L_LTDOC_API L_INT L_DocSaveResultsToMemory(hDoc, ppBuffer, plSize)

L_HDOC hDoc;	/* handle to the OCR document */
L_UCHAR ** ppBuffer;	/* address to buffer to be updated */
L_INT32 * plSize;	/* pointer to be updated */

Saves the last recognition process result to memory.

Parameter	Description
hDoc	Handle to the OCR document.
ppBuffer	Address of a pointer to be filled with the address of the final output document in memory.
plSize	Address of a variable to be updated with the length of the final output document.

Returns

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

Comments

To free the memory associated with the recognition results, call L_DocFreeMemoryResults.

Call L_DocSaveResultsToMemory after the recognition process is complete to save the results to memory.

To recognize one or more pages, call L_DocRecognize.

To save the recognition results to a file, call L_DocSaveResultsToFile.
