OcrAutoRecognizeJobProgressEventArgs Class

Summary

Contains data for the IOcrAutoRecognizeManager.JobProgress event.

Syntax

C++/CLI

Python

[SerializableAttribute()] 
public class OcrAutoRecognizeJobProgressEventArgs : EventArgs

[SerializableAttribute()] 
public ref class OcrAutoRecognizeJobProgressEventArgs : public System.EventArgs

class OcrAutoRecognizeJobProgressEventArgs(EventArgs):

Remarks

This is the equivalent of using standard OCR progress callbacks with the IOcrAutoRecognizeManager, the Data member will contain the same data passed to OcrProgressCallback.

Note that the IOcrAutoRecognizeManager.JobProgress will only occur if one thread is used during the recognition process.

IOcrAutoRecognizeManager allows you to modify the raster image, OCR page or OCR document during some parts of the operation. Refer to OcrAutoRecognizeJobOperationEventArgs.PageImage for more information an example.
