Just creating a stub page.. but eventually we will need a text API.

Likely it should be mostly the same as the A4 one.

Contents

Structures

ALLEGRO_FONT

Internally, this will have a vtable, and font-driver-specific data. E.g. A Freetype driver probably will wrap around Freetype's structures. If it's targetting OpenGL, likely it also has a texture cache and stuff like that.

A bitmap-font driver just will have a big list of bitmaps. 

struct ALLEGRO_FONT

Font loading

al_load_font 

ALLEGRO_FONT *al_load_font(char const *filename, float size, int flags);

Not really sure yet what is needed..

Text output 

void al_draw_text(ALLEGRO_FONT *font, int x, int y, int flags, ALLEGRO_COLOR *color, char const *text);

void al_printf(ALLEGRO_FONT *font, int x, int y, int flags, ALLEGRO_COLOR *color, char const *format, ...);


  • Parameter order needs to be fixed yet.
  • Maybe the font to use should be a state?
