ProcessForm(Uri,AutoFormsRecognizeFormResult) Method

Summary

Performs field processing on the recognized form image.

Syntax

C++

public FormPages ProcessForm( 
   Uri url, 
   AutoFormsRecognizeFormResult formResult 
)

  
Public Overloads Function ProcessForm( _ 
   ByVal url As Uri, _ 
   ByVal formResult As Leadtools.Forms.Auto.AutoFormsRecognizeFormResult _ 
) As Leadtools.Forms.Processing.FormPages

public: 
Leadtools.Forms.Processing.FormPages^ ProcessForm(  
   Uri^ url, 
   Leadtools.Forms.Auto.AutoFormsRecognizeFormResult^ formResult 
)

Parameters

url
A System.Uri 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 url should have all form pages.

The form alignment is calculated from the recognition results.
