public abstract class AbstractFilter extends Object implements BufferedImageOp

Provides an abstract implementation of the BufferedImageOp interface. This class can be used to created new image filters based on 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)
      Returns an array of integer pixels in the default RGB color model (TYPE_INT_ARGB) and default sRGB color space, from a portion of the image data.
      Parameters:
      img - Image.
      x - The starting X coordinate
      y - The starting Y coordinate
      w - Width of region.
      h - Height of region.
      pixels - If not null, the pixels are written here.
      Returns:
      Array or RGB 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
