class BufferedImageFilter

java.lang.Object java.awt.image.ImageFilter java.awt.image.BufferedImageFilter

All Implemented Interfaces:

ImageConsumer, Cloneable

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 ({@link BufferedImageOp}) to filter a BufferedImage in the Image Producer/Consumer/Observer paradigm. Examples of these image operators are: {@link ConvolveOp}, {@link AffineTransformOp} and {@link LookupOp}.

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

getBufferedImageOp

public BufferedImageOp getBufferedImageOp()

Returns the BufferedImageOp.

Returns:

the operator of this BufferedImageFilter.

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

Parameters:

status - the status of image loading

setColorModel

public void setColorModel(ColorModel model)

Filters the information provided in the {@link ImageConsumer#setColorModel(ColorModel) 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.

Overrides:

setColorModel in class ImageFilter

Parameters:

model - the {@link ColorModel} to which to set the ColorModel of this BufferedImageFilter

setDimensions

public void setDimensions(int width,
                          int height)

Filters the information provided in the {@link ImageConsumer#setDimensions(int, int) setDimensions } method of the {@link ImageConsumer} interface.

Note: This method is intended to be called by the {@link 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

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

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

Parameters:

x

y

w

h

model

pixels

off

scansize

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

Parameters:

x

y

w

h

model

pixels

off

scansize
