Remarks:

This enumerates the possible content types of the zones from the Engine's perspective. Each zone must have one of the filling methods listed here. It can be done by specifying the FillingMethod field of the zones defined on the image.

Each zone needs to be associated with a enumIGRecRecognitionModule (RM) and a enumIGRecFillingMethod (FM). This is needed because some RMs support more than one FM, and some FMs are accepted by more than one RM. It is important to ensure that the RM-FM pair is suitable (see documentation for enumIGRecRecognitionModule).
