Looking more, looks like both TrueType and Type 1 / CFF use non-zero winding rule. (I'm relieved!) TrueType *recommends* that the outer-most outline be clockwise (solid-to-the-right / fill-right), while Type 1 / CFF recommend the other way around. But AFAIU, both are just non-zero at the end, and fonts do violate that recommendations quite frequently in the wild. -- behdad http://behdad.org/ _______________________________________________ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
