Package com.kheops.util.encoders

Class ImageEncoder

java.lang.Object

com.kheops.util.encoders.ImageEncoder

All Implemented Interfaces:

ImageConsumer

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.
