Examples of java.awt.image.ImageProducer

java.awt.image.ImageProducer
The interface for objects which can produce the image data for Images. Each image contains an ImageProducer which is used to reconstruct the image whenever it is needed, for example, when a new size of the Image is scaled, or when the width or height of the Image is being requested. @see ImageConsumer @version 1.21 11/17/05 @author Jim Graham
