## 21.9 java.awt.image.ImageProducer (JDK 1.0)

###

This interface defines the methods that any class that produces image data must define to enable communication with `ImageConsumer` classes. An `ImageConsumer` registers itself as interested in a producer's image by calling the `addConsumer()` method.

Most applications never need to use or implement this interface.

    public abstract interface ImageProducer {
        // Public Instance Methods
                public abstract void addConsumer(ImageConsumer ic);
                public abstract boolean isConsumer(ImageConsumer ic);
                public abstract void removeConsumer(ImageConsumer ic);
                public abstract void requestTopDownLeftRightResend(ImageConsumer ic);
                public abstract void startProduction(ImageConsumer ic);
    }

### Implemented By:

`FilteredImageSource, MemoryImageSource`

### Passed To:

`Component.createImage(), ComponentPeer.createImage(), FilteredImageSource(), ImageFilter.resendTopDownLeftRight(), PixelGrabber(), Toolkit.createImage()`

### Returned By:

`Image.getSource()`
