staircasing

   <graphics> /jag'eez/ (Or "staircase") The "staircase" effect
   observable when an edge (especially a linear edge of very
   shallow or steep slope) is rendered on a {bitmap display} (as
   opposed to a {vector display}).  The effect is even more
   pronounced when a bitmap image or text in a bitmap font is
   enlarged.  {Outline fonts} and {anti-aliasing} are two
   techniques used to solve this problem with text.
