getLocalizedBarcodes

Get all localized barcodes.

>- Objective-C >- Swift > >1. ```objc - (nullable NSArray *)getLocalizedBarcodes ``` 2. ```swift func getLocalizedBarcodes() -> [LocalizedBarcodeElement]? ```

Return Value

An array of LocalizedBarcodeElement as the localized barcodes.

getCount

Get the count of localized barcodes.

>- Objective-C >- Swift > >1. ```objc - (NSInteger)getCount ``` 2. ```swift func getCount() -> Int ```

Return Value

The count of localized barcodes.

getLocalizedBarcode

Get the LocalizeBarcodeElement at the specified index.

>- Objective-C >- Swift > >1. ```objc - (DSLocalizedBarcodeElement *)getLocalizedBarcode:(NSInteger)index ``` 2. ```swift func getLocalizedBarcode(_ index: Int) -> LocalizedBarcodeElement? ```

Parameters

[in] index: The index of the localized barcode.

Return Value

The LocalizeBarcodeElement at the specified index.

removeAllLocalizedBarcodes

Remove all localized barcodes.

>- Objective-C >- Swift > >1. ```objc - (void)removeAllLocalizedBarcodes ``` 2. ```swift func removeAllLocalizedBarcodes() ```

removeLocalizedBarcode

Remove the LocalizedBarcodeElement from the unit at the specified index.

>- Objective-C >- Swift > >1. ```objc - (void)removeLocalizedBarcode:(NSInteger)index ``` 2. ```swift func removeLocalizedBarcode(_ index: Int) ```

Parameters

[in] index: The index of the localized barcode.

addLocalizedBarcode

Add a new LocalizedBarcodeElement to the unit.

>- Objective-C >- Swift > >1. ```objc -(NSInteger)addLocalizedBarcode:(DSLocalizedBarcodeElement*)element matrixToOriginalImage:(CGAffineTransform)matrixToOriginalImage; ``` 2. ```swift func addLocalizedBarcode(_ element: LocalizedBarcodeElement, matrixToOriginalImage: CGAffineTransform) -> Int ```

Parameters

[in] element: The LocalizedBarcodeElement to add.

[in] matrixToOriginalImage: The transformation matrix from the original image to the unit.

Return Value

Returns the ErrorCode if failed. Otherwise, returns 0.

setLocalizedBarcode

Set the LocalizedBarcodeElement at the specified index.

>- Objective-C >- Swift > >1. ```objc -(NSInteger)setLocalizedBarcode:(NSInteger)index element:(DSLocalizedBarcodeElement*)element matrixToOriginalImage:(CGAffineTransform)matrixToOriginalImage; ``` 2. ```swift func setLocalizedBarcode(_ index: Int, element: LocalizedBarcodeElement, matrixToOriginalImage: CGAffineTransform) -> Int ```

Parameters

[in] index: The index of the localized barcode.

[in] element: The LocalizedBarcodeElement to set.

[in] matrixToOriginalImage: The transformation matrix from the original image to the unit.

Return Value

Returns the ErrorCode if failed. Otherwise, returns 0.
