I already saw that assertion when I wrote my last reply and was surprised that I (so I thought) had added it.

Can't tell, but I fear glyphs are even more special because they apparently use different filling rules (non-zero vs. even-odd). That is documented nowhere (except our source code) but without this distinction some fonts are not displayed correctly. The filling rule defines how crossing edges should be handled and thus influences which pixels are filled. >> <ot> >> However it would be great to have multi-layered glyphs with >> complex fills (like normal shapes) in Flash. ;) >> </ot> s> This is free software, nothing prevents you from doing it! :) I thought we want to be compatible ;) Udo _______________________________________________ Gnash-dev mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gnash-dev
