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-*Note*:
-
-1. By configuring the region at the image source, images are cropped before processing, removing the need to adjust any further processing settings.
-2. `cameraEnhancer` enhances interactivity by overlaying a mask on the video, clearly marking the scanning region.
-
-*See Also*:
-
-[CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-<!-- Since DCE is always used, no need to use this approach
-
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-``` -->
-
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-### 2. Edit the preset templates directly
-
-The preset templates have many more settings that can be customized to suit your use case best. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-11.0.3000/dynamsoft/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); // E.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the template JSON file.
-```
-
-### 3. [Important] Filter the results
-
-When processing video frames, the same barcode is often detected multiple times. To improve the user experience, we can use the [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object. This object provides two methods for handling duplicate detections, which can be used independently or together, depending on what best suits your application needs:
-
-#### Method 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-#### Method 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.2.10 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime("barcode", 5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-filter.enableResultDeduplication("barcode", true);
-filter.setDuplicateForgetTime("barcode", 5000);
-await cvRouter.addResultFilter(filter);
-```
-
-### 4. Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-## Customizing the UI
-
-```javascript
-// Create a CameraView instance with default settings
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-// Create a CameraView instance with a specified HTML file path, typically a local or remote URL
-let cameraView1 = await Dynamsoft.DCE.CameraView.createInstance('@engineResourcePath/dce.mobile-native.ui.html');
-// Create a CameraView instance within a specified DOM element
-let cameraView2 = await Dynamsoft.DCE.CameraView.createInstance(document.getElementById('my-ui'));
-// Create a CameraView instance using a custom UI file path
-let cameraView3 = await Dynamsoft.DCE.CameraView.createInstance('url/to/my/ui.html');
-
-// Get the UI element associated with the cameraView instance
-let uiElement = cameraView.getUIElement();
-// Remove the camera selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-camera').remove();
-// Remove the resolution selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-resolution').remove();
-```
-
-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/ui-customization-js.html?lang=js).

-## Documentation
-
-### API Reference
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=11.0.3000](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=11.0.3000).
-
-<!--  Compatibility is basically not an issue. Pls remove to another place
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |
-  | :----------: | :--------------: |
-  |    Chrome    | v78+<sup>1</sup> |
-  |   Firefox    | v68+<sup>1</sup> |
-  |     Edge     |       v79+       |
-  |    Safari    |       v14+       |
-
-  <sup>1</sup> devices running iOS needs to be on iOS 14.3+ for camera video streaming to work in Chrome, Firefox or other Apps using webviews.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.

-## Hello World - Simplest Implementation
-
-Let's start with the "Hello World" example of the DBR-JS SDK which demonstrates how to use the minimum code to enable a web page to read barcodes from a live video stream.  
-
-**Basic Requirements**
-
-  - Internet connection
-  - A supported browser
-  - Camera access
-
-> Please refer to [system requirements](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/faq/system-requirement.html) for more details.

-#### About the code
-
-- `Dynamsoft.License.LicenseManager.initLicense()`: This method initializes the license for using the SDK in the application. Note that the string "**DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9**" used in this example points to an online license that requires a network connection to work. Read more on [Specify the license](#1-specify-the-license).
-
-- `Dynamsoft.Core.CoreModule.loadWasm()`: This is an optional code. Used to load wasm resources in advance, reducing latency between video playing and barcode decoding.
-
-- `Dynamsoft.CVR.CaptureVisionRouter.createInstance()`: This method creates a `CaptureVisionRouter` object `cvRouter` which controls the entire process in three steps:
-  - **Retrieve Images from the Image Source**
-    - `cvRouter` connects to the image source through the [ImageSourceAdapter](https://www.dynamsoft.com/capture-vision/docs/core/architecture/input.html#image-source-adapter?lang=js) interface with the method `setInput()`.
-      ```js
-      cvRouter.setInput(cameraEnhancer);
-      ```
-    > The image source in our case is a [CameraEnhancer](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/user-guide/index.html) object created with `Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView)`
-  - **Coordinate Image-Processing Tasks**
-    - The coordination happens behind the scenes. `cvRouter` starts the process by specifying a preset template "ReadSingleBarcode" in the method `startCapturing()`.
-      ```js
-      cvRouter.startCapturing("ReadSingleBarcode");
-      ```
-  - **Dispatch Results to Listening Objects**
-    - The processing results are returned through the [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/core/architecture/output.html#captured-result-receiver?lang=js) interface. The `CapturedResultReceiver` object is registered to `cvRouter` via the method `addResultReceiver()`. For more information, please check out [Register a result receiver](#step-4-register-a-result-receiver).
-      ```js
-      cvRouter.addResultReceiver({/*The-CapturedResultReceiver-Object"*/});
-      ```
-    - Also note that reading from video is extremely fast and there could be many duplicate results. We can use a [filter](#3-important-filter-the-results) with result deduplication enabled to filter out the duplicate results. The object is registered to `cvRouter` via the method `addResultFilter()`.
-      ```js
-      cvRouter.addResultFilter(filter);
-      ```
-

-
-### Run the example
-
-You can run the example deployed to [the Dynamsoft Demo Server](https://demo.dynamsoft.com/Samples/DBR/JS/hello-world/hello-world.html?ver=11.0.60&utm_source=guide) or test it with [JSFiddle code editor](https://jsfiddle.net/DynamsoftTeam/csm2f9wb/). 
-
-You will be asked to allow access to your camera, after which the video will be displayed on the page. After that, you can point the camera at a barcode to read it.
-
-When a barcode is decoded, you will see the result text show up under the video and the barcode location will be highlighted in the video feed.
-
-Alternatively, you can test locally by copying and pasting the code shown above into a local file (e.g. "hello-world.html") and opening it in your browser.
-
-> *Secure Contexts*:
->
-> If you open the web page as `http://` , our SDK may not work correctly because the [MediaDevices: getUserMedia()](https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) and other methods only work in [secure contexts](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts) (HTTPS, `localhost`, `127.0.0.1`, `file://`), in some or all supporting browsers.
->
-> Regarding configuring https on your server, these guides for [nginx](https://nginx.org/en/docs/http/configuring_https_servers.html) / [IIS](https://aboutssl.org/how-to-create-a-self-signed-certificate-in-iis/) / [tomcat](https://dzone.com/articles/setting-ssl-tomcat-5-minutes) / [nodejs](https://nodejs.org/docs/v0.4.1/api/tls.html) might help.

-## Preparing the SDK
-
-### Step 1: Include the SDK
-
-<div class="multi-panel-switching-prefix"></div>
-<!-- 
-- [Use a public CDN](#useapubliccdn)
-- [Host the SDK yourself](#hostthesdkyourself) -->
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Use a public CDN</div>
-
-The simplest way to include the SDK is to use either the [jsDelivr](https://jsdelivr.com/) or [UNPKG](https://unpkg.com/) CDN. The "hello world" example above uses **jsDelivr**.
-
-- jsDelivr
-
-  ```html
-  <script src="https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-  ```
-
-- UNPKG
-
-  ```html
-  <script src="https://unpkg.com/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-  ```
-
-<!-- - In some rare cases (such as some restricted areas), you might not be able to access the CDN. If this happens, you can use the following files for the test.
-
-  ```html
-  <script src="https://download2.dynamsoft.com/packages/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-  ```
-
-  However, please **DO NOT** use `download2.dynamsoft.com` resources in a production application as they are for temporary testing purposes only. Instead, you can try hosting the SDK yourself. -->
-
-- In frameworks like React, Vue and Angular, you may want to add the package as a dependency.
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.6000 -E
-  # or
-  yarn add dynamsoft-barcode-reader-bundle@11.0.6000 -E
-  ```
-
-  NOTE that in frameworks, you need to [specify the location of the engine files](#2-optional-specify-the-location-of-the-engine-files).
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-start"></div>
-<div class="multi-panel-title">Host the SDK yourself</div>
-
-Besides using the public CDN, you can also download the SDK and host its files on your own server or a commercial CDN before including it in your application.
-
-- From the website
-
-  [Download Dynamsoft Barcode Reader JavaScript Package](https://www.dynamsoft.com/barcode-reader/downloads/?ver=11.0.60&utm_source=guide&product=dbr&package=js)
-
-  The resources are located at path `dynamsoft/distributables/<pkg>@<version>`.
-
-- From npm
-
-  ```sh
-  npm i dynamsoft-barcode-reader-bundle@11.0.6000 -E
-  # Compared with using CDN, you need to set up more resources.
-  npm i dynamsoft-capture-vision-std@1.4.21 -E
-  npm i dynamsoft-image-processing@2.4.31 -E
-  ```
-
-  The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You must copy "dynamsoft-xxx" packages elsewhere and add `@<version>`. The `<version>` can be obtained from `package.json` of each package. Another thing to do is to [specify the engineResourcePaths](#2-optional-specify-the-location-of-the-engine-files) so that the SDK can correctly locate the resources.
-  > Since "node_modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node_modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-You can typically include SDK like this:
-
-```html
-<script src="path/to/dynamsoft-barcode-reader-bundle@11.0.6000/dist/dbr.bundle.js"></script>
-```
-<div class="multi-panel-end"></div>
-
-<div class="multi-panel-switching-end"></div>
-
-*Note*:
-
-* Certain legacy web application servers may lack support for the `application/wasm` mimetype for .wasm files. To address this, you have two options:
-  1. Upgrade your web application server to one that supports the `application/wasm` mimetype.
-  2. Manually define the mimetype on your server. You can refer to the guides for [apache](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Apache_Configuration_htaccess#media_types_and_character_encodings) / [IIS](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/staticcontent/mimemap) / [nginx](https://www.nginx.com/resources/wiki/start/topics/examples/full/#mime-types).
-
-* To work properly, the SDK requires a few engine files, which are relatively large and may take quite a few seconds to download. We recommend that you set a longer cache time for these engine files, to maximize the performance of your web application.
-
-  ```
-  Cache-Control: max-age=31536000
-  ```
-
-  Reference: [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control).
-
-### Step 2: Prepare the SDK
-
-Before using the SDK, you need to configure a few things.
-
-#### 1. Specify the license
-
-To enable the SDK's functionality, you must provide a valid license. Utilize the API function initLicense to set your license key.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-```
-
-As previously stated, the key "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9" serves as a test license valid for 24 hours, applicable to any newly authorized browser. To test the SDK further, you can request a 30-day free trial license via the <a href="https://www.dynamsoft.com/customer/license/trialLicense?ver=11.0.60&utm_source=guide&product=dbr&package=js" target="_blank">Request a Trial License</a> link.
-
-> Upon registering a Dynamsoft account and obtaining the SDK package from the official website, Dynamsoft will automatically create a 30-day free trial license and embed the corresponding license key into all the provided SDK samples.
-
-#### 2. [Optional] Specify the location of the "engine" files
-
-This step is generally necessary when utilizing frameworks such as Angular, React, Vue, or when managing the hosting of resource files yourself.
-
-The purpose is to tell the SDK where to find the engine files (\*.worker.js, \*.wasm.js and \*.wasm, etc.).
-
-```ts
-// in framework
-import { CoreModule } from "dynamsoft-barcode-reader-bundle";
-CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-```js
-// in pure js
-Dynamsoft.Core.CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-```
-These code uses the jsDelivr CDN as an example, feel free to change it to your own location.
-
-## Using the SDK
-
-### Step 1: Preload the module
-
-The image processing logic is encapsulated within .wasm library files, and these files may require some time for downloading. To enhance the speed, we advise utilizing the following method to preload the libraries.
-
-```js
-// Preload the .wasm files
-await Dynamsoft.Core.CoreModule.loadWasm();
-```
-
-### Step 2: Create a CaptureVisionRouter object
-
-To use the SDK, we first create a `CaptureVisionRouter` object.
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let cvRouter = null;
-try {
-    cvRouter = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
-} catch (ex) {
-    console.error(ex);
-}
-```
-
-*Tip*:
-
-When creating a `CaptureVisionRouter` object within a function which may be called more than once, it's best to use a "helper" variable to avoid double creation such as `pCvRouter` in the following code:
-
-```javascript
-Dynamsoft.License.LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-let pCvRouter = null; // The helper variable which is a promise of cvRouter
-let cvRouter = null;
-
-document.getElementById('btn-scan').addEventListener('click', async () => {
-    try {
-        cvRouter = await (pCvRouter = pCvRouter || Dynamsoft.CVR.CaptureVisionRouter.createInstance());
-    } catch (ex) {
-        console.error(ex);
-    }
-});
-```
-
-### Step 3: Connect an image source
-
-The `CaptureVisionRouter` object, denoted as `cvRouter`, is responsible for handling images provided by an image source. In our scenario, we aim to detect barcodes directly from a live video stream. To facilitate this, we initialize a `CameraEnhancer` object, identified as `cameraEnhancer`, which is specifically designed to capture image frames from the video feed and subsequently forward them to `cvRouter`.
-
-To enable video streaming on the webpage, we create a `CameraView` object referred to as `cameraView`, which is then passed to `cameraEnhancer`, and its content is displayed on the webpage.
-
-```html
-<div id="camera-view-container" style="width: 100%; height: 100vh"></div>
-```
-
-```javascript
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-let cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-document.querySelector("#camera-view-container").append(cameraView.getUIElement());
-cvRouter.setInput(cameraEnhancer);
-```
-
-### Step 4: Register a result receiver
-
-Once the image processing is complete, the results are sent to all the registered `CapturedResultReceiver` objects. Each `CapturedResultReceiver` object may encompass one or multiple callback functions associated with various result types. This time we use `onDecodedBarcodesReceived`:
-<!--In our particular case, our focus is on identifying barcodes within the images, so it's sufficient to define the callback function `onDecodedBarcodesReceived`:-->
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived  = (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-You can also write code like this. It is the same.
-
-```javascript
-const resultsContainer = document.querySelector("#results");
-cvRouter.addResultReceiver({ onDecodedBarcodesReceived: (result) => {
-  if (result.barcodeResultItems?.length) {
-    resultsContainer.textContent = '';
-    for (let item of result.barcodeResultItems) {
-      // In this example, the barcode results are displayed on the page below the video.
-      resultsContainer.textContent += `${item.formatString}: ${item.text}\n\n`;
-    }
-  }
-}});
-```
-
-Check out [CapturedResultReceiver](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/captured-result-receiver.html) for more information.
-
-### Step 5: Start process video frames
-
-With the setup now complete, we can proceed to process the images in two straightforward steps:
-
-1. Initiate the image source to commence image acquisition. In our scenario, we invoke the `open()` method on `cameraEnhancer` to initiate video streaming and simultaneously initiate the collection of images. These collected images will be dispatched to `cvRouter` as per its request.
-2. Define a preset template to commence image processing. In our case, we utilize the "ReadSingleBarcode" template, specifically tailored for processing images containing a single barcode.
-
-```javascript
-await cameraEnhancer.open();
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-*Note*:
-
-* `cvRouter` is engineered to consistently request images from the image source.
-* Various preset templates are at your disposal for barcode reading:
-
-| Template Name                  | Function Description                                           |
-| ------------------------------ | -------------------------------------------------------------- |
-| **ReadBarcodes_Default**       | Scans multiple barcodes by default setting.                    |
-| **ReadSingleBarcode**          | Quickly scans a single barcode.                                |
-| **ReadBarcodes_SpeedFirst**    | Prioritizes speed in scanning multiple barcodes.               |
-| **ReadBarcodes_ReadRateFirst** | Maximizes the number of barcodes read.                         |
-| **ReadBarcodes_Balance**       | Balances speed and quantity in reading multiple barcodes.      |
-| **ReadDenseBarcodes**          | Specialized in reading barcodes with high information density. |
-| **ReadDistantBarcodes**        | Capable of reading barcodes from extended distances.           |
-
-Read more on the [preset CaptureVisionTemplates](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/preset-templates.html).
-
-## Customizing the process
-
-### 1. Adjust the preset template settings
-
-When making adjustments to some basic tasks, we often only need to modify [SimplifiedCaptureVisionSettings](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/interfaces/simplified-capture-vision-settings.html).
-
-#### 1.1. Change barcode settings
-
-The preset templates can be updated to meet different requirements. For example, the following code limits the barcode format to QR code.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.barcodeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-For a list of adjustable barcode settings, check out [SimplifiedBarcodeReaderSettings](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/interfaces/simplified-barcode-reader-settings.html) and [EnumBarcodeFormat](https://www.dynamsoft.com/capture-vision/docs/core/enums/barcode-reader/barcode-format.html?lang=js&product=dbr).
-
-#### 1.2. Retrieve the original image
-
-Additionally, we have the option to modify the template to retrieve the original image containing the barcode.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.outputOriginalImage = true;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Limit the barcode format to QR code, and retrieve the original image containing the barcode, at the same time.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.outputOriginalImage = true;
-settings.barcodeSettings.barcodeFormatIds = Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-Please be aware that it is necessary to update the `CapturedResultReceiver` object to obtain the original image. For instance:
-
-```javascript
-const EnumCRIT = Dynamsoft.Core.EnumCapturedResultItemType;
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems?.length) {
-    // Use a filter to get the image on which barcodes are found.
-    let image = result.items.filter(
-      item => item.type === EnumCRIT.CRIT_ORIGINAL_IMAGE
-    )[0].imageData;
-  }
-};
-```
-
-#### 1.3. Change reading frequency to save power
-
-The SDK is initially configured to process images sequentially without any breaks. Although this setup maximizes performance, it can lead to elevated power consumption, potentially causing the device to overheat. In many cases, it's possible to reduce the reading speed while still satisfying business requirements. The following code snippet illustrates how to adjust the SDK to process an image every 500 milliseconds:
-
-> Please bear in mind that in the following code, if an image's processing time is shorter than 500 milliseconds, the SDK will wait for the full 500 milliseconds before proceeding to process the next image. Conversely, if an image's processing time exceeds 500 milliseconds, the subsequent image will be processed immediately upon completion.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.minImageCaptureInterval = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
-
-#### 1.4. Specify a scan region
-
-We can specify a scan region to allow the SDK to process only part of the image, improving processing speed. The code snippet below demonstrates how to do this using the `cameraEnhancer` image source.
-
-```javascript
-cameraEnhancer = await Dynamsoft.DCE.CameraEnhancer.createInstance(cameraView);
-// In this example, we set the scan region to cover the central 25% of the image.
-cameraEnhancer.setScanRegion({
-  x: 25,
-  y: 25,
-  width: 50,
-  height: 50,
-  isMeasuredInPercentage: true,
-});
-```
-
-*Note*:
-
-1. By configuring the region at the image source, images are cropped before processing, removing the need to adjust any further processing settings.
-2. `cameraEnhancer` enhances interactivity by overlaying a mask on the video, clearly marking the scanning region.
-
-*See Also*:
-
-[CameraEnhancer::setScanRegion](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#setscanregion)
-
-<!-- Since DCE is always used, no need to use this approach
-
-
-You can use the parameter `roi` (region of interest) together with the parameter `roiMeasuredInPercentage` to configure the SDK to only read a specific region on the image frames. For example, the following code limits the reading in the center 25%( = 50% * 50%) of the image frames:
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.roiMeasuredInPercentage = true;
-settings.roi.points = [
-  { x: 25, y: 25 },
-  { x: 75, y: 25 },
-  { x: 75, y: 75 },
-  { x: 25, y: 75 },
-];
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-``` -->
-
-
-<!--
-* Specify the maximum time allowed for processing each image
-
-You can set the maximum time allowed for processing a single image with the property `timeout`.
-
-> Please be aware that the SDK will cease processing an image if its processing time exceeds the duration specified by the `timeout` parameter. It should not be confused with the previously discussed parameter, `minImageCaptureInterval`.
-
-```javascript
-let settings = await cvRouter.getSimplifiedSettings("ReadSingleBarcode");
-settings.timeout = 500;
-await cvRouter.updateSettings("ReadSingleBarcode", settings);
-await cvRouter.startCapturing("ReadSingleBarcode");
-```
--->
-
-### 2. Edit the preset templates directly
-
-The preset templates have many more settings that can be customized to suit your use case best. If you [download the SDK from Dynamsoft website](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/), you can find the templates under
-
-* "/dynamsoft-barcode-reader-js-11.0.6000/dynamsoft/templates/"
-
-Upon completing the template editing, you can invoke the `initSettings` method and provide it with the template path as an argument.
-
-```javascript
-await cvRouter.initSettings("PATH-TO-THE-FILE"); // E.g. "https://your-website/ReadSingleBarcode.json")
-await cvRouter.startCapturing("ReadSingleBarcode"); // Make sure the name matches one of the CaptureVisionTemplates in the template JSON file.
-```
-
-### 3. [Important] Filter the results
-
-When processing video frames, the same barcode is often detected multiple times. To improve the user experience, we can use the [MultiFrameResultCrossFilter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/utility/multi-frame-result-cross-filter.html) object. This object provides two methods for handling duplicate detections, which can be used independently or together, depending on what best suits your application needs:
-
-#### Method 1: Verify results across multiple frames
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultCrossVerification` was designed to cross-validate the outcomes across various frames in a video streaming scenario, enhancing the reliability of the final results. This validation is particularly crucial for barcodes with limited error correction capabilities, such as 1D codes.
-
-#### Method 2: Eliminate redundant results detected within a short time frame
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultDeduplication("barcode", true);
-await cvRouter.addResultFilter(filter);
-```
-
-*Note*:
-
-* `enableResultDeduplication` was designed to prevent high usage in video streaming scenarios, addressing the repetitive processing of the same code within a short period of time.
-
-Initially, the filter is set to forget a result 3 seconds after it is first received. During this time frame, if an identical result appears, it is ignored.
-
-> It's important to know that in version 9.x or earlier, the occurrence of an identical result would reset the timer, thus reinitiating the 3-second count at that point. However, in version 10.2.10 and later, an identical result no longer resets the timer but is instead disregarded, and the duration count continues uninterrupted.
-
-Under certain circumstances, this duration can be extended with the method `setDuplicateForgetTime()`.
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.setDuplicateForgetTime("barcode", 5000); // Extend the duration to 5 seconds.
-await cvRouter.addResultFilter(filter);
-```
-
-You can also enable both options at the same time:
-
-```js
-let filter = new Dynamsoft.Utility.MultiFrameResultCrossFilter();
-filter.enableResultCrossVerification("barcode", true);
-filter.enableResultDeduplication("barcode", true);
-filter.setDuplicateForgetTime("barcode", 5000);
-await cvRouter.addResultFilter(filter);
-```
-
-### 4. Add feedback
-
-When a barcode is detected within the video stream, its position is immediately displayed within the video. Furthermore, utilizing the "Dynamsoft Camera Enhancer" SDK, we can introduce feedback mechanisms, such as emitting a "beep" sound or triggering a "vibration".
-
-The following code snippet adds a "beep" sound for when a barcode is found:
-
-```js
-const resultReceiver = new Dynamsoft.CVR.CapturedResultReceiver();
-resultReceiver.onDecodedBarcodesReceived = (result) => {
-  if (result.barcodeResultItems.length > 0) {
-    Dynamsoft.DCE.Feedback.beep();
-  }
-};
-cvRouter.addResultReceiver(resultReceiver);
-```
-
-## Customizing the UI
-
-```javascript
-// Create a CameraView instance with default settings
-let cameraView = await Dynamsoft.DCE.CameraView.createInstance();
-// Create a CameraView instance with a specified HTML file path, typically a local or remote URL
-let cameraView1 = await Dynamsoft.DCE.CameraView.createInstance('@engineResourcePath/dce.mobile-native.ui.html');
-// Create a CameraView instance within a specified DOM element
-let cameraView2 = await Dynamsoft.DCE.CameraView.createInstance(document.getElementById('my-ui'));
-// Create a CameraView instance using a custom UI file path
-let cameraView3 = await Dynamsoft.DCE.CameraView.createInstance('url/to/my/ui.html');
-
-// Get the UI element associated with the cameraView instance
-let uiElement = cameraView.getUIElement();
-// Remove the camera selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-camera').remove();
-// Remove the resolution selection dropdown from the CameraView's UI element
-uiElement.shadowRoot.querySelector('.dce-sel-resolution').remove();
-```
-
-The UI is part of the auxiliary SDK "Dynamsoft Camera Enhancer", read more on how to [customize the UI](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/ui-customization-js.html?lang=js).

-## Documentation
-
-### API Reference
-
-You can check out the detailed documentation about the APIs of the SDK at
-[https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=11.0.6000](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/?ver=11.0.6000).
-
-<!--  Compatibility is basically not an issue. Pls remove to another place
-
-## System Requirements
-
-DBR requires the following features to work:
-
-- Secure context (HTTPS deployment)
-
-  When deploying your application / website for production, make sure to serve it via a secure HTTPS connection. This is required for two reasons
-  
-  - Access to the camera video stream is only granted in a security context. Most browsers impose this restriction.
-  > Some browsers like Chrome may grant the access for `http://127.0.0.1` and `http://localhost` or even for pages opened directly from the local disk (`file:///...`). This can be helpful for temporary development and test.
-  
-  - Dynamsoft License requires a secure context to work.
-
-- `WebAssembly`, `Blob`, `URL`/`createObjectURL`, `Web Workers`
-
-  The above four features are required for the SDK to work.
-
-- `MediaDevices`/`getUserMedia`
-
-  This API is required for in-browser video streaming.
-
-- `getSettings`
-
-  This API inspects the video input which is a `MediaStreamTrack` object about its constrainable properties.
-
-The following table is a list of supported browsers based on the above requirements:
-
-  | Browser Name |     Version      |
-  | :----------: | :--------------: |
-  |    Chrome    | v78+<sup>1</sup> |
-  |   Firefox    | v68+<sup>1</sup> |
-  |     Edge     |       v79+       |
-  |    Safari    |       v14+       |
-
-  <sup>1</sup> devices running iOS needs to be on iOS 14.3+ for camera video streaming to work in Chrome, Firefox or other Apps using webviews.
-
-Apart from the browsers, the operating systems may impose some limitations of their own that could restrict the use of the SDK. Browser compatibility ultimately depends on whether the browser on that particular operating system supports the features listed above.

-# Use in Framework - User Guide
-
-Integrating [Dynamsoft Barcode Reader JavaScript Edition](https://www.dynamsoft.com/barcode-reader/sdk-javascript/) (DBR-JS) into frameworks like Angular, React, and Vue is a little different compared to native usage. This guide will quickly explain the common practices of integrating DBR-JS into these frameworks.
-
-You can also refer to [the ready-made samples for popular frameworks](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/hello-world) directly without reading this guide.
-
-## Installation
-
-Assuming you have an existing project using a framework, you should have a `package.json` file in your project's root directory.
-
-1. Open the terminal from your project root directory.
-2. Install DBR-JS SDK with the following command:
-
-```sh
-npm install dynamsoft-barcode-reader-bundle@10.2.1000 -E
-```
-
-3. Confirm the installation by checking the `package.json`. You should see:
-
-```json
-{
-  ...
-  "dependencies": {
-    ...
-    "dynamsoft-barcode-reader-bundle": "10.2.1000"
-  }
-}
-```
-
-Notice that there is no `^` before `10.2.1000`. No `^` indicates an exact version, ensuring stability and avoids automatic upgrades even without `package-lock.json`.
-
-While we keep the SDK's external interface relatively stable, the SDK's internal communication often change with each new version. These changes can potentially lead to compatibility issues with `engineResourcePaths` settings. To prevent any unexpected difficulties and surprises, it's essential to use the exact version of the SDK.
-
-## Configuration
-
-Next, we'll create a Configuration file for the common settings related to DBR-JS. If you use TypeScript, we can name the file `dynamsoft.config.ts`. This file is not a component, so you can place it under the `lib` directory or the root directory of `src`.
-
-```ts
-import { CoreModule } from "dynamsoft-core";
-import { LicenseManager } from "dynamsoft-license";
-import "dynamsoft-barcode-reader";
-
-// Configures the paths where the .wasm files and other necessary resources for modules are located.
-CoreModule.engineResourcePaths = {
-  std: "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-std@1.2.10/dist/",
-  dip: "https://cdn.jsdelivr.net/npm/dynamsoft-image-processing@2.2.30/dist/",
-  core: "https://cdn.jsdelivr.net/npm/dynamsoft-core@3.2.30/dist/",
-  license: "https://cdn.jsdelivr.net/npm/dynamsoft-license@3.2.21/dist/",
-  cvr: "https://cdn.jsdelivr.net/npm/dynamsoft-capture-vision-router@2.2.30/dist/",
-  dbr: "https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader@10.2.10/dist/",
-  dce: "https://cdn.jsdelivr.net/npm/dynamsoft-camera-enhancer@4.0.3/dist/"
-};
-
-/** LICENSE ALERT - README

-
-// Optional. Preload "BarcodeReader" module for reading barcodes. It will save time on the initial decoding by skipping the module loading.
-CoreModule.loadWasm(["DBR"]);
-```
-
-In order for these settings to take effect, `dynamsoft.config.ts` must be imported before using the barcode reader. Import this file at the entry point of your application, such as in `main.ts` or the root component. If you import `dynamsoft.config.ts` within a specific subcomponent, you can achieve lazy loading, which can save bandwidth by only loading the barcode feature when needed.
-
-Next, we will demonstrate how to introduce `dynamsoft.config.ts` into a specific component. Don't skip the [Component for Reading Image](#Component-for-Reading-Image) section even if you only need video barcode decoding.
-
-## Component for Reading Image
-
-A component's lifecycle includes creation and destruction, making it difficult to ensure that a component won't be rebuilt. Since the [CaptureVisionRouter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html?product=dbr&lang=javascript#capturevisionrouter-class) object is associated with a [Worker](https://developer.mozilla.org/en-US/docs/Web/API/Worker), it cannot be automatically garbage collected. Therefore, we need to manually [dispose](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/instantiate.html?product=dbr&lang=javascript#dispose) of it.
-
-```ts
-import "../../dynamsoft.config";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cvRouter;
-
-// create cvRouter before it's needed
-// for example, after the component is mounted
-async mounted(){
-  cvRouter = await CaptureVisionRouter.createInstance();
-}
-
-// dispose cvRouter when it's no longer needed
-beforeUnmount(){
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-```
-
-In scenarios where users may click the button quickly, the component might be destroyed before `cvRouter` is fully created. To handle this situation, we'll need to implement some techniques to ensure proper resource management.
-
-Here's an improved version of the code to address this issue:
-
-```ts
-let pCvRouter; // promise of cvRouter
-
-// create cvRouter before it's needed
-// for example, after the component is mounted
-async mounted(){
-  cvRouter = await (pCvRouter = CaptureVisionRouter.createInstance());
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  await pCvRouter; // ensure cvrouter creation is complete
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-```
-
-### Reading Barcode from an Uploaded File
-
-In some cases, you might need to read barcode from an uploaded file. Here's how to handle that in your component.
-
-```tsx
-import { EnumCapturedResultItemType } from "dynamsoft-core";
-
-async function captureImage(e: Event){
-  // Some frameworks will wrap the event. Refer to DBRJS samples of each frameworks for details
-  let file = e.target.files[0];
-  e.target.value = ''; // reset input
-
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  for (let item of result.items) {
-    // check if captured result item is a barcode
-    if(item.type !== EnumCapturedResultItemType.CRIT_BARCODE) { 
-      continue; // Skip processing if the result is not a barcode
-    } 
-    console.log(item.text); // output the decoded barcode text
-  }
-}
-
-// usage example in a tsx/jsx component
-<input type="file" onChange={captureImage}>
-```
-
-### Lazy Loading `cvRouter`
-
-To optimize resource usage, you might want to lazy load `cvRouter` only after the client uploads a file.
-
-```ts
-async captureImage(e: Event){
-  // ...
-  cvRouter = await (pCvRouter = CaptureVisionRouter.createInstance());
-  // ...
-}
-```
-
-Additionally, users may repeatedly upload files which can result in multiple instances being created, potentially causing memory leaks. Here's how we could handle this.
-
-```ts
-async captureImage(e: Event){
-  // ...
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  // ...
-}
-```
-
-### Handling Component Destruction During Decoding
-
-When decoding barcodes, it's common for users to switch to another component. If you're familiar with handling network requests, you know that this situation is very common.
-
-Here's how we could handle with proper checks to avoid program errors:
-
-```ts
-let isDestroyed = false;
-
-async captureImage(e: Event){
-  // ensure cvRouter is created only once
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-  // ...
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  if(isDestroyed){ return; }
-
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCvRouter;
-  cvRouter?.dispose();
-  cvRouter = null;
-}
-```
-
-By adding a check for `isDestroyed` after each `await`, we can ensure that the code handles the component's potential destruction properly, avoiding errors and resource leaks.
-
-### Complete Code Example
-
-```tsx
-import "../../dynamsoft.config";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cvRouter;
-let pCvRouter; // promise of cvRouter
-let isDestroyed = false;
-
-async captureImage(e: Event){
-  // Some frameworks will wrap the event. Refer to DBRJS samples of each frameworks for details
-  let file = e.target.files[0];
-  e.target.value = ''; // reset input
-
-  // ensure cvRouter is created only once
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  if(isDestroyed){ return; }
-
-  for (let item of result.items) {
-    // check if captured result item is a barcode
-    if(item.type !== EnumCapturedResultItemType.CRIT_BARCODE) { 
-      continue; // Skip processing if the result is not a barcode
-    } 
-    console.log(item.text); // output the decoded barcode text
-  }
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCvRouter; // ensure cvrouter creation is complete
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-
-// usage example in a tsx/jsx component
-<input type="file" onChange={captureImage}>
-```
-
-> If you find it difficult to think about these, don't worry, just go to [DBRJS samples for framework](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/hello-world), copy these components into your project.

-## Component for Decoding Video
-
-### Set up the video ([CameraView](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/cameraview.html)) container
-To render video within a component and handle its lifecycle properly, we can use framework's methods (such as `#` or `ref` or `bind:this`) to get the component's `HTMLDivElement`. This is where the video will be rendered.
-
-```tsx
-let cameraviewContainer;
-
-<div ref={cameraViewContainer}></div>
-```
-
-### Render the Video UI
-
-The [`CameraEnhancer`](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/index.html) instance needs to be properly created and [disposed](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/instantiate.html#dispose) of to manage resources.
-
-```ts
-import "../dynamsoft.config";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-
-let cameraEnhancer;
-let pCameraEnhancer; // promise of cameraEnhancer
-let isDestroyed = false;
-
-async mount(){
-  // create a `CameraEnhancer` instance for camera control and a `CameraView` instance for UI control.
-  const cameraView = await CameraView.createInstance();
-  if(isDestroyed){ return; } // Check if component is destroyed after every async
-
-  cameraEnhancer = await (pCameraEnhancer || CameraEnhancer.createInstance(cameraView));
-  if(isDestroyed){ return; }
-
-  // Get default UI and append it to DOM.
-  cameraViewContainer.append(cameraView.getUIElement());
-}
-
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCameraEnhancer;
-  cameraEnhancer?.dispose();
-  cameraEnhancer = null;
-}
-
-// usage example in a tsx/jsx component
-<div ref={cameraViewContainer}></div>
-```
-
-### Add [`CaptureVisionRouter`](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html)
-
-To complete the code, we'll include the [`CaptureVisionRouter`](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html) and handle it's life cycle similarly.
-
-```ts
-import "../dynamsoft.config";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cameraEnhancer;
-let pCameraEnhancer; // promise of cameraEnhancer
-let cvRouter;
-let pCvRouter; // promise of cvRouter
-let isDestroyed = false;
-
-async mount(){
-  // Create a `CameraEnhancer` instance for camera control and a `CameraView` instance for UI control.
-  const cameraView = await CameraView.createInstance();
-  if(isDestroyed){ return; } // Check if component is destroyed after every async
-  
-  cameraEnhancer = await (pCameraEnhancer || CameraEnhancer.createInstance(cameraView));
-  if(isDestroyed){ return; }
-
-  // Get default UI and append it to DOM.
-  cameraViewContainer.append(cameraView.getUIElement());
-

-### Final Notes
-
-Decoding video is slightly more complex than reading image, but by following the steps above, you can manage resources effectively and ensure your component runs smoothly.
-
-Again, if you don't want to go into detail, please refer to the [DBRJS sample](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/hello-world) directly.
-
-Note that since we have taken over native rendering, avoid changing the UI through the framework within decoding video component; instead, make changes in its parent component.
-
-Once this component is rendered, decoding will start. You can control when decoding occurs by not rendering this component until needed.

-# Use in Framework - User Guide
-
-Integrating [Dynamsoft Barcode Reader JavaScript Edition](https://www.dynamsoft.com/barcode-reader/sdk-javascript/) (DBR-JS) into frameworks like Angular, React, and Vue is a little different compared to native usage. This guide will quickly explain the common practices of integrating DBR-JS into these frameworks.
-
-You can also refer to [the ready-made samples for popular frameworks](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/hello-world) directly without reading this guide.
-
-## Installation
-
-Assuming you have an existing project using a framework, you should have a `package.json` file in your project's root directory.
-
-1. Open the terminal from your project root directory.
-2. Install DBR-JS SDK with the following command:
-
-    ```sh
-    npm install dynamsoft-barcode-reader-bundle@10.4.2002 -E
-    ```
-
-3. Confirm the installation by checking the `package.json`. You should see:
-
-    ```json
-    {
-      ...
-      "dependencies": {
-        ...
-        "dynamsoft-barcode-reader-bundle": "10.4.2002"
-      }
-    }
-    ```
-
-Notice that there is no `^` before `10.4.2002`. No `^` indicates an exact version, ensuring stability and avoids automatic upgrades even without `package-lock.json`.
-
-While we keep the SDK's external interface relatively stable, the SDK's internal communication often change with each new version. These changes can potentially lead to compatibility issues with `engineResourcePaths` settings. To prevent any unexpected difficulties and surprises, it's essential to use the exact version of the SDK.
-
-## Configuration
-
-Next, we'll create a Configuration file for the common settings related to DBR-JS. If you use TypeScript, we can name the file `dynamsoft.config.ts`. This file is not a component, so you can place it under the `lib` directory or the root directory of `src`.
-
-```ts
-import { CoreModule } from "dynamsoft-core";
-import { LicenseManager } from "dynamsoft-license";
-import "dynamsoft-barcode-reader";
-
-// Configures the root path where the .wasm files and other necessary resources for modules are located.
-CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-
-/** LICENSE ALERT - README
- * To use the library, you need to first specify a license key using the API "initLicense()" as shown below.
- */
-
-LicenseManager.initLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
-
-/**
- * You can visit https://www.dynamsoft.com/customer/license/trialLicense?utm_source=github&product=dbr&package=js to get your own trial license good for 30 days.
- * Note that if you downloaded this sample from Dynamsoft while logged in, the above license key may already be your own 30-day trial license.
- * For more information, see https://www.dynamsoft.com/barcode-reader/programming/javascript/user-guide/?ver=10.4.20&utm_source=github#specify-the-license or contact support@dynamsoft.com.
- * LICENSE ALERT - THE END
- */
-
-// Optional. Preload "BarcodeReader" module for reading barcodes. It will save time on the initial decoding by skipping the module loading.
-CoreModule.loadWasm(["DBR"]);
-```
-
-In order for these settings to take effect, `dynamsoft.config.ts` must be imported before using the barcode reader. One approach is to import this file at the entry point of the application, such as in `main.ts` or the root component. If you import `dynamsoft.config.ts` within a specific subcomponent, you can achieve lazy loading, which can save bandwidth by only loading the barcode feature when needed.
-
-Next, we will demonstrate how to introduce `dynamsoft.config.ts` into a specific component. Don't skip the [Component for Reading Image](#component-for-reading-image) section even if you only need video barcode decoding.
-
-## Component for Reading Image
-
-A component's lifecycle includes creation and destruction, making it difficult to ensure that a component won't be rebuilt. Since the [CaptureVisionRouter](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html?product=dbr&lang=javascript#capturevisionrouter-class) object is associated with a [Worker](https://developer.mozilla.org/en-US/docs/Web/API/Worker), it cannot be automatically garbage collected. Therefore, we need to manually [dispose](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/instantiate.html?product=dbr&lang=javascript#dispose) of it.
-
-```ts
-import "../../dynamsoft.config";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cvRouter;
-
-// create cvRouter before it's needed
-// for example, after the component is mounted
-async mounted(){
-  cvRouter = await CaptureVisionRouter.createInstance();
-}
-
-// dispose cvRouter when it's no longer needed
-beforeUnmount(){
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-```
-
-In scenarios where users may click the button quickly, the component might be destroyed before `cvRouter` is fully created. To handle this situation, we'll need to implement some techniques to ensure proper resource management.
-
-Here's an improved version of the code to address this issue:
-
-```ts
-let pCvRouter; // promise of cvRouter
-
-// create cvRouter before it's needed
-// for example, after the component is mounted
-async mounted(){
-  cvRouter = await (pCvRouter = CaptureVisionRouter.createInstance());
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  await pCvRouter; // ensure cvrouter creation is complete
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-```
-
-### Reading Barcode from an Uploaded File
-
-In some cases, you might need to read barcode from an uploaded file. Here's how to handle that in your component.
-
-```tsx
-import { EnumCapturedResultItemType } from "dynamsoft-core";
-
-async function captureImage(e: Event){
-  // Some frameworks will wrap the event. Refer to DBRJS samples of each frameworks for details
-  let file = e.target.files[0];
-  e.target.value = ''; // reset input
-
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  for (let item of result.items) {
-    // check if captured result item is a barcode
-    if(item.type !== EnumCapturedResultItemType.CRIT_BARCODE) { 
-      continue; // Skip processing if the result is not a barcode
-    } 
-    console.log(item.text); // output the decoded barcode text
-  }
-}
-
-// usage example in a tsx/jsx component
-<input type="file" onChange={captureImage}>
-```
-
-### Lazy Loading `cvRouter`
-
-To optimize resource usage, you might want to lazy load `cvRouter` only after the client uploads a file.
-
-```ts
-async captureImage(e: Event){
-  // ...
-  cvRouter = await (pCvRouter = CaptureVisionRouter.createInstance());
-  // ...
-}
-```
-
-Additionally, users may repeatedly upload files which can result in multiple instances being created, potentially causing memory leaks. Here's how we could handle this.
-
-```ts
-async captureImage(e: Event){
-  // ...
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  // ...
-}
-```
-
-### Handling Component Destruction During Decoding
-
-When decoding barcodes, it's common for users to switch to another component. If you're familiar with handling network requests, you know that this situation is very common.
-
-Here's how we could handle with proper checks to avoid program errors:
-
-```ts
-let isDestroyed = false;
-
-async captureImage(e: Event){
-  // ensure cvRouter is created only once
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-  // ...
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  if(isDestroyed){ return; }
-
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCvRouter;
-  cvRouter?.dispose();
-  cvRouter = null;
-}
-```
-
-By adding a check for `isDestroyed` after each `await`, we can ensure that the code handles the component's potential destruction properly, avoiding errors and resource leaks.
-
-### Complete Code Example
-
-```tsx
-import "../../dynamsoft.config";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cvRouter;
-let pCvRouter; // promise of cvRouter
-let isDestroyed = false;
-
-async captureImage(e: Event){
-  // Some frameworks will wrap the event. Refer to DBRJS samples of each frameworks for details
-  let file = e.target.files[0];
-  e.target.value = ''; // reset input
-
-  // ensure cvRouter is created only once
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  if(isDestroyed){ return; }
-
-  for (let item of result.items) {
-    // check if captured result item is a barcode
-    if(item.type !== EnumCapturedResultItemType.CRIT_BARCODE) { 
-      continue; // Skip processing if the result is not a barcode
-    } 
-    console.log(item.text); // output the decoded barcode text
-  }
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCvRouter; // ensure cvrouter creation is complete
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-
-// usage example in a tsx/jsx component
-<input type="file" onChange={captureImage}>
-```
-
-> If you find it difficult to think about these, don't worry, just go to [DBRJS samples for framework](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/hello-world), copy these components into your project.

-## Component for Decoding Video
-
-### Set up the video ([CameraView](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/cameraview.html)) container
-
-To render video within a component and handle its lifecycle properly, we can use framework's methods (such as `#` or `ref` or `bind:this`) to get the component's `HTMLDivElement`. This is where the video will be rendered.
-
-```tsx
-let cameraviewContainer;
-
-<div ref={cameraViewContainer}></div>
-```
-
-### Render the Video UI
-
-The [`CameraEnhancer`](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/index.html) instance needs to be properly created and [disposed](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/instantiate.html#dispose) of to manage resources.
-
-```ts
-import "../dynamsoft.config";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-
-let cameraEnhancer;
-let pCameraEnhancer; // promise of cameraEnhancer
-let isDestroyed = false;
-
-async mount(){
-  // create a `CameraEnhancer` instance for camera control and a `CameraView` instance for UI control.
-  const cameraView = await CameraView.createInstance();
-  if(isDestroyed){ return; } // Check if component is destroyed after every async
-
-  cameraEnhancer = await (pCameraEnhancer || CameraEnhancer.createInstance(cameraView));
-  if(isDestroyed){ return; }
-
-  // Get default UI and append it to DOM.
-  cameraViewContainer.append(cameraView.getUIElement());
-}
-
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCameraEnhancer;
-  cameraEnhancer?.dispose();
-  cameraEnhancer = null;
-}
-
-// usage example in a tsx/jsx component
-<div ref={cameraViewContainer}></div>
-```
-
-### Add [`CaptureVisionRouter`](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html)
-
-To complete the code, we'll include the [`CaptureVisionRouter`](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html) and handle it's life cycle similarly.
-
-```ts
-import "../dynamsoft.config";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cameraEnhancer;
-let pCameraEnhancer; // promise of cameraEnhancer
-let cvRouter;
-let pCvRouter; // promise of cvRouter
-let isDestroyed = false;
-
-async mount(){
-  // Create a `CameraEnhancer` instance for camera control and a `CameraView` instance for UI control.
-  const cameraView = await CameraView.createInstance();
-  if(isDestroyed){ return; } // Check if component is destroyed after every async
-  
-  cameraEnhancer = await (pCameraEnhancer || CameraEnhancer.createInstance(cameraView));
-  if(isDestroyed){ return; }
-
-  // Get default UI and append it to DOM.
-  cameraViewContainer.append(cameraView.getUIElement());
-
-  // Create a `CaptureVisionRouter` instance and set `CameraEnhancer` instance as its image source.
-  cvRouter = await (pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-
-  cvRouter.setInput(cameraEnhancer);
-
-  // Define a callback for results.
-  cvRouter.addResultReceiver({ onDecodedBarcodesReceived: (result) => {
-    if (!result.barcodeResultItems.length) return;
-    for (let item of result.barcodeResultItems) {
-      console.log(item.text); // output the decoded barcode text
-    }
-  }});
-
-  // Filter out unchecked and duplicate results.
-  const filter = new MultiFrameResultCrossFilter();
-  // Filter out unchecked barcodes.
-  filter.enableResultCrossVerification("barcode", true);
-  // Filter out duplicate barcodes within 3 seconds.
-  filter.enableResultDeduplication("barcode", true);
-  await cvRouter.addResultFilter(filter);
-  if(isDestroyed){ return; }
-
-  // Open camera and start scanning single barcode.
-  await cameraEnhancer.open();
-  if(isDestroyed){ return; }
-
-  await cvRouter.startCapturing("ReadSingleBarcode");
-}
-
-async beforeUnmount(){
-  isDestroyed = true;
-
-  await pCvRouter;
-  cvRouter?.dispose();
-  cvRouter = null;
-
-  await pCameraEnhancer;
-  cameraEnhancer?.dispose();
-  cameraEnhancer = null;
-}
-
-// usage example in a tsx/jsx component

-# Use in Framework - User Guide
-
-Integrating [Dynamsoft Barcode Reader JavaScript Edition](https://www.dynamsoft.com/barcode-reader/sdk-javascript/) (DBR-JS) into frameworks like Angular, React, and Vue is a little different compared to native usage. This guide will quickly explain the common practices of integrating DBR-JS into these frameworks.
-
-You can also refer to [the ready-made samples for popular frameworks](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/foundational-api-samples/hello-world) directly without reading this guide.
-
-## Installation
-
-Assuming you have an existing project using a framework, you should have a `package.json` file in your project's root directory.
-
-1. Open the terminal from your project root directory.
-2. Install DBR-JS SDK with the following command:
-
-    ```sh
-    npm install dynamsoft-barcode-reader-bundle@11.0.6000 -E
-    ```
-
-3. Confirm the installation by checking the `package.json`. You should see:
-
-    ```json
-    {
-      ...
-      "dependencies": {
-        ...
-        "dynamsoft-barcode-reader-bundle": "11.0.6000"
-      }
-    }
-    ```
-
-Notice that there is no `^` before `11.0.6000`. No `^` indicates an exact version, ensuring stability and avoids automatic upgrades even without `package-lock.json`.
-
-While we keep the SDK's external interface relatively stable, the SDK's internal communication often change with each new version. These changes can potentially lead to compatibility issues with `engineResourcePaths` settings. To prevent any unexpected difficulties and surprises, it's essential to use the exact version of the SDK.
-
-## Configuration
-
-Next, we'll create a Configuration file for the common settings related to DBR-JS. If you use TypeScript, we can name the file `dynamsoft.config.ts`. This file is not a component, so you can place it under the `lib` directory or the root directory of `src`.
-
-```ts
-import { CoreModule } from "dynamsoft-core";
-import { LicenseManager } from "dynamsoft-license";
-import "dynamsoft-barcode-reader";
-
-// Configures the root path where the .wasm files and other necessary resources for modules are located.
-CoreModule.engineResourcePaths.rootDirectory = "https://cdn.jsdelivr.net/npm/";
-
-/** LICENSE ALERT - README

-
-/**

- * LICENSE ALERT - THE END
- */
-
-// Optional. Preload "BarcodeReader" module for reading barcodes. It will save time on the initial decoding by skipping the module loading.
-CoreModule.loadWasm();
-```
-
-In order for these settings to take effect, `dynamsoft.config.ts` must be imported before using the barcode reader. One approach is to import this file at the entry point of the application, such as in `main.ts` or the root component. If you import `dynamsoft.config.ts` within a specific subcomponent, you can achieve lazy loading, which can save bandwidth by only loading the barcode feature when needed.
-
-### Offline usage
-
-In some cases, you may need to use DBR-JS in an offline environment. You can download the [DBR-JS zip](https://www.dynamsoft.com/barcode-reader/downloads/1000003-confirmation/#js) package through the link, which contains all the necessary offline resources in the `./distributables` directory.
-
-**Step 1:** Copy the `./distributables` folder to your project.
-
-**Step 2:** In `dynamsoft.config.ts`, define the `engineResourcePaths`:
-
-```javascript
-// Configures the root path where the .wasm files and other necessary resources for modules are located. Feel free to change it to your own location of these files
-CoreModule.engineResourcePaths.rootDirectory = '../assets/distributables';
-```
-
-> Note:
-> 
-> We recommend not renaming any module files within the `./distributables` directory, as this may cause the rootDirectory configuration to not work properly. In such cases, you would need to define resource paths for each module individually.
-> In our case the packages are used only as static resources, we recommend moving the `./distributables` to a dedicated folder for static resources in your project to facilitate self-hosting.
-
-Next, we will demonstrate how to introduce `dynamsoft.config.ts` into a specific component. Don't skip the [Component for Reading Image](#component-for-reading-image) section even if you only need video barcode decoding.

-      continue; // Skip processing if the result is not a barcode
-    } 
-    console.log(item.text); // output the decoded barcode text
-  }
-}

-
-### Lazy Loading `cvRouter`
-
-To optimize resource usage, you might want to lazy load `cvRouter` only after the client uploads a file.
-
-```ts
-async captureImage(e: Event){
-  // ...
-  cvRouter = await (pCvRouter = CaptureVisionRouter.createInstance());
-  // ...
-}
-```
-
-Additionally, users may repeatedly upload files which can result in multiple instances being created, potentially causing memory leaks. Here's how we could handle this.
-
-```ts
-async captureImage(e: Event){
-  // ...
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  // ...
-}
-```
-
-### Handling Component Destruction During Decoding
-
-When decoding barcodes, it's common for users to switch to another component. If you're familiar with handling network requests, you know that this situation is very common.
-
-Here's how we could handle with proper checks to avoid program errors:
-
-```ts
-let isDestroyed = false;
-
-async captureImage(e: Event){
-  // ensure cvRouter is created only once
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-  // ...
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  if(isDestroyed){ return; }
-
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCvRouter;
-  cvRouter?.dispose();
-  cvRouter = null;
-}
-```
-
-By adding a check for `isDestroyed` after each `await`, we can ensure that the code handles the component's potential destruction properly, avoiding errors and resource leaks.
-
-### Complete Code Example
-
-```tsx
-import "../../dynamsoft.config";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cvRouter;
-let pCvRouter; // promise of cvRouter
-let isDestroyed = false;
-
-async captureImage(e: Event){
-  // Some frameworks will wrap the event. Refer to DBRJS samples of each frameworks for details
-  let file = e.target.files[0];
-  e.target.value = ''; // reset input
-
-  // ensure cvRouter is created only once
-  cvRouter = await (pCvRouter = pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-
-  let result = await cvRouter.capture(file, "ReadBarcodes_SpeedFirst");
-  if(isDestroyed){ return; }
-
-  for (let item of result.items) {
-    // check if captured result item is a barcode
-    if(item.type !== EnumCapturedResultItemType.CRIT_BARCODE) { 
-      continue; // Skip processing if the result is not a barcode
-    } 
-    console.log(item.text); // output the decoded barcode text
-  }
-}
-
-// dispose cvRouter when it's no longer needed
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCvRouter; // ensure cvrouter creation is complete
-  cvRouter?.dispose(); // dispose cvRouter if it exists
-  cvRouter = null; // reset cvRouter to null
-}
-
-// usage example in a tsx/jsx component
-<input type="file" onChange={captureImage}>
-```

-## Component for Decoding Video
-
-### Set up the video ([CameraView](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/cameraview.html)) container
-
-To render video within a component and handle its lifecycle properly, we can use framework's methods (such as `#` or `ref` or `bind:this`) to get the component's `HTMLDivElement`. This is where the video will be rendered.
-
-```tsx
-let cameraviewContainer;
-
-<div ref={cameraViewContainer}></div>
-```
-
-### Render the Video UI
-
-The [`CameraEnhancer`](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/index.html) instance needs to be properly created and [disposed](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/instantiate.html#dispose) of to manage resources.
-
-```ts
-import "../dynamsoft.config";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-
-let cameraEnhancer;
-let pCameraEnhancer; // promise of cameraEnhancer
-let isDestroyed = false;
-
-async mount(){
-  // create a `CameraEnhancer` instance for camera control and a `CameraView` instance for UI control.
-  const cameraView = await CameraView.createInstance();
-  if(isDestroyed){ return; } // Check if component is destroyed after every async
-
-  cameraEnhancer = await (pCameraEnhancer || CameraEnhancer.createInstance(cameraView));
-  if(isDestroyed){ return; }
-
-  // Get default UI and append it to DOM.
-  cameraViewContainer.append(cameraView.getUIElement());
-}
-
-async beforeUnmount(){
-  isDestroyed = true;
-  await pCameraEnhancer;
-  cameraEnhancer?.dispose();
-  cameraEnhancer = null;
-}
-
-// usage example in a tsx/jsx component
-<div ref={cameraViewContainer}></div>
-```
-
-### Add [`CaptureVisionRouter`](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html)
-
-To complete the code, we'll include the [`CaptureVisionRouter`](https://www.dynamsoft.com/capture-vision/docs/web/programming/javascript/api-reference/capture-vision-router/capture-vision-router-module.html) and handle it's life cycle similarly.
-
-```ts
-import "../dynamsoft.config";
-import { CameraEnhancer, CameraView } from "dynamsoft-camera-enhancer";
-import { CaptureVisionRouter } from "dynamsoft-capture-vision-router";
-
-let cameraEnhancer;
-let pCameraEnhancer; // promise of cameraEnhancer
-let cvRouter;
-let pCvRouter; // promise of cvRouter
-let isDestroyed = false;
-
-async mount(){
-  // Create a `CameraEnhancer` instance for camera control and a `CameraView` instance for UI control.
-  const cameraView = await CameraView.createInstance();
-  if(isDestroyed){ return; } // Check if component is destroyed after every async
-  
-  cameraEnhancer = await (pCameraEnhancer || CameraEnhancer.createInstance(cameraView));
-  if(isDestroyed){ return; }
-
-  // Get default UI and append it to DOM.
-  cameraViewContainer.append(cameraView.getUIElement());
-
-  // Create a `CaptureVisionRouter` instance and set `CameraEnhancer` instance as its image source.
-  cvRouter = await (pCvRouter || CaptureVisionRouter.createInstance());
-  if(isDestroyed){ return; }
-
-  cvRouter.setInput(cameraEnhancer);
-
-  // Define a callback for results.
-  cvRouter.addResultReceiver({ onDecodedBarcodesReceived: (result) => {
-    if (!result.barcodeResultItems.length) return;
-    for (let item of result.barcodeResultItems) {
-      console.log(item.text); // output the decoded barcode text
-    }
-  }});
-
-  // Filter out unchecked and duplicate results.
-  const filter = new MultiFrameResultCrossFilter();
-  // Filter out unchecked barcodes.
-  filter.enableResultCrossVerification("barcode", true);
-  // Filter out duplicate barcodes within 3 seconds.
-  filter.enableResultDeduplication("barcode", true);
-  await cvRouter.addResultFilter(filter);
-  if(isDestroyed){ return; }
-
-  // Open camera and start scanning single barcode.
-  await cameraEnhancer.open();
-  if(isDestroyed){ return; }
-
-  await cvRouter.startCapturing("ReadSingleBarcode");
-}
-
-async beforeUnmount(){
-  isDestroyed = true;
-
-  await pCvRouter;
-  cvRouter?.dispose();
-  cvRouter = null;
-
-  await pCameraEnhancer;
-  cameraEnhancer?.dispose();
-  cameraEnhancer = null;
-}
-
-// usage example in a tsx/jsx component
-<div ref={cameraViewContainer}></div>
-```

-### Final Notes
-
-Decoding video is slightly more complex than reading image, but by following the steps above, you can manage resources effectively and ensure your component runs smoothly.
-
-Again, if you don't want to go into detail, please refer to the [DBRJS sample](https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/main/hello-world) directly.
-
-Note that since we have taken over native rendering, avoid changing the UI through the framework within decoding video component; instead, make changes in its parent component.
-
-Once this component is rendered, decoding will start. You can control when decoding occurs by not rendering this component until needed.
