al_lock_bitmap_blocked(3)   Library Functions Manual   al_lock_bitmap_blocked(3)

NAME
     al_lock_bitmap_blocked - Allegro 5 API

SYNOPSIS
	    #include <allegro5/allegro.h>

	    ALLEGRO_LOCKED_REGION *al_lock_bitmap_blocked(ALLEGRO_BITMAP *bitmap,
	       int flags)

DESCRIPTION
     Like  al_lock_bitmap(3),  but  allows  locking bitmaps with a blocked pixel
     format   (i.e. a	format	 for   which   al_get_pixel_block_width(3)    or
     al_get_pixel_block_height(3) do not return 1) in that format.  To that end,
     this  function  also  does not allow format conversion.  For bitmap formats
     with  a  block  size  of  1,  this  function  is	identical   to	 calling
     al_lock_bitmap(bmp, al_get_bitmap_format(bmp), flags).

	    Note:  Currently  there  are no drawing functions that work when the
	    bitmap is locked with a  compressed  format.   al_get_pixel(3)  will
	    also not work.

SINCE
     5.1.9
