) 

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.

In a case that the number of pages in unKnown of the Form, such as scanner loaded with different forms, it is preferable to use ComparePage(FormRecognitionAttributes,Int32,FormRecognitionAttributes,Int32) to compare it with the first page of each Master Form then use GetFormProperties to get the number of pages of the Master Form then update your Form attributes with the required pages if needed for processing.

In order to recognize a Form, the Form attribute object must be compared with all of the Master Form attribute objects 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.
