  public java.awt.image.BufferedImage createCompatibleDestImage​(java.awt.image.BufferedImage src,
                                                                java.awt.image.ColorModel destCM)

  Specified by:

  createCompatibleDestImage in interface java.awt.image.BufferedImageOp

• getPoint2D

  public java.awt.geom.Point2D getPoint2D​(java.awt.geom.Point2D srcPt,
                                          java.awt.geom.Point2D dstPt)

  Specified by:

• getRenderingHints

  public java.awt.RenderingHints getRenderingHints​()

  Specified by:

• getPixels

  protected int[] getPixels​(java.awt.image.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​(java.awt.image.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:

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