Acme.JPM.Encoders
Class ImageEncoder

java.lang.Object
  Acme.JPM.Encoders.ImageEncoder

All Implemented Interfaces:

java.awt.image.ImageConsumer

Direct Known Subclasses:

GifEncoder, PpmEncoder

public abstract class ImageEncoder
extends java.lang.Object
implements java.awt.image.ImageConsumer

Abstract class for writing out an image.

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.
