Hi, Folks- I think David is right, a mask is the correct thing to do here, but it's not very intuitive.
It does seem strange that there is no easy way to reverse the clip-path. Last week, I filed a feature request to add it in SVG 2; that doesn't help right now, but it will make things easier in the future. http://www.w3.org/Graphics/SVG/WG/track/issues/2354 Regards- -Doug ddailey wrote (on 7/31/10 8:42 PM): > Interesting question.
