Some of the OCR engines supported by LEADTOOLS (for example, the OcrEngineType.Plus and OcrEngineType.Professional) support saving the recognition results using the engine native save mechanism instead of the LEADTOOLS Document Writers. Use the GetSupportedEngineFormats method to get a list of the names of the native formats and the EngineFormat property to set the format to use when saving the results.

It is recommended that you use the LEADTOOLS Document Writers supported formats always when saving OCR recognition data. For more information refer to Leadtools.Forms.DocumentWriters.DocumentFormat. Support for native engine formats may be deprecated in later versions of LEADTOOLS.

To save the recognition results using the engine native format:

Obtain the engine native format name using the GetSupportedEngineFormats.
Set the engine format name with the EngineFormat property
Call the various save methods (IOcrDocument.Save or IAutoRecognizeManager.Run) using DocumentFormat.User for the format parameter.

Note that the LEADTOOLS default installation does not ship with native engine format support. You must download and install the "OCR Additional Features" setup available at http://www.leadtools.com to add this feature. To get a list of the engine native formats available but not installed for the current OCR engine, use GetAdditionalEngineFormats.

For more information about the various document formats supported by LEADTOOLS refer to Leadtools.Forms.DocumentWriters.DocumentFormat.

To determine whether a specific engine native format is supported by this IOcrEngine, use IsEngineFormatSupported.

To get the file extension for a specific engine native format, use GetEngineFormatFileExtension.

To get the friendly name for a specific engine native format, use GetEngineFormatFriendlyName.

For an example, refer to IOcrDocumentManager.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
