   int pageNumber,
   AutoFormsRecognizePageResult pageResult
)

'Declaration
 
Public Overloads Function ProcessPage( _
   ByVal page As RasterImage, _
   ByVal pageNumber As Integer, _
   ByVal pageResult As AutoFormsRecognizePageResult _
) As FormPage

'Usage
 
Dim instance As AutoFormsEngine
Dim page As RasterImage
Dim pageNumber As Integer
Dim pageResult As AutoFormsRecognizePageResult
Dim value As FormPage
 
value = instance.ProcessPage(page, pageNumber, pageResult)

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 the page if they exist, otherwise it returns null.

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.
