L_LTDOC2_API L_INT EXT_FUNCTION L_Doc2SaveResultsToFile(hDoc, pszFileName)
Saves the recognition results to a file.
Handle to the OCR document.
Character string, which contains the name of the output file to be saved.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
To recognize one or more pages, call the L_Doc2Recognize / L_Doc2RecognizeExt function.
To set save recognition results options, call the L_Doc2SetRecognitionResultOptions / L_Doc2SetRecognitionResultOptionsExt function.
Get the current save recognition results options by calling L_Doc2GetRecognitionResultOptions / L_Doc2GetRecognitionResultOptionsExt.
To get all supported output formats, call the L_Doc2EnumOutputFileFormats function.
Get the format options by calling L_Doc2GetOutputFormatSettings / L_Doc2GetOutputFormatSettingsExt, and to update the format options, call the L_Doc2SetOutputFormatSettings / L_Doc2SetOutputFormatSettingsExt function.
Use L_Doc2SaveResultsToFile2 to save the recognition results to different formats using the same recognition results and at the same time maintain quality. However, it consumes more memory than L_Doc2SaveResultsToFile / L_Doc2SaveResultsToFileExt.
If memory is a constraint, use L_Doc2SaveResultsToFile / L_Doc2SaveResultsToFileExt instead. However, note that **L_Doc2SaveResultsToFile / L_Doc2SaveResultsToFileExt requires OCR to be performed separately for each file format in order to maintain quality.
The difference between L_Doc2SaveResultsToFile and L_Doc2SaveResultsToFileExt is that L_Doc2SaveResultsToFileExt includes the document ID parameter (nDocId).
