This algorithm lights five pixels in a loop between the coordinate information of line's start and end points. Therefore, the speedof generating of straight line can be accelerated. Compared with the four-step, it is the speed that increased by about 20% while the complexity is almost the same. Meanwhile the five-step still maintains the precise of the traditional line scan conversion algorithm.
