register_bitmap_file_type(3)    Allegro manual    register_bitmap_file_type(3)

NAME
       register_bitmap_file_type - Registers custom bitmap loading/saving
       functions. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void register_bitmap_file_type(const char *ext, BITMAP *(*load)(const
       char *filename, RGB *pal), int (*save)(const char *filename, BITMAP
       *bmp, const RGB *pal));

DESCRIPTION
       Informs the load_bitmap() and save_bitmap() functions of a new file
       type, providing routines to read and write images in this format
       (either function may be NULL). The functions you supply must follow the
       same prototype as load_bitmap() and save_bitmap(). Example:

          BITMAP *load_dump(const char *filename, RGB *pal)
          {
             ...
          }

          int save_dump(const char *filename, BITMAP *bmp, const RGB *pal)
          {
             ...
          }

             register_bitmap_file_type("dump", load_dump, save_dump);
