How do I generate a list of lines to draw if I have pixel data for an image, so I don't have to draw every pixel? Any language will do, although I listed what I have a working knowledge for. C is ok as well. There was a limit to how many tags I could choose. Also, you can just point me toward an algorithm.
How can you achieve with lines what you have to do with pixels? You need to draw each pixel individually I'd say.
transforming an image into an array of lines to draw
