Example
Remarks
When a runtime error occurs in the IOcrEngine, an exception of type OcrException is thrown with the engine-specific error code set in the Code member. This error code is engine-specific but a short description can be obtained using the System.Exception.Message property of this class or by using the IOcrEngine.GetErrorCodeString method.
Logic errors such as invalid parameters to methods or invalid operations throw standard .NET exceptions (in this case, System.ArgumentException and System.InvalidOperationException respectively Errors caused by loading invalid image files using IOcrEngine.RasterCodecsInstance will throw exceptions of type Leadtools.RasterException. Errors for missing features (support locked) will throw OcrSupportLockedException exceptions. Any other runtime error in the engine will throw an OcrException.
