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.
