public AutoFormsEngine(IMasterFormsRepository repository,IOcrEngine ocrEngine,BarcodeEngine barcodeEngine,AutoFormsRecognitionManager managers,int minimumConfidenceKnownForm,int minimumConfidenceRecognized,bool recognizeFirstPageOnly)
repository
Repository of Master Forms.
ocrEngine
The Leadtools.Ocr.IOcrEngine that is used for optical character recognition and processing.
barcodeEngine
The Leadtools.Barcode.BarcodeEngine that is used for barcode recognition and processing.
managers
The Object Managers to be used to recognize forms and generate Master Forms attributes in GenerateMasterFormAttributes.
minimumConfidenceKnownForm
The minimum confidence value to decide that the Form type result is a known type. It ranges from 0 to 100 and usually it is less than minimumConfidenceRecognized.
minimumConfidenceRecognized
The minimum confidence value to decide that the Form type is recognized and no further comparison with Master Forms is needed. It ranges from 0 to 100 and usually it is greater than minimumConfidenceKnownForm.
recognizeFirstPageOnly
Recognize the form based on the first page only.
It is the user's responsibility to dispose of this object when it is no longer needed by calling Dispose.
If ocrEngine is null, Leadtools.Forms.Recognition.Ocr.OcrObjectsManager will not be used for recognition and Leadtools.Forms.Processing.TextFormField and Leadtools.Forms.Processing.OmrFormField will not be processed.
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 recognition Object Managers will be set to the managers used to generate the Master Forms in the repository.
Important: Different OCR engines might have slight differences in form alignment and recognition. Therefore, it is best to use the same Leadtools.Ocr.OcrEngineType when generating the master forms and when recognizing and processing forms.
