The OcrEngineManager class and its methods are your entry to using the Leadtools.Ocr class library.
There are two things to consider when creating an IOcrEngine instance:
OCR Engine Type The LEADTOOLS for .NET class library supports multiple OCR engines. All engines supported implement the same interfaces defined in Leadtools.Ocr.dll. As a result, it is not necessary to change the application code when switching engines.
The first parameter of the OcrEngineManager.CreateEngine method (engineType) is a value of the OcrEngineType enumeration. It specifies which OCR engine to load. Internally, the framework uses Assembly.Load to load the corresponding assembly and create the objects that implement the various public interfaces (for example, IOcrEngine).
Currently, the LEADTOOLS for .NET class library supports the following engines:
LEADTOOLS OCR Module - LEAD Engine engine. The OCR library inside Leadtools.Ocr.LEADEngine.dll is loaded.
LEADTOOLS OCR Module - OmniPage Engine engine. The OCR library inside Leadtools.Ocr.OminPageEngine.dll is loaded.
LEADTOOLS OCR Module - OmniPage Engine with Additional Languages engine. The OCR library inside Leadtools.Ocr.OmniPageArabicEngine.dll is loaded.
