Package Summary  Overview Summary

class:BufferedImageFilter [NONE]
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 (BufferedImageOp) to filter a BufferedImage in the Image Producer/Consumer/Observer paradigm. Examples of these image operators are: ConvolveOp, AffineTransformOp and LookupOp.
See Also:
ImageFilter, BufferedImage, BufferedImageOp

constructor:BufferedImageFilter(java.awt.image.BufferedImageOp) [NONE]

  • 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:getBufferedImageOp() [NONE]

  • getBufferedImageOp

    public BufferedImageOp getBufferedImageOp()
    Returns the BufferedImageOp.
    Returns:
    the operator of this BufferedImageFilter.

    • method:setDimensions(int,int) [NONE]

    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)

    method:setColorModel(java.awt.image.ColorModel) [NONE]

    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
    See Also:
    ImageConsumer.setColorModel(java.awt.image.ColorModel)

    method:setPixels(int,int,int,int,java.awt.image.ColorModel,byte[],int,int) [NONE]

    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.
    See Also:
    ImageConsumer.setPixels(int, int, int, int, ColorModel, byte[], int, int)

    method:setPixels(int,int,int,int,java.awt.image.ColorModel,int[],int,int) [NONE]

    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.
    See Also:
    ImageConsumer.setPixels(int, int, int, int, ColorModel, int[], int, int)

    method:imageComplete(int) [NONE]

    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.
