CompareExtendedForm Method

public FormRecognitionResult CompareExtendedForm( 
   FormRecognitionAttributes masterAttributes,
   FormRecognitionAttributes formAttributes,
   FormProgressCallback formCallback,
   PageProgressCallback pageCallback
)

'Declaration
 
Public Function CompareExtendedForm( _
   ByVal masterAttributes As FormRecognitionAttributes, _
   ByVal formAttributes As FormRecognitionAttributes, _
   ByVal formCallback As FormProgressCallback, _
   ByVal pageCallback As PageProgressCallback _
) As FormRecognitionResult

'Usage
 
Dim instance As FormRecognitionEngine
Dim masterAttributes As FormRecognitionAttributes
Dim formAttributes As FormRecognitionAttributes
Dim formCallback As FormProgressCallback
Dim pageCallback As PageProgressCallback
Dim value As FormRecognitionResult
 
value = instance.CompareExtendedForm(masterAttributes, formAttributes, formCallback, pageCallback)

public:
FormRecognitionResult^ CompareExtendedForm( 
   FormRecognitionAttributes^ masterAttributes,
   FormRecognitionAttributes^ formAttributes,
   FormProgressCallback^ formCallback,
   PageProgressCallback^ pageCallback
) 

Parameters

masterAttributes

The Master Form attribute object.

formAttributes

The Form attribute object.

formCallback

Status about the progress of the comparison at the form level (i.e. page by page). Set it to null to ignore the progress.

pageCallback

Provides status on the progress of the comparison at the page level. Set it to null to ignore the progress.

This function should be used To Compare Form with Master forms that have invoice (TableFormField).

In order to recognize a Form, the Form attribute object must be compared with all of the Master Form attribute objects that have incoive (TableFormField),representing different types of form templates. The Form's type is that Master Form attribute object that generated the highest confidence value. If the highest confidence value is very low that means the Form is not one the types of the Master Forms (i.e. the type of this Form is not defined in the Master Form set)

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

This example compares a Master Form with a Form.
