| Using non-ttf fonts or default text in Allegro 5 |

I only need basic text output in a low resolution, 4-bit display. I gather from my readings that Allegro previously had a default font. Does it still? Assuming I would have to load my own, I find vgasys.fon (common on Windows systems) to be just fine. Note it is not a TTF. If I have to resort to this moving forward, how could I use this minimal font? Utilizing TTF routines not only seems unnecessary, it also does a terrible job at display a .FON. I'm assuming because it is not supported. |

cantide5ga said: Does it still? No. You can load bitmap fonts, however using al_load_bitmap_font. There is a bitmap font that you can find in the examples/data directory. I think it's called a4font.tga or something. "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |

Correct me if I am wrong, but I think you are referring to a4_font.tga. Thanks for pointing me in the right direction. EDIT Assertion fail: font, file allegro-5.0.x\addons\font\text.c, line 73 Generic example of what I am doing: 1#include <stdio.h>
2#include <allegro5/allegro.h>
3#include <allegro5/allegro_font.h>

5int main(int argc, char **argv)

10 fprintf(stderr, "failed to initialize allegro!\n");
11 return -1;

14 display = al_create_display(320, 200);
15 if(!display) {
16 fprintf(stderr, "failed to create display!\n");

24 al_clear_to_color(al_map_rgb(0,0,0));
25 al_draw_text(font, al_map_rgb(255,255,255), 0,0,0, "");

You need the image addon to load bitmap fonts. See ex_font.c
