Aliasing (Aliasing)

Aliasing (Aliasing) refers to the image in a non-linear (slash) lines appear jagged, such as round the edges. Why appear jagged?, in fact, the reason is simple: because the composition of the image pixels are square.

Anti-aliasing (Anti-aliasing)

Aliasing edges by average pixel method so that the image's edge looks smoother.

In the example above, some blue pixel insert into yellow edge pixels, at the same time, some yellow pixel insert into blue edge pixels. This transfer allows image circle from yellow to blue background process is gradual and smooth lines and more. Most image editing software with "aliasing" option, this option can be used for the type of font, drawing lines, shapes, wide selection and so on. In addition, all digital cameras have built-in "aliasing" feature that enables the photos look smoother.
