Is there any method to get a pixel from the canvas? I can draw a pixel
(painfully by using either
line or rectangle, same storage anyway) but can I sample a pixel ?

I recall vaguely that Java could probably do it, how about Qt4?
(haven't done anything in Qt4
and haven't coded Java for years.)

Thank you.

Tee Shift.
