/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.

(2) In computer graphics, aliasing is the stair-stepped appearance of diagonal lines when there are not enough pixels in the image or on screen to represent them realistically. Also called "stair-stepping" and "jaggies." See anti-aliasing.
