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:

Constructor Details- 
BufferedImageFilterConstructs aBufferedImageFilterwith the specified single-source/single-destination operator.- Parameters:
- op- the specified- BufferedImageOpto use to filter a- BufferedImage
- Throws:
- NullPointerException- if op is null

- 
Method Details- 
getBufferedImageOpReturns theBufferedImageOp.- Returns:
- the operator of this BufferedImageFilter.
 
- 
setDimensionspublic 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 interface- ImageConsumer
- Overrides:
- setDimensionsin 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:
 
- 
setColorModelFilters 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 interface- ImageConsumer
- Overrides:
- setColorModelin class- ImageFilter
- Parameters:
- model- the- ColorModelto which to set the- ColorModelof this- BufferedImageFilter
- See Also:
 
- 
setPixelspublic 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 interface- ImageConsumer
- Overrides:
- setPixelsin 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- pixelsarray
- scansize- the distance from one row of pixels to the next in the- pixelsarray
- Throws:
- IllegalArgumentException- if width or height are less than zero.
- See Also:
 
- 
setPixelspublic 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 interface- ImageConsumer
- Overrides:
- setPixelsin 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- pixelsarray
- scansize- the distance from one row of pixels to the next in the- pixelsarray
- Throws:
- IllegalArgumentException- if width or height are less than zero.

imageCompletepublic 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 interface- ImageConsumer
- Overrides:
- imageCompletein class- ImageFilter
- Parameters:
- status- the status of image loading
- Throws:
- ImagingOpException- if there was a problem calling the filter method of the- BufferedImageOpassociated with this instance.
