ABSTRACT: Anti-aliasing is important for graphics and circle is no exception. Circle anti-aliasing algorithms
in existence are complex and their effect does not satisfy. A recursive algorithm was explored for circle anti-
aliasing. The recursive algorithm chooses two pixels closest to the ideal circle in each column and the grayscale
is calculated according to the distance between the center of a pixel and the circle. The ...
