Class AbstractFilter

Method Details

• filter

  public abstract BufferedImage filter(BufferedImage src, BufferedImage dest)

  Specified by:

  filter in interface BufferedImageOp

• getBounds2D

  public Rectangle2D getBounds2D(BufferedImage src)

  Specified by:

  getBounds2D in interface BufferedImageOp

• createCompatibleDestImage

  public BufferedImage createCompatibleDestImage(BufferedImage src, ColorModel destCM)

  Specified by:

  createCompatibleDestImage in interface BufferedImageOp

• getPoint2D

  public Point2D getPoint2D(Point2D srcPt, Point2D dstPt)

  Specified by:

  getPoint2D in interface BufferedImageOp

• getRenderingHints

  public RenderingHints getRenderingHints()

  Specified by:

  getRenderingHints in interface BufferedImageOp

• getPixels

  protected int[] getPixels(BufferedImage img, int x, int y, int w, int h, int[] pixels)

• setPixels

  protected void setPixels(BufferedImage img, int x, int y, int w, int h, int[] pixels)

  Writes a rectangular area of pixels in the destination BufferedImage. Calling this method on an image of type different from BufferedImage.TYPE_INT_ARGB and BufferedImage.TYPE_INT_RGB will unmanage the image.

  Parameters:

  img - the destination image

  x - the x location at which to start storing pixels

  y - the y location at which to start storing pixels

  w - the width of the rectangle of pixels to store

  h - the height of the rectangle of pixels to store

  pixels - an array of pixels, stored as integers

  Throws:

  IllegalArgumentException - is pixels is non-null and of length < w*h
