ProcessPage(Stream,Int32,AutoFormsRecognizeFormResult,Int32) Method

Example 





A System.IO.Stream containing the the recognized page image data.
1-based index of the in stream.
The recognition result of the form that is returned by RecognizeForm(RasterImage,List<IMasterFormsCategory>).
The form page number to be processed.
Performs field processing on the recognized page image.
Syntax
public FormPage ProcessPage( 
   Stream stream,
   int pageNumber,
   AutoFormsRecognizeFormResult formResult,
   int formPageNumber
)
'Declaration

'Usage
 
Dim instance As AutoFormsEngine
Dim stream As Stream
Dim pageNumber As Integer
Dim formResult As AutoFormsRecognizeFormResult
Dim formPageNumber As Integer
Dim value As FormPage
 
value = instance.ProcessPage(stream, pageNumber, formResult, formPageNumber)

   stream ,
   pageNumber ,
   formResult ,
   formPageNumber 
)

Parameters

stream
A System.IO.Stream containing the the recognized page image data.
pageNumber
1-based index of the in stream.
formResult
The recognition result of the form that is returned by RecognizeForm(RasterImage,List<IMasterFormsCategory>).
formPageNumber
The form page number to be processed.

Return Value

The processed fields of the 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 formResult.

The stream must have all form pages.
