Syntax

C++/CLI

Java

Python

public FormPage ProcessPage( 
   RasterImage page, 
   int pageNumber, 
   AutoFormsRecognizeFormResult formResult, 
   int formPageNumber 
)

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

public: 
FormPage^ ProcessPage(  
   RasterImage^ page, 
   int pageNumber, 
   AutoFormsRecognizeFormResult^ formResult, 
   int formPageNumber 
)

def ProcessPage(self,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
