L_OcrAutoRecognizeJobOperationCallback

Summary

You can use this callback to get information on the current auto recognize operation (creating an OCR document, loading a page, zoning, recognizing, saving, etc.). The address of this callback is passed as an argument to the L_OcrAutoRecognizeManager_SetJobOperationCallback function.

Syntax

#include "ltocr.h"

L_INT pEXT_CALLBACK YourFunction(data, userData)

Parameters

const L_OcrAutoRecognizeJobOperationCallbackData* data

Pointer to a L_OcrAutoRecognizeJobOperationCallbackData structure that contains information on the current auto recognize operation.

L_VOID * userData

A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the userData parameter of the L_OcrAutoRecognizeManager_SetJobOperationCallback function.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

This callback gets called when L_OcrAutoRecognizeManager_Run, L_OcrAutoRecognizeManager_RunJob or L_OcrAutoRecognizeManager_RunJobAsync is called.

To activate the progress callback function, call the L_OcrAutoRecognizeManager_SetJobOperationCallback function.
