man load_font () - Loads a font from a file. Allegro game programming library.
NAME
load_font - Loads a font from a file. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
FONT *load_font(const char *filename, RGB *pal, void *param);
DESCRIPTION
Loads a font from a file. At present, this supports loading fonts from a GRX format .fnt file, a 8x8 or 8x16 BIOS format .fnt file, a datafile or any bitmap format that can be loaded by load_bitmap().
If the font contains palette information, then the palette is returned in the second parameter, which should be an array of 256 RGB structures (a PALETTE). The pal argument may be NULL. In this case, the palette data, if present, is simply not returned.
The third parameter can be used to pass specific information to a custom loader routine. Normally, you can just leave this as NULL. Note that another way of loading fonts is embedding them into a datafile and using the datafile related functions.
Example:
FONT *myfont;
PALETTE palette;
...
myfont = load_font("my_font.pcx", palette, NULL);
if (!myfont)
abort_on_error("Couldn't load font!");
...
textout_centre_ex(screen, myfont, "This is my own pretty font!",
SCREEN_W / 2, SCREEN_H / 2, white, black);
...
destroy_font(bmp);
RETURN VALUE
Returns a pointer to the font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks.
