This is how Pango maps them: static int pango_fc_convert_weight_to_fc (PangoWeight pango_weight) { if (pango_weight <= (PANGO_WEIGHT_THIN + PANGO_WEIGHT_ULTRALIGHT) / 2) return FC_WEIGHT_THIN; else if (pango_weight <= (PANGO_WEIGHT_ULTRALIGHT + PANGO_WEIGHT_LIGHT) / 2) return FC_WEIGHT_ULTRALIGHT; else if (pango_weight <= (PANGO_WEIGHT_LIGHT + PANGO_WEIGHT_BOOK) / 2) return FC_WEIGHT_LIGHT; else if (pango_weight <= (PANGO_WEIGHT_BOOK + PANGO_WEIGHT_NORMAL) / 2) return FC_WEIGHT_BOOK; else if (pango_weight <= (PANGO_WEIGHT_NORMAL + PANGO_WEIGHT_MEDIUM) / 2) return FC_WEIGHT_NORMAL; else if (pango_weight <= (PANGO_WEIGHT_MEDIUM + PANGO_WEIGHT_SEMIBOLD) / 2) return FC_WEIGHT_MEDIUM; else if (pango_weight <= (PANGO_WEIGHT_SEMIBOLD + PANGO_WEIGHT_BOLD) / 2) return FC_WEIGHT_DEMIBOLD; else if (pango_weight <= (PANGO_WEIGHT_BOLD + PANGO_WEIGHT_ULTRABOLD) / 2) return FC_WEIGHT_BOLD; else if (pango_weight <= (PANGO_WEIGHT_ULTRABOLD + PANGO_WEIGHT_HEAVY) / 2) return FC_WEIGHT_ULTRABOLD; else if (pango_weight <= (PANGO_WEIGHT_HEAVY + PANGO_WEIGHT_ULTRAHEAVY) / 2) return FC_WEIGHT_BLACK; else return FC_WEIGHT_EXTRABLACK; } where: typedef enum { PANGO_WEIGHT_THIN = 100, PANGO_WEIGHT_ULTRALIGHT = 200, PANGO_WEIGHT_LIGHT = 300, PANGO_WEIGHT_BOOK = 380, PANGO_WEIGHT_NORMAL = 400, PANGO_WEIGHT_MEDIUM = 500, PANGO_WEIGHT_SEMIBOLD = 600, PANGO_WEIGHT_BOLD = 700, PANGO_WEIGHT_ULTRABOLD = 800, PANGO_WEIGHT_HEAVY = 900, PANGO_WEIGHT_ULTRAHEAVY = 1000 } PangoWeight; behdad > TIA _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/fontconfig
