Gotcha. Perhaps in the future we can push that implementation-necessity down to the porting layer, rather than forcing that detail to be in the portable layer.
Again, I'm just looking for a way to have round-rects look antialiased (and therefore not clipped). On 1/9/07, David Hyatt <[EMAIL PROTECTED]> wrote:
The problem I ran into with box-shadow is that the shadow cannot show up anywhere within the contents of the box. It has to be clipped out. Maybe there's a clever way to get the same result that I'm not thinking of though. Note that CG draws shadows in response to other drawing operations (in this case a fill). As far as I can tell with CG, I can't just draw a shadow in a vacuum. It has to be implicitly cast by some other drawing operation. So I'm basically doing a fill, which casts the shadow, and then ensuring that the entire fill is clipped out so that it isn't seen. dave On Jan 9, 2007, at 7:04 AM, Mike Reed wrote: > Do we need to use clips for round-rects?
