Python

public FormPage ProcessPage( 
   Stream stream, 
   int pageNumber, 
   AutoFormsRecognizeFormResult formResult, 
   int formPageNumber 
)

public FormPage processPage( 
   ILeadStream,  
   int,  
   AutoFormsRecognizeFormResult,  
   int 
);

public: 
FormPage^ ProcessPage(  
   Stream^ stream, 
   int pageNumber, 
   AutoFormsRecognizeFormResult^ formResult, 
   int formPageNumber 
)

def ProcessPage(self,stream,pageNumber,formResult,formPageNumber):

Parameters

stream
A System.IO.Stream containing 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.
