}

Remarks

This method must be called before calling any other Leadtools OCR document toolkit method. The user must unlock the OCR document toolkit using the Unlock method. If the OCR document toolkit is locked then the Startup method will fail and will not initialize the OCR document toolkit. This method will load and start the OCR document engine. For each call to Startup there must be a call to the Shutdown method. For more information, refer to Starting and Shutting Down the Engine.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
