This code show how to use PerspectiveProjection, projectionCenter tranform, point

var img:Bitmap=new Bitmap(new heart(158, 58));
img.x=-158/2;
img.y=-58/2;
var holder:Sprite=new Sprite();
addChild(holder);
holder.x=stage.stageWidth/2;
holder.y=stage.stageHeight/2;
holder.addChild(img);

var pp:PerspectiveProjection=new PerspectiveProjection();
pp.fieldOfView = 120
pp.projectionCenter=new Point(holder.x,holder.y);
holder.transform.perspectiveProjection=pp;

function swingImage(e:Event):void {
	holder.rotationY+=3;
}
this.addEventListener(Event.ENTER_FRAME, swingImage);

Import an image into the flash
convert to movieclip
give identifier as sample

and here is the code

var img:sample = new sample();
addChild(img);

img.x = stage.stageWidth/2;
img.y = stage.stageHeight/2;

img.filters = [new ColorMatrixFilter([0.3086, 0.6094, 0.0820, 0, 0, 0.3086, 0.6094, 0.0820, 0, 0, 0.3086, 0.6094, 0.0820, 0, 0, 0, 0, 0, 1, 0])];

Import an image into the flash

and here is the code

var img:sample = new sample();
addChild(img);

img.x = stage.stageWidth/2;
img.y = stage.stageHeight/2;

img.filters = [new ColorMatrixFilter([-1, 0, 0, 0, 255, 0, -1, 0, 0, 255, 0, 0, -1, 0, 255, 0, 0, 0, 1, 0])];

This logic also works for flex

package  {
     import flash.filters.ColorMatrixFilter;
     import flash.display.MovieClip;
     import flash.display.Loader;
	 import fl.controls.Slider;
     import flash.net.URLRequest;
     import fl.motion.*;
     import flash.events.Event;  

     public class AdjustColorExample extends MovieClip
     {
	 	 private var loader:Loader = new Loader();
		 private var Br_slider:Slider;
		 private var co_slider:Slider;
		 private var hu_slider:Slider;
		 private var sa_slider:Slider;
         public function AdjustColorExample() {
             var imgUrl:String = "http://www.helpexamples.com/flash/images/image1.jpg";
             loader.contentLoaderInfo.addEventListener(Event.COMPLETE, setFilter);
             var request:URLRequest = new URLRequest(imgUrl);
             loader.load(request);
             addChild(loader);
			 //-- min -100 and max 100 for  brightness
			 Br_slider = getSlider(-100, 100, 50, 390, 300);
			 //-- min -100 and max 100 for  contrast
		     co_slider = getSlider(-100, 100, 50, 420, 300);
			 //-- min -180 and max 180 for  hue
		     hu_slider = getSlider(-180, 180, 50, 450, 300);
			 //-- min -100 and max 100 for  saturation
		     sa_slider = getSlider(-100, 100, 50, 480, 300);

         }
		 private function getSlider(min, max, xx, yy, w){
		 	var slider:Slider = new Slider();
			    slider.minimum  = min;
			    slider.maximum  = max;
			    slider.x  = xx;
			    slider.y  = yy;
			    slider.width  = w;
				slider.addEventListener(Event.CHANGE, onChange);
				addChild(slider);
				return slider;
		 }

        public function onChange(e:Event):void {
			setFilter(e)
        }  

		private function setFilter(e:Event){
             var myColor:AdjustColor = new AdjustColor();
             myColor.brightness = Br_slider.value;
             myColor.contrast = co_slider.value;
             myColor.hue = hu_slider.value;
             myColor.saturation = sa_slider.value;
             var matrix:Array = new Array();
             matrix = myColor.CalculateFinalFlatArray();
             var filter:ColorMatrixFilter = new ColorMatrixFilter(matrix);
             var myFilters:Array = new Array();
             myFilters.push(filter);
             loader.filters = myFilters;
		}
     }
}

This code can be used to get complete list of children from DisplayObjectContainer

using the class

import druva.display.displayUtils
displayUtils.traceChildList(stage);

This is the actual class

package druva.display {

import flash.display.*;

public class displayUtils extends MovieClip
{
   public static function traceChildList(dispObj:DisplayObjectContainer, string:String = ""):void
   {
      for (var i:int = 0; i < dispObj.numChildren; i++)
      {
         trace(string + dispObj.getChildAt(i).name);
         if (dispObj.getChildAt(i) is DisplayObjectContainer)
            traceChildList(DisplayObjectContainer(dispObj.getChildAt(i)), string + "  ");
      }
   }
}
}

The below code shows how to use the class

import druva.NumberUtil;

trace(NumberUtil.ordinalise(1));//  1st
trace(NumberUtil.ordinalise(2));//  2nd
trace(NumberUtil.ordinalise(3));//  3rd
trace(NumberUtil.ordinalise(4));//  4th
trace(NumberUtil.ordinalise(111));//  3rd
trace(NumberUtil.ordinalise(113));//  4th

This is the actual class for validation

package druva{
	import flash.display.Sprite;

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

		public static function ordinalise(number:Number):String {
			var numS:String=String(number);
			var suffix:String;
			if (numS.substr(-2,2)!="13"&&numS.substr(-2,2)!="12"&&numS.substr(-2,2)!="11") {
				if (numS.substr(-1,1)=="1") {
					suffix="st";
				} else if (numS.substr(-1, 1) == "2") {
					suffix="nd";
				} else if (numS.substr(-1, 1) == "3") {
					suffix="rd";
				}
			}
			if (! suffix) {
				suffix ="th";
			}
			return numS+suffix;
		}

	}
}

The below code shows how to generate Random colors using Action Script

import druva.ColorUtils;
import flash.display.Graphics;
import flash.display.Sprite;
var box:Sprite = new Sprite();
var mc:MovieClip = new MovieClip();
addChild(mc);

function createBoxes(e:Event=null) {
	removeChild(mc);
	for (var i:Number=1; i<=10; i++) {
		box = new Sprite();
		box.graphics.beginFill(ColorUtils.randomColor());
		box.graphics.lineStyle(1, 0x000000);
		box.graphics.drawRect(0,0,30,30);
		box.graphics.endFill();
		box.y = 50;
		box.x = i*40
		mc.addChild(box);
	}
	addChild(mc);
}

createBoxes();

btnn.addEventListener(MouseEvent.CLICK, createBoxes);

You can also declare the same as protoType

package druva{
	import flash.display.Sprite;

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

		public static function randomColor():uint {
			var colArray:Array=new Array("0x");
			for (var i:Number=1; i<=3; i++) {
				colArray[i]=Math.floor(Math.random()*255-0+1)+0;
				colArray[i]=colArray[i].toString(16);
			}
			var uintN:uint=new uint(colArray.join(""));
			return uintN;
		}
		public static function generateColor():int {
   			return Math.ceil(Math.random() * 0xFFFFFF);
  		}
	}
}
