package
{
    import flash.display.Sprite;
    import flash.display.Loader;
    import flash.events.Event;
    import flash.net.URLRequest;
    import flash.display.*;
    import fl.transitions.easing.*;
    import fl.transitions.Tween ;
    public class BitmapLoader extends Sprite
    {
        private var _loader:Loader = new Loader( );
        var imgmc:MovieClip = new MovieClip();
        public function BitmapLoader ( )
        {
            addChild (imgmc);
            var loadcont:LoaderContext = new LoaderContext();
            _loader.contentLoaderInfo.addEventListener (Event.COMPLETE , onComplete);
            _loader.load (new URLRequest("c_m.jpg"));
        }
        public function onComplete (event:Event):void
        {
            var loadedImage:Bitmap = Bitmap(_loader.content);
            var bitmap:BitmapData = new BitmapData(loadedImage.width , loadedImage.height);
            bitmap.draw (loadedImage);
            var image:Bitmap = new Bitmap(bitmap,"auto",true);
            imgmc.addChild (image);
            new Tween(imgmc,"scaleX",None.easeIn,1,1.5,2,true);
            new Tween(imgmc,"scaleY",None.easeIn,1,1.5,2,true);
        }
    }
