Hi Alan, I just committed the changes: the individual curves are now drawn both as polylines and as filled curves. While I do not think it is all that well-defined (some of the curves are very convoluted, in the colloquial sense, not the geometrical one), it does give some interesting results. The deltoid for instance, a non-intersecting curve, is NOT filled by the wingcc device. It is for the PostScript output. The next one in line, a curve like the deltoid but with three loops in stead of cusps gets partly filled - the loops are.
I assume you will see the same sort of things with wine. I have not tried the gradients yet. That is a next step, later this week. Regards, Arjen On 2010-12-30 20:01, Alan W.
