- fileName
- A System.String containing the the unknown form image file.
- masterAttributes
- The Master Form attributes of the form type.
- formFields
- The fields to be processed for the Master Form of the form type.

This method processes the recognized form fields. The Master Form fields are obtained by calling IMasterForm.ReadFields of the AutoFormsRecognizeFormResult.MasterForm.
The fileName should have all form pages.
This method is useful because it allows you to do the form processing later on or on another machine without the need to recreate the recognition result object
The form alignment is calculated internally, so providing the recognition results will speed the alignment calculation process.
