Method

intdistanceToColor(final int distance)
distance To Color 
return new Color(INTENSITY_MAX - distance, INTENSITY_MAX - distance, INTENSITY_MAX - distance,
        INTENSITY_MAX).getRGB();
voiddrawArc(Point2D start, double distance, double startAngle, double arcAngle, boolean fill, Graphics2D g2, Color color)
draw Arc 
int r2 = (int) (distance * 2);
int x = (int) (start.getX() - distance);
int y = (int) (start.getY() - distance);
g2.setColor(color);
if (fill)
    g2.fillArc(x, y, r2, r2, (int) Math.toDegrees(startAngle), (int) Math.toDegrees(arcAngle));
else
    g2.drawArc(x, y, r2, r2, (int) Math.toDegrees(startAngle), (int) Math.toDegrees(arcAngle));

doublegetDistance(int c1, Color c2)
get Distance 
c1 = 0xff000000 | c1;
double rmean = ((c1 >> 16) + c2.getRed()) / 2.0;
double r = ((c1 >> 16) & 0xFF) - c2.getRed();
double g = ((c1 >> 8) & 0xFF) - c2.getGreen();
int b = ((c1 >> 0) & 0xFF) - c2.getBlue();
double weightR = 2 + rmean / 256.0;
double weightG = 4.0;
double weightB = 2 + (255 - rmean) / 256.0;
...
intgetMaxDistance(final Color first, final Color second)
Returns the largest absolute difference between the red, green and blue values of the two colors. 
int distance = Math.abs(first.getRed() - second.getRed());
if (Math.abs(first.getGreen() - second.getGreen()) > distance) {
    distance = Math.abs(first.getGreen() - second.getGreen());
if (Math.abs(first.getBlue() - second.getBlue()) > distance) {
    distance = Math.abs(first.getBlue() - second.getBlue());
return Math.abs(distance);
...
doublepixelDistance(final Color col1, final Color col2)
Calculates the distance between two colors. 
int r1 = col1.getRed();
int g1 = col1.getGreen();
int b1 = col1.getBlue();
int r2 = col2.getRed();
int g2 = col2.getGreen();
int b2 = col2.getBlue();
double pixelDistance = Math
        .sqrt(((r1 - r2) * (r1 - r2)) + ((g1 - g2) * (g1 - g2)) + ((b1 - b2) * (b1 - b2)));
