In a graphics display with a Draw Thick Line Command, errors occur at the boundaries of a display area when only simple software clipping is used. Disclosed is an arrangement in which, firstly, an expanded window is clipped by software and, secondly, a smaller display area is defined by hardware scissoring to display thick lines correctly.
