Example 





The recognized page image.

Syntax
'Declaration
 
Public Overloads Function ProcessPage( _
   ByVal page As RasterImage, _
   ByVal pageNumber As Integer, _
   ByVal formResult As AutoFormsRecognizeFormResult, _
   ByVal formPageNumber As Integer _
) As FormPage
'Usage
 
Dim instance As AutoFormsEngine
Dim page As RasterImage
Dim pageNumber As Integer
Dim formResult As AutoFormsRecognizeFormResult
Dim formPageNumber As Integer
Dim value As FormPage
 
value = instance.ProcessPage(page, pageNumber, formResult, formPageNumber)
 function Leadtools.Forms.Auto.AutoFormsEngine.ProcessPage(RasterImage,Int32,AutoFormsRecognizeFormResult,Int32)( 
   page ,
   pageNumber ,
   formResult ,
   formPageNumber 
)

Parameters

page
The recognized page image.
pageNumber
1-based index of the in page.
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 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 page must have all form pages.
