L_Doc2SaveResultsToFileExt

#include "ltdoc2.h"

L_LTDOC2_API L_INT L_Doc2SaveResultsToFileExt(hDoc, nDocId, pszFileName, uFlags)

Saves the recognition results to a file.

Parameters

L_HDOC2 hDoc

Handle to the OCR document.

L_INT nDocId

Document ID created by calling L_Doc2CreateDocument.

L_TCHAR * pszFileName

Character string, containing the name of the output file to be saved.

L_UINT uFlags

Flags that determine function behavior.  Possible values are:

Returns

Comments

To recognize one or more pages, call the L_Doc2Recognize / L_Doc2RecognizeExt function.

Set save recognition results options by calling L_Doc2SetRecognitionResultOptions / L_Doc2SetRecognitionResultOptionsExt.

To get the current save recognition results options, call the L_Doc2GetRecognitionResultOptions / L_Doc2GetRecognitionResultOptionsExt function.

Get all supported output formats by calling L_Doc2EnumOutputFileFormats.

To get format options, call the L_Doc2GetOutputFormatSettings / L_Doc2GetOutputFormatSettingsExt function. To update 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, 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).
