Re: CGContextReplacePathWithStrokedPath problem?

Never mind, I was doing something wrong - it does honour all of those settings ;-) Apologies for doubting Quartz's engineers! (BTW, an aside: since Quartz has the ability to do this sort of bezier curve fitting, how about exposing more of it in the API? It would be great to be able to "unfl
