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);
