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.
Multi-threading is recommended since it speeds up form recognition and processing.
To implement your own multiple thread or to not use threads use AutoFormsEngine(IMasterFormsRepository repository, List<IOcrEngine> ocrEngines, BarcodeEngine barcodeEngine, AutoFormsRecognitionManager managers, int minimumConfidenceKnownForm, int minimumConfidenceRecognized, bool recognizeFirstPageOnly).
