When a zone recognition module setting is IG_REC_RM_AUTO, set either by default or explicitly, the recognition engine takes care of recognition module selection for any filling method. When setting specific values for filling methods and recognition modules, it is the programmer's responsibility to specify a valid recognition module-filling method pair. Any incorrectly set zone will have no recognition result. The following table shows which modules are considered by the automatic recognition module selection, called up by the IG_REC_RM_AUTO value. The order of the recognition modules in the second column shows the priority order for the automatic recognition module selection.
