Comments

Saves the recognition results to a file.

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.
