Comments

Gets the options for the format the document writer is to use to write results.

To specify a document writer format, fill the DocFormat member of the RESULTOPTIONS structure and pass it to the L_DocSetRecognitionResultOptions function.

To set the options for a specific document writer format, call the L_DocSetDocumentWriterOptions function.

After setting the document format and options, call L_DocSaveResultsToFile to save the results.
