Right now I'm testing fnt_new( <INT file> , <INT graph>, <INT charset> , <INT width> , <INT height> , <INT first> , <INT last> , <INT flags> ) for documentation and I'm having bad luck. I try to use bitmaps from an fpg file, but When I write a text, it doesn't display. I a tried a couple of different things but I'm puzzled. :(

What is a bit unclear to me, is the graph from an array? and the "first" and "last" parameters. Do I have to call this function in a loop or just once? The C code in libfont.c is a bit too hard for me.

A test sample would be helpfull. I attached two fpg files, the first one, has 152 characters in it, and the second one has 36 characters. The width and height are not constant. (Is that perhaps a couse???)

Bottom line: have I forgotten something?


This is my (not working) code ;D :


IMPORT "mod_say";
IMPORT "mod_debug";
IMPORT "mod_key";
IMPORT "mod_text";
IMPORT "mod_map";
IMPORT "mod_path";
IMPORT "mod_video";
IMPORT "mod_wm";
IMPORT "mod_draw";
IMPORT "mod_screen";

font have charmaps... I have pending review this.
