public class BufferedImageFilter

extends ImageFilter

implements Cloneable

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.

Constructor Summary

BufferedImageFilter(BufferedImageOp op)
Constructs a BufferedImageFilter with the specified single-source/single-destination operator.

Method Summary

BufferedImageOp	getBufferedImageOp() Returns the BufferedImageOp.
void	imageComplete(int status) Filters the information provided in the imageComplete method of the ImageConsumer interface.
void	setColorModel(ColorModel model) Filters the information provided in the setColorModel method of the ImageConsumer interface.
void	setDimensions(int width, int height) Filters the information provided in the setDimensions method of the ImageConsumer interface.
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.
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.

Constructor Detail

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

See Also:

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.

Overrides:

setPixels in class ImageFilter

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.

Overrides:

setPixels in class ImageFilter

See Also:

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.

Overrides:

imageComplete in class ImageFilter

Throws:

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