Constructor Detail

• BufferedImageFilter

  public BufferedImageFilter(BufferedImageOp op)

  Constructs a BufferedImageFilter with the specified single-source/single-destination operator.

  Parameters:

  op - the specified BufferedImageOp to use to filter a BufferedImage

  Throws:

  NullPointerException - if op is null

Method Detail

• getBufferedImageOp

  public BufferedImageOp getBufferedImageOp()

  Returns the BufferedImageOp.

  Returns:

  the operator of this BufferedImageFilter.

• 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.

  Specified by:

  setDimensions in interface  ImageConsumer

  Overrides:

  setDimensions in class  ImageFilter

  Parameters:

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

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

  See Also:

  ImageConsumer.setDimensions(int, int)

• setColorModel

  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.

  Specified by:

  setColorModel in interface  ImageConsumer

  Overrides:

  setColorModel in class  ImageFilter

  Parameters:

  model - the ColorModel to which to set the ColorModel of this BufferedImageFilter

  ImageConsumer.setColorModel(java.awt.image.ColorModel)

• 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.

  Specified by:

  setPixels in interface  ImageConsumer

  Overrides:

  setPixels in class  ImageFilter

  Parameters:

  x - the X coordinate of the upper-left corner of the area of pixels to be set

  y - the Y coordinate of the upper-left corner of the area of pixels to be set

  w - the width of the area of pixels

  h - the height of the area of pixels

  model - the specified ColorModel

  pixels - the array of pixels

  off - the offset into the pixels array

  scansize - the distance from one row of pixels to the next in the pixels array

  Throws:

  IllegalArgumentException - if width or height are less than zero.

  ImageConsumer.setPixels(int, int, int, int, ColorModel, byte[], int, int)

• 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.

  Specified by:

  setPixels in interface  ImageConsumer

  Overrides:

  setPixels in class  ImageFilter

  Parameters:

  x - the X coordinate of the upper-left corner of the area of pixels to be set

  y - the Y coordinate of the upper-left corner of the area of pixels to be set

  w - the width of the area of pixels

  h - the height of the area of pixels

  model - the specified ColorModel

  pixels - the array of pixels

  off - the offset into the pixels array

  scansize - the distance from one row of pixels to the next in the pixels array

  Throws:

  IllegalArgumentException - if width or height are less than zero.

  ImageConsumer.setPixels(int, int, int, int, ColorModel, int[], int, int)

• 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.

  Specified by:

  imageComplete in interface  ImageConsumer

  Overrides:

  imageComplete in class  ImageFilter

  Parameters:

  status - the status of image loading

  Throws:

  ImagingOpException - if there was a problem calling the filter method of the BufferedImageOp associated with this instance.
