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.
