# Class java.awt.image.FilteredImageSource

    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));

##

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

##

addConsumer(ImageConsumer)
  Adds an ImageConsumer to the list of consumers interested in data for this image.
isConsumer(ImageConsumer)
  Determines whether an ImageConsumer is on the list of consumers currently interested in data for this image.
removeConsumer(ImageConsumer)
  Removes an ImageConsumer from the list of consumers interested in data for this image.
requestTopDownLeftRightResend(ImageConsumer)
  Requests that a given ImageConsumer have the image data delivered one more time in top-down, left-right order.
startProduction(ImageConsumer)
  Adds an ImageConsumer to the list of consumers interested in data for this image, and immediately starts delivery of the image data through the ImageConsumer interface.

FilteredImageSource

     public FilteredImageSource(ImageProducer orig,
                                ImageFilter imgf)

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

    ImageFilter, createImage

##

addConsumer

     public synchronized void addConsumer(ImageConsumer ic)

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

    ImageConsumer

isConsumer

     public synchronized boolean isConsumer(ImageConsumer ic)

  Determines whether 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

removeConsumer

     public synchronized void removeConsumer(ImageConsumer ic)

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

  See Also:
    ImageConsumer

startProduction

     public void startProduction(ImageConsumer ic)

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

    ImageConsumer

requestTopDownLeftRightResend

     public void requestTopDownLeftRightResend(ImageConsumer ic)

  Requests 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.
