I hope someone can answer this. I'm writing a 'space invaders' game using only images created by canvas (to use as a demo for my work) and I want to be able to clear different canvas images on the same screen area by rendering them in different 'contexts' and using different 'contextX.clearRect(x,y,x,y)' commands.

Is this possible? At the moment all that happens is the 'contextX.clearRect(x,y,x,y)' clears EVERY context in that given rectangle!!!!!!!!

Hi there,

This forum is just for RGraph - not general canvas issues.
