In this article, I want to explain and deduce the line drawing algorithm by Bresenham. Afterwards, I will show an optimized version which can be used to draw lines in Gecko based browsers like Mozilla or Firefox and Microsoft s Internet Explorer. As you know, HTML itself is not able to describe lines. Therefore, there is no built-in features in the above-mentioned browsers for drawing lines. By implementing the Bresenham algorithm with JavaScript while applying some tricks, we will be able to draw lines in a good manner in respect to the browser s runtime and memory footprints. -In this article, I want to explain and deduce the line drawing algorithm by Bresenham.
