canvas as background?

Tue Jan 23 10:07:06 UTC 2007

hi everybody,

i got a canvas, which i want to use as background. there a several coloured circles on it.

now i want to have something like a foreground... i want to draw something on it, clear the foreground, draw and clear in a loop.

the background should not be affected by this "loop". i tried to simply use one canvas for background, one for foreground, but this didn't work out...

can someone tell me how to achieve this?  

thanks a lot
