public class BufferedImageFilter extends ImageFilter implements Cloneable
BufferedImageFilter class subclasses an
ImageFilter to provide a simple means of
using a single-source/single-destination image operator
(BufferedImageOp) to filter a BufferedImage
in the Image Producer/Consumer/Observer
paradigm. Examples of these image operators are: ConvolveOp,
AffineTransformOp and LookupOp.ImageFilter,
BufferedImage,
BufferedImageOpconsumerCOMPLETESCANLINES, IMAGEABORTED, IMAGEERROR, RANDOMPIXELORDER, SINGLEFRAME, SINGLEFRAMEDONE, SINGLEPASS, STATICIMAGEDONE, TOPDOWNLEFTRIGHT| Constructor and Description |

setDimensions method
of the ImageConsumer interface.
Note: This method is intended to be called by the
ImageProducer of the Image whose pixels are
being filtered. Developers using this class to retrieve pixels from
an image should avoid calling this method directly since that
operation could result in problems with retrieving the requested
pixels.

If model is null, this
method clears the current ColorModel of this

whose pixels are being filtered. Developers using this
class to retrieve pixels from an image
should avoid calling this method directly since that
operation could result in problems with retrieving the
