      Parameters:

      colorMap - Color[]

  • Method Details

    • getColor

      public Color getColor(int i)

    • getPalette

      public Color[] getPalette()

    • getPaletteSize

      public int getPaletteSize()
      Returns:
      the number of colors in the palette

    • createColorPalette

      protected Color[] createColorPalette(int suggestedNumberOfColors, Color[] colorMap)
      Allocates colors across a range.
      Parameters:
      suggestedNumberOfColors - palette resolution; if colorPalette.length does not evenly divide into this number, the actual number of colors in the palette will be rounded down.
      colorMap - the simplest color map is { minColor, maxColor }; you might, however, want to go through intermediate colors instead of following a straight-line route through the color space.
      Returns:
      Color[] the color palette

    • getStepSize

      protected int getStepSize(int minColor, int maxColor, int totalColors)
      Calculate how fast we have to change color components. Assume min and max colors are different!
      Parameters:
      minColor - red, green, or blue component of the RGB color
      maxColor - red, green, or blue component of the RGB color
      totalColors - int
      Returns:
      positive or negative step size
