    • drawColorBar

      public void drawColorBar(Graphics g, int x, int y, int width, int height)
      Draws a color bar with the LUT, with a black rectangle around. 'x' is the coordinate of the field for the lowest LUT color. Note that 'width' is the width of the area for the LUT colors; thus no colors will be omitted with a 256-entry LUT if width=256. The left line of the rectangle is at x, the right one at x+width+1.

      public void drawUnscaledColorBar(ImageProcessor ip, int x, int y, int width, int height)
