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));

See Also:: ImageProducer

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

    method FilteredImageSource(orig=ImageProducer, -
                               imgf=ImageFilter) public

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

See Also:: ImageFilter, createImage

addConsumer

    method addConsumer(ic=ImageConsumer)  public    protect

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

See Also:: ImageConsumer

isConsumer

    method isConsumer(ic=ImageConsumer) returns boolean public    protect

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
See Also:: ImageConsumer

removeConsumer

    method removeConsumer(ic=ImageConsumer)  public    protect

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

See Also:: ImageConsumer

startProduction

    method startProduction(ic=ImageConsumer)  public

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.

See Also:: ImageConsumer

requestTopDownLeftRightResend

    method requestTopDownLeftRightResend(ic=ImageConsumer)  public

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.
