Class BufferedImageFilter
- All Implemented Interfaces:
ImageConsumer,Cloneable
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.- See Also:

Method Details
-
getBufferedImageOp
Returns theBufferedImageOp.- Returns:
- the operator of this
BufferedImageFilter.
-
setDimensions
public void setDimensions(int width, int height) Filters the information provided in thesetDimensionsmethod of theImageConsumerinterface.Note: This method is intended to be called by the
ImageProducerof theImagewhose 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:
setDimensionsin interfaceImageConsumer- Overrides:
setDimensionsin classImageFilter- Parameters:
width- the width to which to set the width of thisBufferedImageFilterheight- the height to which to set the height of thisBufferedImageFilter- See Also:
-
setColorModel
Filters the information provided in thesetColorModelmethod of theImageConsumerinterface.If
modelisnull, this method clears the currentColorModelof thisBufferedImageFilter.Note: This method is intended to be called by the
ImageProducerof theImagewhose 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:
setColorModelin interfaceImageConsumer- Overrides:
setColorModelin classImageFilter- Parameters:
model- theColorModelto which to set theColorModelof thisBufferedImageFilter- See Also:
-
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 thesetPixelsmethod of theImageConsumerinterface which takes an array of bytes.Note: This method is intended to be called by the
ImageProducerof theImagewhose 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:
setPixelsin interfaceImageConsumer- Overrides:
setPixelsin classImageFilter- Parameters:
x- the X coordinate of the upper-left corner of the area of pixels to be sety- the Y coordinate of the upper-left corner of the area of pixels to be setw- the width of the area of pixelsh- the height of the area of pixelsmodel- the specifiedColorModelpixels- the array of pixelsoff- the offset into thepixelsarrayscansize- the distance from one row of pixels to the next in thepixelsarray- Throws:
IllegalArgumentException- if width or height are less than zero.- See Also:
-
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 thesetPixelsmethod of theImageConsumerinterface which takes an array of integers.Note: This method is intended to be called by the
ImageProducerof theImagewhose 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:
setPixelsin interfaceImageConsumer- Overrides:
setPixelsin classImageFilter- Parameters:
x- the X coordinate of the upper-left corner of the area of pixels to be sety- the Y coordinate of the upper-left corner of the area of pixels to be setw- the width of the area of pixelsh- the height of the area of pixelsmodel- the specifiedColorModelpixels- the array of pixelsoff- the offset into thepixelsarrayscansize- the distance from one row of pixels to the next in thepixelsarray- Throws:
IllegalArgumentException- if width or height are less than zero.- See Also:
-
imageComplete
public void imageComplete(int status) Filters the information provided in theimageCompletemethod of theImageConsumerinterface.Note: This method is intended to be called by the
ImageProducerof theImagewhose 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:
imageCompletein interfaceImageConsumer- Overrides:
imageCompletein classImageFilter- Parameters:
status- the status of image loading- Throws:
ImagingOpException- if there was a problem calling the filter method of theBufferedImageOpassociated with this instance.- See Also:
