register_font_file_type(3alleg4)				  Allegro manual				  register_font_file_type(3alleg4)

register_font_file_type - Register a new font loading function. Allegro game programming library. SYNOPSIS
#include <allegro.h> void register_font_file_type(const char *ext, FONT *(*load)(const char *filename, RGB *pal, void *param)); DESCRIPTION
Informs the load_font() functions of a new file type, providing a routine to read fonts in this format. The function you supply must follow the following prototype: FONT *load_my_font(const char *filename, RGB *pal, void *param) { ... } The pal parameter can optionally be used to return a palette for the FONT. The parameter param can be anything you like: you can use this to pass information to your loading routine, such as for instance the font height, the character range to load or the index number of a font in a datafile. If you choose to write your own font loading code, your function should be prepared to deal with a value of NULL for either of these parameters. SEE ALSO

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 struc- tures (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(myfont); 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. SEE ALSO
