A circle of radius 23 drawn by the Bresenham algorithm. In computer graphics, the midpoint circle algorithm is an algorithm used to determine the points needed for rasterizing a circle. It is a generalization of Bresenham's line algorithm. The algorithm can be further generalized to conic sections. [1] [2] [3]
A counter is initialized to count the number of objects. A row-major scan is started for the entire image. If an object pixel is detected, then following steps are repeated while (Index !=0) Set the corresponding pixel to 0 in Image. A vector (Index) is updated with all the neighboring pixels of the currently set pixels.

Font rasterization is the process of converting text from a vector description (as found in scalable fonts such as TrueType fonts) to a raster or bitmap description. This often involves some anti-aliasing on screen text to make it smoother and easier to read.
In typography, a bullet or bullet point, •, is a typographical symbol or glyph used to introduce items in a list.For example: Red; Green; Blue; The bullet symbol may take any of a variety of shapes, such as circular, square, diamond or arrow.
