jaggies
(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.
