The code also works with flash cs3

import fl.controls.TextInput;
import fl.controls.Label;

var myLabel:Label = new Label();
myLabel.text = "Caret Index Word";
myLabel.x = 5;
myLabel.y = 0;
addChild(myLabel);

var textInput:TextInput = new TextInput();
textInput.x = 100;
textInput.y = 10;
addChild(textInput);

var t:Timer = new Timer(100);
t.addEventListener(TimerEvent.TIMER, caretindex);

function caretindex(e:TimerEvent):void {
	var caretIndex:Number = textfield.getCharIndexAtPoint(textfield.mouseX, textfield.mouseY)
	if(caretIndex == -1) {
		return;
	}
	var str:String = textfield.text;
	var words:Array = str.split(' ');
	var n:Number = 0;
	while(n<=words.length){
		var subset:Array = words.slice(0, n);
		var sliceString:String = subset.join(' ');
		if(sliceString.length>caretIndex) {
			textInput.text = String(subset[n-1]);
			break
		}
		n++;
	}
}
t.start();

This code show how to use TextElement, TextBlock, FontDescription, TextBlock, TextLine

package druva{
import flash.display.Sprite;
import flash.text.engine.*;

public class TextTest extends Sprite {

public function TextTest() {

for (var j:int=0; j<=10; j++) {
var myString:String="Druva";
var myFormat:ElementFormat = new ElementFormat();

var myFontDesc:FontDescription=new FontDescription('Georgia','normal','italic','device');
myFormat.fontSize=2+2*j;
myFormat.fontDescription=myFontDesc;
myFormat.color = Math.random() * 0xFFFFEE;

var textElement:TextElement=new TextElement(myString, myFormat);
var textBlock:TextBlock = new TextBlock();
textBlock.content=textElement;

var myTextLine:TextLine=textBlock.createTextLine(null,300);

myTextLine.x = 30+(3*(j*(j+1)/2));
myTextLine.y = 150;

addChild(myTextLine);
myTextLine.addEventListener(Event.ENTER_FRAME, onLoop);
}

}
import flash.events.*;
private function onLoop(e:Event) {
e.currentTarget.rotationY += 3;
e.currentTarget.rotation = mouseX;
}
}
}

Flash is great!!

The below code shows how to use the class

import druva.NumberUtil;

trace('500', NumberUtil.getParity(500));
// true
trace('489', NumberUtil.getParity(489));
// false
trace('5', NumberUtil.getParity(5));
//false
trace('1', NumberUtil.getParity(1));
//true
trace('400', NumberUtil.getParity(400));
//false

This is the actual class

package druva {
  import flash.display.Sprite;

  public class NumberUtil extends Sprite{
    public function NumberUtil(){
    }

    public static function getParity(num:Number):String {
		return (num % 2) ? 'odd' : 'even';
	}

  }
}

Convert TextField to Bitmap

package {
	import flash.display.*;
	import flash.display.BitmapData;
	import flash.display.Sprite;
	import flash.text.TextField;
	import flash.text.TextFormat;
	import flash.text.TextFieldAutoSize;

	public class BitmapUtils extends Sprite {
		public function BitmapUtils() {
			addChild(tf2bm('Druva'));
		}
		public function tf2bm(str:String) {
			var fmt:TextFormat;
			var bmd:BitmapData;
			var bm:Bitmap;
			var tf:TextField;

			fmt = new TextFormat();
			fmt.font='Verdana';
			fmt.size=30;

			tf = new TextField();
			tf.text=str;
			tf.setTextFormat(fmt);
			tf.autoSize=TextFieldAutoSize.LEFT;
			bmd=new BitmapData(tf.width,tf.height,true,0);
			bmd.draw(tf);
			bm=new Bitmap(bmd);
			bm.smoothing=true;
			return bm
		}
	}

Simple Example to show how to use perlinNoise in Flash ActionScript

In the below example the stage is divided into two parts with two different effects

example

import flash.display.*;
import flash.events.Event;
import flash.geom.Point;

var _bitmap1:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight/2, true, 0xCCCCCC);
var _bitmap2:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight/2, true, 0xCCCCCC);

function perlinNoise() {
addChild(new Bitmap(_bitmap1));
_bitmap1.perlinNoise(10, 10, 2, 50, false, true,1, true);

var b:Bitmap = new Bitmap(_bitmap2);
b.y = stage.stageHeight/2;
addChild(b)
}

perlinNoise();

var t:Timer = new Timer(50)
t.addEventListener(TimerEvent.TIMER , onTimer);
var Size = 0;
var xPos = 0;
var yPos = 0;
function onTimer (e:TimerEvent) {
var point:Point=new Point(++xPos,++yPos);
_bitmap1.perlinNoise(10, 10, 2, 50, false, true,1, true, [point, point]);
++Size;
_bitmap2.perlinNoise(Size,Size, 2, 50, false, true,1, true, [point, point]);
if(Size > 50){
Size = 0;
}
}

t.start();
