The LEADTOOLS OCR engines provide support for recognizing document zones in separate threads. This can improve the performance of the recognition process. Control the number of threads through Leadtools.Services.Forms.ServiceImplementations.dll.config by setting the value for MaximumRecognitionThreads to one of the following:
Also LEADTOOLS OCR engines provide support for auto-zoning in separate threads. This can improve the performance of the recognition process. Disable and enable this option through Leadtools.Services.Forms.ServiceImplementations.dll.config by setting the value for EnableMultiThreadingZoning to one of the following:
