The API uses the term "graphics context" for the parameter g, a reference to an object having methods that can modify the pixels of an output device or memory region. I would hesitate to say that it "points to" an area of RAM. Rather, it offers a pixel-oriented abstraction of the various ColorModel and SampleModel types encountered on disparate implementations. <http://download.oracle.com/javase/7/docs/api/java/awt/Graphics.html> <http://en.wikipedia.org/wiki/Pixel> -- John B.
