Java

Python

public void ProcessForm( 
   LEADDocument leadDoc, 
   FormRecognitionAttributes masterAttributes, 
   FormPages formFields 
)

public void processForm( 
   LEADDocument leadDoc, 
   FormRecognitionAttributes masterAttributes, 
   FormPages formFields 
);

public:  
   void ProcessForm( 
      LEADDocument^ leadDoc, 
      FormRecognitionAttributes^ masterAttributes, 
      FormPages^ formFields 
   )

def ProcessForm(self,leadDoc,masterAttributes,formFields):

Parameters

leadDoc

The LEADDocument containing the recognized document pages.

masterAttributes

The Master Form attributes of the form type.

formFields

The fields to be processed for the Master Form of the form type.

Remarks

This method allows form processing at a later state or on another machine without the need to recreate the recognition result object.

The document alignment is calculated from the recognition results.
