Generating High-Resolution graphics can be done according to three methods

Interact with a RAM space, then save the result in a file: that's what you do when you use a classical draw program.
Calculate the pixels via an algorithm, display them on the screen, then save the result in a file.
Calculate the pixels via an algorithm, and save them directly in a file.

The tutorials presented here describe the basic techniques used for the three methods. These techniques can be applied to raytracing and fractals rendering, as developed in the other sections of the Mandelbrot Dazibao.
