dr geep: I'm going to partially take back my statement in my previous post. I can't find one tool the does exactly what you are looking for in Canvas, acting like out-spreading water from one pixel color. Canvas has a tool, called the blur tool. You can set the pixel diameter affected by selecting a 'brush' size, you can call 'pressure' into play if you have a pressure sensitive imput device. If you hold down the mouse, the tool will continue to 'blur', in place, over time, until you let go or it reaches a user-controled 'fade diameter'. I looks like water spreading, but does not spread the color of one pixel outwards. I use it as a 'traveling anti-alias tool' by blowing up to as much as 3200% and dragging/painting along the interface between two contrasting boundaries. It melts them together beautifully. ::::: Opera :::::
