register_bitmap_file_type3alleg4

Usage

Overview

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);
