register_bitmap_file_type(3alleg4)				  Allegro manual				register_bitmap_file_type(3alleg4)

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);

NAME

       save_bitmap - Saves a bitmap into any supported file format. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int save_bitmap(const char *filename, BITMAP *bmp, const RGB *pal);

DESCRIPTION

       Writes  a  bitmap into a file, using the specified palette, which should be an array of 256 RGB structures. The output format is determined
       from the filename extension: at present this function supports BMP, PCX and TGA formats.

       Two things to watch out for: on some video cards it may be faster to copy the screen to a memory bitmap and save the latter, and if you use
       this to dump the screen into a file you may end up with an image much larger than you were expecting, because Allegro often creates virtual
       screens larger than the visible screen. You can get around this by using a sub-bitmap to specify which part of the screen to save, eg:

	  BITMAP *bmp;
	  PALETTE pal;
	  ...
	  get_palette(pal);
	  bmp = create_sub_bitmap(screen, 0, 0, SCREEN_W, SCREEN_H);
	  save_bitmap("dump.pcx", bmp, pal);
	  destroy_bitmap(bmp);

RETURN VALUE

       Returns non-zero on error.
