While fontconfig is usually configured to ignore bitmap fonts anyway, I think you should enforce that by putting this call here: FcPatternAddBool(fc_pattern, FC_SCALABLE, FcTrue); > FcConfigSubstitute(0, fc_pattern, FcMatchPattern); > FcDefaultSubstitute(fc_pattern); > fc_pattern = FcFontMatch(0, fc_pattern, 0); > FcChar8 *s; > FcPatternGetString(fc_pattern, FC_FILE, 0, &s); > fprintf(stderr, "font '%s'\n", s);//XXX > free(fc_pattern); Use FcPatternDestroy(fc_pattern) instead, using free() here causes an error for me. > FcFini(); > > it prints > > font '/usr/share/fonts/truetype/arial.ttf' > > which looks good.

Hmm... AFAIK it is scalable and freetype can use it.

Gathering from http://www.xemacs.org/Documentation/packages/html/fontconfig_3.html , it can be done with something like this: // what info is requested: FcObjectSet *os = FcObjectSetBuild(FC_FAMILY, NULL); // what fonts are requested: FcPattern *pat = FcPatternBuild(NULL, FC_SCALABLE, FcTypeBool, FcTrue, NULL); FcFontSet* fontset = FcFontList(0, pat, os); FcObjectSetDestroy(os); FcPatternDestroy(pat); for (int i = 0; i < fontset->nfont ; i++) { FcChar8 *t; FcPatternGetString(fontset->fonts[i], FC_FAMILY, 0, &t); fprintf(stderr, "font '%s'\n", t); } FcFontSetDestroy(fontset); Note that I am only googling this info, I don't really know about fontconfig myself ;) -- Anssi Hannula _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
