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

Parameters

page
The recognized page image.

pageNumber
1-based index of the in page.

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 page must have all form pages.
