- The blurring of the jagged "stair-step" appearance in graphical elements
such as lines, curves, circles, and particularly in fonts. Jagged edges occur
when the resolution of an image is too coarse to achieve the appearance of smoothness.
Thus, smoothing can blur the roughness of a jagged line by shading or colouring
neighbouring pixels. This technique makes the transition between light and dark
(or between two colours) less distinct and therefore less visible, at the cost
of making it look more blurry.
Also known as smoothing, and sometimes abbreviated to simply AA.
