It is the user's responsibility to dispose of this object when it is no longer needed by calling Dispose.
ocrEngines should be provided. If it is null, an exception is thrown.
If barcodeEngine is null, Leadtools.Forms.Recognition.Barcode.BarcodeObjectsManager will not be used for recognition and Leadtools.Forms.Processing.BarcodeFormField will not be processed.
The MinimumConfidenceRecognized is set to 90, MinimumConfidenceKnownForm is set to 30, and RecognizeFirstPageOnly is set to false.
The recognition Object Managers will be set to the managers used to generate the Master Forms in the repository.
To implement your own multiple thread or to not use threads use AutoFormsEngine(IMasterFormsRepository repository, List<IOcrEngine> ocrEngines, BarcodeEngine barcodeEngine).
Using Multiple threads is recommended since it speeds up form recognition and processing.
