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

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.

width
- the width to which to set the width of this BufferedImageFilter

method of the ImageConsumer
interface. If model
is null
, this method clears the current ColorModel
of this BufferedImageFilter
.
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.
