Examples of java.awt.image.ImageConsumer

java.awt.image.ImageConsumer
The interface for objects expressing interest in image data through the ImageProducer interfaces. When a consumer is added to an image producer, the producer delivers all of the data about the image using the method calls defined in this interface. @see ImageProducer @version 1.25 02/14/06 @author Jim Graham
