NAME

       create_bitmap_ex - Creates a memory bitmap specifying color depth. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       BITMAP *create_bitmap_ex(int color_depth, int width, int height);

DESCRIPTION

       Creates a bitmap in a specific color depth (8, 15, 16, 24 or 32 bits per pixel). Example:

	  /* Create screen sized bitmap in 32 bits per pixel. */
	  BITMAP *bmp = create_bitmap_ex(32, SCREEN_W, SCREEN_H);
	  if (!bmp)
	     abort_on_error("Couldn't create bitmap!");
	  /* Use the bitmap. */
	  ...
	  /* Destroy it when we don't need it any more. */
	  destroy_bitmap(bmp);

RETURN VALUE

       Returns	a  pointer  to	the created bitmap, or NULL if the bitmap could not be created. Remember to free this bitmap later to avoid memory
       leaks.
