Color Wheel Code Sample

The community of this developer forum has been among one of the best i've ever been apart of.  Kudos to you all who have been instrumental in its upbringing.


As a token of my appreciation, i'd like to offer some code from my own library, which hopefully some will find useful.


Attached is my ColorWheel class that creates a vector graphic of the color spectrum, with or without gradating lightness.  i plan on publishing it as recipe on the Adobe® Developer CookBooks site in the coming weeks with a detailed explanation, but since i haven't written that yet i'll simply post the code here and offer answers to any questions.




Here is an example on the use of these classes, which are available for download below.

import com.mattie.utils.colorUtils.ColorWheel;
import com.mattie.utils.colorUtils.ColorWheelQuality;
import flash.display.Sprite;

//SWF Metadata Tag
[SWF(width="1024", height="600", frameRate="30", backgroundColor="#FFFFFF")]

public class Main extends Sprite
private var rad:uint = stage.stageWidth / 6;

public function Main()

private function init():void
var colorWheel:ColorWheel = new ColorWheel(rad, ColorWheelQuality.LOW, NaN);
colorWheel.x = rad;

var whiteWheel:ColorWheel = new ColorWheel(rad, ColorWheelQuality.LOW);
whiteWheel.x = rad * 3;

var blackWheel:ColorWheel = new ColorWheel(rad, ColorWheelQuality.LOW, 0);
blackWheel.x = rad * 5

colorWheel.y = whiteWheel.y = blackWheel.y = stage.stageHeight / 2;
