Hi

import flash.display.BitmapData;
System.security.allowDomain("http://www.helpexamples.com/flash/images/image2.jpg");
var mc:MovieClip = this.createEmptyMovieClip("mc", this.getNextHighestDepth());
var listenerObj:Object = new Object();
listenerObj.onLoadInit = function (target_mc:MovieClip):Void
{
    target_mc._x = (Stage.width - target_mc._width) / 2;
    target_mc._y = (Stage.height - target_mc._height) / 2;
    var myBitmapData:BitmapData = new BitmapData(mc._width, mc._height, false, 0xFF0000);
     trace(myBitmapData.getPixel(target_mc._x, target_mc._y).toString(16));
}
var image_mcl:MovieClipLoader = new MovieClipLoader();
image_mcl.addListener(listenerObj);
image_mcl.loadClip("http://www.helpexamples.com/flash/images/image2.jpg", _root.mc);

  First you can get pixel value inside onLoadInit and then try to draw rectangle

Otherwise you can try

hitTest Method

Hi

  You can create like this BitmapData and you can get

var myBitmapData:BitmapData = new BitmapData(100,100, false, 0xFF0000);
