Leadtools.Forms.Recognition Namespace > FormRecognitionEngine Class > ComparePage Method : ComparePage(FormRecognitionAttributes,Int32,FormRecognitionAttributes,Int32,PageProgressCallback) Method



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.
callback
Optional callback to show operation progress.

The ComparePage(FormRecognitionAttributes,Int32,FormRecognitionAttributes,Int32,PageProgressCallback) Method is available as an add-on to the LEADTOOLS Document and Medical Imaging toolkits.

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.
callback
Optional callback to show operation progress.
Returns a PageRecognitionResult object that describes how close the specified Form page is in comparison to the specified Master Form page.

Syntax

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

Visual Basic (Usage)Copy Code
Dim instance As FormRecognitionEngine
Dim masterAttributes As FormRecognitionAttributes
Dim masterPageNumber As Integer
Dim formAttributes As FormRecognitionAttributes
Dim formPageNumber As Integer
Dim callback As PageProgressCallback
Dim value As PageRecognitionResult
 
value = instance.ComparePage(masterAttributes, masterPageNumber, formAttributes, formPageNumber, callback)

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.
callback
Optional callback to show operation progress.

Example

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

This example adds a page to the form

Visual BasicCopy Code
'''This method compares the first page of a Form to the first page of a Master Form.
Private Function CompareFirstPage(ByVal recognitionEngine As FormRecognitionEngine, ByVal master As FormRecognitionAttributes, ByVal form As FormRecognitionAttributes) As FormRecognitionResult
   Dim resultPage As PageRecognitionResult = recognitionEngine.ComparePage(master, 1, form, 1)
   Dim result As FormRecognitionResult = New FormRecognitionResult()
   result.Confidence = resultPage.Confidence
   result.LargestConfidencePageNumber = 1
   result.PageResults.Add(resultPage)
   result.Reason = FormRecognitionReason.Success
   Return result
End Function
C#Copy Code
///This method compares the first page of a Form to the first page of a Master Form.
FormRecognitionResult CompareFirstPage(FormRecognitionEngine recognitionEngine, FormRecognitionAttributes master, FormRecognitionAttributes form)
{
   PageRecognitionResult resultPage = recognitionEngine.ComparePage(master, 1, form, 1);
   FormRecognitionResult result = new FormRecognitionResult();
   result.Confidence = resultPage.Confidence;
   result.LargestConfidencePageNumber = 1;
   result.PageResults.Add(resultPage);
   result.Reason = FormRecognitionReason.Success;
   return result;
}

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 since the Master Form attribute object does not have the text features the Form has.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
