Embedding Fonts for Anti Aliasing in Flash AS3

// To use this method you must embed and "Export for AS" the font in the Flash IDE (eg. Flash CS3, Flash CS4).
// You Can do this by clicking the menu on the library panel, then go "New Font"
// Then select "Export for Actionscript, and give your font class name.
// The class name is the name that you will reference on the line directly below this.

var myFont = new MyFontClassName();

var myFormat:TextFormat = new TextFormat();
myFormat.size = 40;
myFormat.font = myFont.fontName;

var myText:TextField = new TextField();
myText.defaultTextFormat = myFormat;
myText.embedFonts = true;
myText.antiAliasType = AntiAliasType.ADVANCED;
myText.autoSize = "left";
myText.text = "Here is some pretty that is anti-aliased!";

Create a fading circular mask

Steve Ottenad - Nov 20, 2009 - AS3 Circle Drawing/ Clock Wipe Snippet

This Snippet works by drawing and then fading a succession of small triangles to make a circle/polygon.
It relies on TweenMax, a free tweening engine found at <a href="http://blog.greensock.com/tweenmax/." >http://blog.greensock.com/tweenmax/.</a>

centerX        (Number) - The X coordinate of the center of the circle to be drawn.
centerY        (Number) - The Y coordinate of the center of the circle to be drawn.
radius         (Number) - The desired radius of the circle.
increment      (Number) - The amount of degrees you want to add each time a wedge is drawn. If increment = 2, then 180 wedges will be drawn (360/2). If increment = 36, then 10 wedges will be drawn (360/10).
timeIncrement  (Number) - The amount of milliseconds between each wedge being drawn.
Container   (MovieClip) - The containing element.

Sample Usage: drawCircle(centerX, centerY , radius, increment , timeIncrement, container);

function drawCircle(centerX:Number, centerY:Number, radius:Number, increment:Number, timeIncrement:Number, container:MovieClip){

//Define Variables
var radius:Number = radius;
var iniX:Number = centerX;
var iniY:Number = centerY;
var increment:Number = increment;
var totalDegrees:Number = 0;
var degInRad:Number;
var degInRad1:Number;
outline.visible = true;

//Create Timer
var maskTimer:Timer = new Timer(timeIncrement);
maskTimer.addEventListener(TimerEvent.TIMER, drawSegment);

//Start Drawing
container.graphics.moveTo(iniX, iniY);
	function drawSegment(e:TimerEvent){
		if(totalDegrees < 362 && keepLoading){
			//Convert to Radians
			degInRad = totalDegrees * (Math.PI / 180);
			degInRad1 = Number(totalDegrees+increment) * (Math.PI / 180);
			//Find X,Y
			var x1:Number = radius * Math.cos( degInRad ) + iniX;
			var y1:Number = radius * Math.sin( degInRad ) + iniY;
			var x2:Number = radius * Math.cos( degInRad1 ) + iniX;
			var y2:Number = radius * Math.sin( degInRad1 ) + iniY;
			var wedge:Sprite = new Sprite();
			wedge.alpha = 0;
			//Define Color
			wedge.graphics.moveTo(iniX, iniY);
			wedge.graphics.lineTo(x1, y1);
			wedge.graphics.lineTo(x2, y2);
			wedge.graphics.lineTo(iniX, iniY);
			//Fade In (Time == 1 in this example
			TweenMax.to (wedge, 1, {alpha:1});
			totalDegrees+= increment
