DSIntermediateResultManager

The DSIntermediateResultManager class manages intermediate results generated during data capturing. It provides methods to add and remove intermediate result receivers, as well as to get original image data using an image hash id.

Definition

Assembly: DynamsoftCore.framework

>- Objective-C >- Swift > >1. ```objc @interface DSIntermediateResultManager: NSObject ``` 2. ```swift class IntermediateResultManager : NSObject ```

Methods

Method	Description
addResultReceiver	Adds an intermediate result receiver.
removeResultReceiver	Removes an intermediate result receiver.
getOriginalImage	Gets the original image data using the image's hash ID.

addResultReceiver

Adds an intermediate result receiver to an IntermediateResultManager object.

>- Objective-C >- Swift > >1. ```objc - (BOOL)addResultReceiver:(id)receiver; ``` 2. ```swift func addResultReceiver(_ receiver: DSIntermediateResultReceiver) ```

Parameters

receiver: A delegate object of DSIntermediateResultReceiver.

Return Value

A BOOL value that indicates whether the result receiver is added successfully.

Code Snippet

>- Objective-C >- Swift > >1. ```objc BOOL result = [resultManager addResultReceiver:receiver]; ``` 2. ```swift resultManager.addResultReceiver(receiver) ```

removeResultReceiver

Removes an intermediate result receiver from an IntermediateResultManager object.

>- Objective-C >- Swift > >1. ```objc - (BOOL)removeResultReceiver:(id)receiver; ``` 2. ```swift func removeResultReceiver(_ receiver: DSIntermediateResultReceiver) ```

Parameters

receiver: A delegate object of DSIntermediateResultReceiver.

Return Value

A BOOL value that indicates whether the result receiver is removed successfully.

Code Snippet

>- Objective-C >- Swift > >1. ```objc result = [resultManager removeResultReceiver:receiver]; ``` 2. ```swift resultManager.removeResultReceiver(receiver) ```

getOriginalImage

Gets the original image data using the image's hash ID.

>- Objective-C >- Swift > >1. ```objc - (DSImageData)getOriginalImage:(NSString)imageHashId; ``` 2. ```swift func getOriginalImage(_ imageHashId: String) -> DSImageData ```

Parameters

imageHashId: The image hash ID.

Return Value

The original image data as DSImageData.
