Summary

Performs field processing on the recognized document pages within LEADDocument.

Syntax

C++/CLI

Java

Python

public FormPages ProcessForm( 
   LEADDocument leadDoc, 
   AutoFormsRecognizeFormResult formResult 
)

public FormPages processForm( 
   LEADDocument,  
   AutoFormsRecognizeFormResult 
);

public:  
   FormPages^ ProcessForm( 
      LEADDocument^ leadDoc, 
      AutoFormsRecognizeFormResult^ formResult 
   )

def ProcessForm(self,leadDoc,formResult):

Parameters

leadDoc

The LEADDocument containing the recognized document pages.

formResult

The form recognition result that has been returned by RecognizeForm(LEADDocument, List<IMasterFormsCategory>).

Return Value

The processed fields, if the Master Form has fields; otherwise null.

Remarks

This method processes the recognized form fields. The Master Form fields are obtained by calling IMasterForm.ReadFields of the AutoFormsRecognizeFormResult.MasterForm.

The document alignment is calculated from the recognition results.
