Syntax
C#
VB
C++
  
Public Overloads Function ProcessPage( _ 
   ByVal fileName As String, _ 
   ByVal pageNumber As Integer, _ 
   ByVal pageResult As AutoFormsRecognizePageResult _ 
) As FormPage 
public: 
FormPage^ ProcessPage(  
   String^ fileName, 
   int pageNumber, 
   AutoFormsRecognizePageResult^ pageResult 
)  

Parameters

fileName
A System.String containing the recognized page image file.

pageNumber
1-based index of the in fileName.

pageResult
The recognition result of the page that is returned by RecognizePage(RasterImage,Int32,List<IMasterFormsCategory>).

Return Value

The processed fields of the page if they exist, otherwise it returns null.

Remarks

If the specified page does not have processing fields, it returns null.

The alignment to the page is calculated internally from the pageResult.

The fileName must have all form pages.
