Message-ID: <996@h.cs.wvu.wvnet.edu> Date: 12 Nov 90 21:26:50 GMT Sender: news@cs.wvu.wvnet.edu Lines: 8 I would like to know more about the implementation of regions on the Macintosh. I remember someone mentioning the use of "inversion points" in the Macintosh implementation. What exactly is the theory behind "inversion points"? Any references are welcome. But specifically I would like details on how to access the region description given a region handle so that I can manipulate the region eg: rotation, inversion, etc.
