Class BufferedImageFilter
java.lang.Object | +--java.awt.image.ImageFilter | +--java.awt.image.BufferedImageFilter
- public class BufferedImageFilter
- extends ImageFilter
- implements Cloneable
- extends ImageFilter
This 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.

BufferedImageFilter
public BufferedImageFilter(BufferedImageOp op)
- Constructs a BufferedImageFilter with the specified single-source/single-destination operator.
| Method Detail |
getBufferedImageOp
public BufferedImageOp getBufferedImageOp()
- Returns the BufferedImageOp.
setDimensions
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.
- Overrides:
- setDimensions in class ImageFilter
- See Also:
ImageConsumer.setDimensions(int, int)
setColorModel
public void setColorModel(ColorModel model)
- Filters the information provided in the setColorModel 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.
- Overrides:
- setColorModel in class ImageFilter
setPixels
public void setPixels(int x,
int y,
int w,
int h,
ColorModel model,
byte[] pixels,
int off,
int scansize)
- Filters the information provided in the setPixels method of the
ImageConsumer interface which takes an array of bytes.
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.
- Overrides:
- setPixels in class ImageFilter
setPixels
public void setPixels(int x,
int y,
int w,
int h,
ColorModel model,
int[] pixels,
int off,
int scansize)
- Filters the information provided in the setPixels method of the
ImageConsumer interface which takes an array of integers.
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.
- Overrides:
- setPixels in class ImageFilter
imageComplete
public void imageComplete(int status)
- Filters the information provided in the imageComplete 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.
- Overrides:
- imageComplete in class ImageFilter
- Throws:
- ImagingOpException - if there was a problem calling the filter method of the BufferedImageOp associated with this instance.

ImageConsumer.imageComplete(int)
