lcd madness


    Jun 29 2006 | 1:43 pm
    i'm loosing my mind since a few hours with lcd : how do we erase one
    shape without erasing the other shapes around / under ???? What is the
    needed penmode ? is it really penmode i would like to use ?

      haha, this is exatcly what i was thinking when i
      started using lcd.
      when i also had no success trying this using sprites
      or zones i simply no longer made things in lcd which
      require to delete one of three figures. :)
      lets lean back and wait for a better answer.

      merci Camille, i've found a workaround : keeping trace of everything
      drawn before, then redraw when needed ;-)

      That'll work (and it's what I often do for JSUI components), but the
      point of sprites is to do this for you...

      I know it's an ancient technology, but the graphics object _does_
      support sprites. In my (subjective) experience it makes less
      processing demands than lcd or Jitter.
      Caveat: I have no experience with how it behaves on Windows.
      Last year I revived an old external for drawing arbitrary polygons in
      the graphics window, did the port to Carbon in some number of
      minutes. It worked great. If someone needed it and, assuming all the
      QuickDraw is supported in Windows, I expect I could get it running
      there, too.
      New technologies are great, but does that mean you *have* to throw
      everything old out? I hear Windows folks still run .BAT files
      sometimes...

      To quote a comment I saw on Slashdot recently: son, I have a .emacs
      that's older than you and some of your friends.
