Hello Huub, I changed some things in SWFShapeMaker.cpp in my SVG patch. A quick test showed that the bottom values of 'o' and 'e' in Vera.ttf are almost equal with the patch applied. You can try to apply the patch and check if it works for you. Although I'm not sure if the bounding box calculation in my version is correct, because I haven't tested if the values it produces are accurate.
You can download the patch at: http://osflash.org/pipermail/swfmill_osflash.org/2007-May/001274.html Ralf > Hello > > I used swfmill to generate a swf library containing just a few glyphs from a > font.
