This supplement to Chapter 11 has two main parts. The first part
examines image handling and processing with the Java 2D API. We
previously discussed Java 2D graphics drawing techniques in the
Chapter 6: Supplements section.
Java 2D also includes extensive imaging tools.
The second part looks at the problem of flicker
in animations on AWT components. Three techniques are discussed
that reduce the flickering. (The most effective technque - double
buffering - is used by default when drawing on Swing components
so flicker is not such a problem with Swing animations.)

Images - create instances of BufferedImage,
then use ImageIO
class methods to save and read files in standard image formats.

modifying them and creating new images and animations from
