<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><DIV>I was fascinated by the discussion this last week of subtractive clipping. Cool stuff. So much so, that I wanted to use something like it for an example in my StS presentation next week.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>My goal is to draw an image with a "cheese grater" effect. That is with holes punched in it where the background shows through. But I can't seem to make it work. No matter what I do, I get the opposite. A bunch circles showing the image.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>What I have is a highlevel function that builds a clockwise rectangle with rounded corners and sets that as the clip. That's the "outer bounds". Then in my specific example routine, I path a bunch of circles with (newSubPath, arc_negative(2PI), close) sequences. And then a clip again. Is the problem that the outer bounds and all of these sub circles needed to part of the same path at the time I send clip?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I'll see if I can't try to concoct that and cross my fingers.</DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>--</DIV><DIV>Travis Griggs</DIV><DIV>Objologist</DIV><DIV>"There are a thousand hacking at the branches of evil to one who is striking at the root" - Henry David Thoreau</DIV><BR class="Apple-interchange-newline"></SPAN></SPAN> </DIV><BR></BODY></HTML>
