I'm not sure exactly what you mean by "un-continous," but assuming you mean rasterized graphics, there is far too much information to explain in an email-message. "Computer Graphics: Principles and Practice" by Foley and van Dam is the typically suggested book for learning computer graphics. In particular, you probably will be interested in Bresenham lines and circles, which are discussed practically anywhere graphics are taught. They are two simple and clever algorithms, and I'm sure you can find source code for them on the web. Note that they are not anti-aliased; they will not look as good as anti-aliased methods. Two GIMP-related libraries that implement this kind of thing are libart and cairo. You can find information on how to get them on the web.
