public class BufferedImageFilter extends ImageFilter implements Cloneable
The 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.

consumer COMPLETESCANLINES, IMAGEABORTED, IMAGEERROR, RANDOMPIXELORDER, SINGLEFRAME, SINGLEFRAMEDONE, SINGLEPASS, STATICIMAGEDONE, TOPDOWNLEFTRIGHT public BufferedImageFilter(BufferedImageOp op)
Constructs a BufferedImageFilter with the specified single-source/single-destination operator.
op - the specified BufferedImageOp to use to filter a BufferedImage
NullPointerException - if op is nullpublic BufferedImageOp getBufferedImageOp()
Returns the BufferedImageOp.
BufferedImageFilter.public void setDimensions(int width,
int height) Filters the information provided in the 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.

width - the width to which to set the width of this BufferedImageFilter
height - the height to which to set the height of this BufferedImageFilter
ImageConsumer.setDimensions(int, int)public void setColorModel(ColorModel model)
Filters the information provided in the setColorModel 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.
