Aliasing & Anti-aliasing
Aliasing is the visual stair-stepping of edges that occurs in an image when the resolution is too low. Anti-aliasing is the smoothing of jagged edges in digital images by averaging the colors of the pixels at a boundary.
The letter on the left is aliased. The letter on the right has had anti-aliasing applied to make the edges appear smoother.
