man set_clip_state () - Turns on or off the clipping of a bitmap. Allegro game programming library.
NAME
set_clip_state - Turns on or off the clipping of a bitmap. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void set_clip_state(BITMAP *bitmap, int state)
DESCRIPTION
Turns on (if state is non-zero) or off (if state is zero) clipping for the specified bitmap. Turning clipping off may slightly speed up some drawing operations (usually a negligible difference, although every little helps) but will result in your program dying a horrible death if you try to draw beyond the edges of the bitmap.
