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);
