Not really. I designed the vertical support in Pango, but I have no clue about the win32 backend. > Does anyone know where I > would need to start hacking to add support?

Fix this function: pango_win32_face_get_face_name() to also unset gravity. I find that function gross BTW. > How does gravity actually work in Pango internally? Do the font files on > disk have to provide some extra hints? Not really. The backend needs to load a vertical variant of the font though. IIRC, on Windows, prepending an '@' character to the beginning of the family name loads the vertical-metrics variant. So you may want to try that. There, of course, may be other changes needed. Just search for gravity around the fontconfig backend and see what's going on... > Any help would be appreciated, and thanks beforehand... behdad _______________________________________________ gtk-i18n-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtk-i18n-list
