ProcessForm(Stream,AutoFormsRecognizeFormResult) Method

public FormPages ProcessForm( 
   Stream stream,
   AutoFormsRecognizeFormResult formResult
)

public:
FormPages^ ProcessForm( 
   Stream^ stream,
   AutoFormsRecognizeFormResult^ formResult
)

'Declaration
 
Public Overloads Function ProcessForm( _
   ByVal stream As Stream, _
   ByVal formResult As AutoFormsRecognizeFormResult _
) As FormPages

'Usage
 
Dim instance As AutoFormsEngine
Dim stream As Stream
Dim formResult As AutoFormsRecognizeFormResult
Dim value As FormPages
 
value = instance.ProcessForm(stream, formResult)

Parameters

stream: A System.IO.Stream containing the 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.

This method processes the recognized form fields. The Master Form fields are obtained by calling IMasterForm.ReadFields of the AutoFormsRecognizeFormResult.MasterForm.

The stream should have all form pages.

The form alignment is calculated from the recognition results.
