Class DupableImage

java.lang.Object
  java.awt.Image
      com.davisor.graphics.DupableImage

All Implemented Interfaces:

com.davisor.core.Dupable, java.awt.image.ImageConsumer, java.awt.image.ImageProducer, java.awt.image.RenderedImage, java.awt.image.WritableRenderedImage

public class DupableImage

extends java.awt.Image

implements com.davisor.core.Dupable, java.awt.image.ImageConsumer, java.awt.image.ImageProducer, java.awt.image.WritableRenderedImage

DupableImage implements an enhaced replacement to standard Java BufferedImage class. In particular, Dupable images are mutable, and support deep copy operation and the ImageConsumer and ImageProducer interfaces.
