Summary

In this chapter we learned how to draw geometrical primitives using control points, perform transformations of the coordinate system, and work with colors. Also, we studied how to accumulate drawings in the offscreen buffer and considered the generative art example of using it. Finally, we learned how to save the current screen image to the file.

In the next chapter we will continue learning 2D graphics and will consider one powerful method of generating fascinating animations and drawings – particle systems.
