public abstract class ImageEncoder
extends java.lang.Object
implements java.awt.image.ImageConsumer
A framework for classes that encode and write out an image in a particular file format.
This provides a simplified rendition of the ImageConsumer interface. It always delivers the pixels as ints in the RGBdefault color model. It always provides them in top-down left-right order. If you want more flexibility you can always implement ImageConsumer directly.
