Class TranslateRed

java.lang.Object

org.apache.batik.ext.awt.image.rendered.AbstractRed

org.apache.batik.ext.awt.image.rendered.TranslateRed

All Implemented Interfaces:

RenderedImage, CachableRed

public class TranslateRed
extends AbstractRed

This is a special case of an Affine that only contains integer translations, this allows it to do it's work by simply changing the coordinate system of the tiles.
