All Implemented Interfaces:

ImageConsumer

Direct Known Subclasses:

GifEncoder

public abstract class ImageEncoder

extends Object

implements 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.
