java.lang.Object

   +----java.awt.image.FilteredImageSource

public class FilteredImageSource
extends Object
implements ImageProducer

This class is an implementation of the ImageProducer interface which takes an existing image and a filter object and uses them to produce image data for a new filtered version of the original image. Here is an example which filters an image by swapping the red and blue compents:

	Image src = getImage("doc:///demo/images/duke/T1.gif");
	ImageFilter colorfilter = new RedBlueSwapFilter();
	Image img = createImage(new FilteredImageSource(src.getSource(),
							colorfilter));

See Also:: ImageProducer

FilteredImageSource(ImageProducer, ImageFilter): Construct an ImageProducer object from an existing ImageProducer and a filter object.

addConsumer(ImageConsumer): Add an ImageConsumer to the list of consumers interested in data for this image.
isConsumer(ImageConsumer): Determine if an ImageConsumer is on the list of consumers currently interested in data for this image.
removeConsumer(ImageConsumer): Remove an ImageConsumer from the list of consumers interested in data for this image.
requestTopDownLeftRightResend(ImageConsumer): Request that a given ImageConsumer have the image data delivered one more time in top-down, left-right order.
startProduction(ImageConsumer): Add an ImageConsumer to the list of consumers interested in data for this image, and immediately start delivery of the image data through the ImageConsumer interface.

FilteredImageSource

  public FilteredImageSource(ImageProducer orig,
                             ImageFilter imgf)

Construct an ImageProducer object from an existing ImageProducer and a filter object.

addConsumer

  public synchronized void addConsumer(ImageConsumer ic)

Add an ImageConsumer to the list of consumers interested in data for this image.

See Also:: ImageConsumer

isConsumer

  public synchronized boolean isConsumer(ImageConsumer ic)

Determine if an ImageConsumer is on the list of consumers currently interested in data for this image.

Returns:: true if the ImageConsumer is on the list; false otherwise
See Also:: ImageConsumer

removeConsumer

  public synchronized void removeConsumer(ImageConsumer ic)

Remove an ImageConsumer from the list of consumers interested in data for this image.

See Also:: ImageConsumer

startProduction

  public void startProduction(ImageConsumer ic)

Add an ImageConsumer to the list of consumers interested in data for this image, and immediately start delivery of the image data through the ImageConsumer interface.

See Also:: ImageConsumer

requestTopDownLeftRightResend

  public void requestTopDownLeftRightResend(ImageConsumer ic)

Request that a given ImageConsumer have the image data delivered one more time in top-down, left-right order. The request is handed to the ImageFilter for further processing, since the ability to preserve the pixel ordering depends on the filter.
