ProcessPage(RasterImage,Int32,AutoFormsRecognizePageResult) Method

Summary

Performs field processing on the recognized page image.

Syntax

C++

public Leadtools.Forms.Processing.FormPage ProcessPage(  
   Leadtools.RasterImage page, 
   int pageNumber, 
   Leadtools.Forms.Auto.AutoFormsRecognizePageResult pageResult 
)

Public Overloads Function ProcessPage( _ 
   ByVal page As Leadtools.RasterImage, _ 
   ByVal pageNumber As Integer, _ 
   ByVal pageResult As Leadtools.Forms.Auto.AutoFormsRecognizePageResult _ 
) As Leadtools.Forms.Processing.FormPage

public: 
Leadtools.Forms.Processing.FormPage^ ProcessPage(  
   Leadtools.RasterImage^ page, 
   int pageNumber, 
   Leadtools.Forms.Auto.AutoFormsRecognizePageResult^ pageResult 
)

Parameters

page
The recognized page image.

pageNumber
1-based index of the in page.

pageResult
The recognition result of the page that is returned by RecognizePage(RasterImage,Int32,List<IMasterFormsCategory>).

Return Value

The processed fields of 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 pageResult.

The page must have all form pages.
