Summary

Performs field processing on the recognized form image.

Syntax

C++/CLI

Java

Python

public FormPages ProcessForm( 
   Stream stream, 
   AutoFormsRecognizeFormResult formResult 
)

public FormPages processForm( 
   ILeadStream,  
   AutoFormsRecognizeFormResult 
);

public: 
FormPages^ ProcessForm(  
   Stream^ stream, 
   AutoFormsRecognizeFormResult^ formResult 
)

def ProcessForm(self,stream,formResult):

Parameters

stream
A System.IO.Stream containing the unknown form image data.

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

Return Value

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

Remarks

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

The stream should have all form pages.

The form alignment is calculated from the recognition results.
