ProcessForm(Stream,FormRecognitionAttributes,FormPages) Method

Summary

Performs field processing on the recognized form image.

Syntax

C++/CLI

Java

Python

public void ProcessForm( 
   Stream stream, 
   FormRecognitionAttributes masterAttributes, 
   FormPages formFields 
)

public void processForm( 
   ILeadStream,  
   FormRecognitionAttributes,  
   FormPages 
);

public: 
void ProcessForm(  
   Stream^ stream, 
   FormRecognitionAttributes^ masterAttributes, 
   FormPages^ formFields 
)

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

Parameters

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

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 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.

This method is useful because it allows you to do the form processing later on or on another machine without the need to recreate the recognition result object

The form alignment is calculated internally, so providing the recognition results will speed the alignment calculation process.
