The ZGF reader extracts features from a file one at a time, and passes them on to the rest of the FME for further processing. The reader finishes when it reaches the end of the file.
Each feature returned by the ZGF reader has its FME feature type set to one of the following: zgf_polyline, zgf_marker, zgf_text, zgf_clipwindow, zgf_polygon or zgf_applicationdata.
