ComparePage(FormRecognitionAttributes,int,FormRecognitionAttributes,int) Method

Summary

Returns a PageRecognitionResult object that describes how close the specified Form page is in comparison to the specified Master Form page.

Syntax

C++

Java

public PageRecognitionResult ComparePage( 
   FormRecognitionAttributes masterAttributes, 
   int masterPageNumber, 
   FormRecognitionAttributes formAttributes, 
   int formPageNumber 
)

  
Public Overloads Function ComparePage( _ 
   ByVal masterAttributes As FormRecognitionAttributes, _ 
   ByVal masterPageNumber As Integer, _ 
   ByVal formAttributes As FormRecognitionAttributes, _ 
   ByVal formPageNumber As Integer _ 
) As PageRecognitionResult

public PageRecognitionResult comparePage( 
   FormRecognitionAttributes masterAttributes, 
   int masterPageNumber, 
   FormRecognitionAttributes formAttributes, 
   int formPageNumber 
);

public: 
PageRecognitionResult^ ComparePage(  
   FormRecognitionAttributes^ masterAttributes, 
   int masterPageNumber, 
   FormRecognitionAttributes^ formAttributes, 
   int formPageNumber 
)

Parameters

masterAttributes
The attributes of the Master Form.

masterPageNumber
The reference Master Form page. The page number is a 1-based index.

formAttributes
The Form attributes object.

formPageNumber
The page of the form being aligned. The page number is a 1-based index.

Remarks

Comparisons should be made between two attribute sets that have been generated using the Default Manager Objects. For example, if the Master Form attribute object was generated using the BarcodeManager and the Form attribute object was generated using the OcrManager, then the Form will not be recognized (the Master Form attribute object would not have the text features of the Form object).

Example

For a complete example on using form recognition and processing, refer to the FormRecognitionEngine example.
