just a short remark, which I observed a while ago and always missed to report.

(At a display resolution of e.g. 800x600x32,) The following looks odd, because there seem to be gaps in the edge-drawing around the Circle()-object. I guess, it should (and can) look better than this with improved antialias? At least, my tests on linux with some 800x600-eps graphics with circles of the same size looks a lot smoother.

Code: Select all

Local r=33

SetFormStyle(#NORMAL)
SetFormStyle(#ANTIALIAS)
SetFormStyle(#EDGE, #BLACK, 1)
SetFormStyle(#SHADOW, $99939393, 5, 3)
SetFillStyle(#FILLCOLOR)

Circle(x, y, r, $F0F8FF)

thanks, Tom

Yes, this is a known problem because Hollywood's circle drawing is still line based. Support for real curves is planned, though.
