To embed TrueType and OpenType font files, you need to extract the font metrics from the font files and build the required tables using the utility TTF2UFM. TTF2UFM is a modified version of Mark Heath's TTF 2 PT1 converter (http://ttf2pt1.sourceforge.net/) by Steven Wittens <email@example.com> (http://www.acko.net/blog/ufpdf). That version has been further modified by Ulrich Telle for use with the wxWidgets component wxPdfDocument. Following changes where made: 1) Generated AFM files contain the glyph number for each character. 2) Generated UFM files contain the bounding box for each character. 3) OpenType support has been activated for the Windows binary, and the generated AFM/UFM files contain the associated original Unicode codes for each character.
