Java
C++

public FormPage ProcessPage( 
   Stream stream,
   int pageNumber,
   AutoFormsRecognizePageResult pageResult
)

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

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

public:
FormPage^ ProcessPage( 
   Stream^ stream,
   int pageNumber,
   AutoFormsRecognizePageResult^ pageResult
)

Parameters

stream: A System.IO.Stream containing the the recognized page image date.
pageNumber: 1-based index of the in stream.
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 stream must have all form pages.
