        Constructs a BufferedImageFilter with the specified single-source/single-destination operator.

    • Method Detail

      • getBufferedImageOp

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

        ImageConsumer.setColorModel(java.awt.image.ColorModel)
      • setPixels

        public void setPixels​(int x,

                              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.

                              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.
