L_LTDOC2_API L_INT EXT_FUNCTION L_Doc2SaveResultsToFile2(hDoc, pszFileName, uFlags)

L_HDOC2 hDoc;	/* handle to the OCR document */
L_TCHAR * pszFileName;	/* the output file name */
L_UINT uFlags;	/* flags determines the function behavior */

Saves the recognition results to a file

Parameter	Description
hDoc	Handle to the OCR document.
pszFileName	Character string, which contains the name of the output file to be saved.
uFlags	Flag that determines the function behavior. Possible values are:
	Value	Meaning
	0	The default behavior. It works as L_Doc2SaveResultsToFile.
	DOC2_SAVE_PAGE_RESULTS	[0x001] Saves all page(s) results before saving it to final results.

Returns

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

Comments

To recognize one or more pages, call the L_Doc2Recognize function.

To set save recognition results options, call the L_Doc2SetRecognitionResultOptions function.

To get the current save recognition results options, call the L_Doc2GetRecognitionResultOptions function.

To get all supported output formats, call the L_Doc2EnumOutputFileFormats function.

To get the format options, call the L_Doc2GetOutputFormatSettings function, and to update the format options, call the L_Doc2SetOutputFormatSettings function

Use L_Doc2SaveResultsToFile2 when you want to save the recognition results to different formats using the same recognition results while maintaining quality. Use L_Doc2SaveResultsToFile when memory is a constraint (it uses less memory than L_Doc2SaveResultsToFile2). However, L_Doc2SaveResultsToFile requires OCR to be performed separately for each file format in order to maintain quality.
