Parameters

leadDoc

The LEADDocument containing the recognized document pages.

pageNumber

The index of the recognized page within the LEADDocument object.

formResult

The recognition result of the form that is returned by RecognizeForm(LEADDocument,List<IMasterFormsCategory>).

formPageNumber

The form page from recognition results to be processed.
