L_INT pEXT_CALLBACK YourFunction(nRecogPage, nError, pUserData)
Reports the status of the recognized page.
Zero-based index for the recognized page.
Specifies the error returned from the recognition process.
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 pUserData parameter of the L_Doc2Recognize / L_Doc2RecognizeExt function.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
RECOGNIZESTATUSCALLBACK2 is invoked after recognizing each page. It reports the recognized page's index with the error code (status) that was returned from the recognition process.
RECOGNIZESTATUSCALLBACK2 is invoked by a call to the L_Doc2Recognize / L_Doc2RecognizeExt function.
If RECOGNIZESTATUSCALLBACK2 returns an error code < SUCCESS, the recognition process is terminated, and no more pages processed.
When RECOGNIZESTATUSCALLBACK2 returns SUCCESS, recognition continues.
