锯齿线
jaggies/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.
