How to resize dynamically loaded Base64 Image?

Question

Hi all,
I'm currently writing a flex component which renders a
formular from a
xml definition file. I get the image as Base64 and decode it
whith some
flex internal methods.
private function addBgImage(base64Image:String):void{
var base64Decoder:Base64Decoder = new Base64Decoder();
base64Decoder.decode(base64Image);
var byteArray:ByteArray = base64Decoder.flush();
var loader:Loader = new Loader();
loader.loadBytes( byteArray );
var img:Image = new Image();
img.addChild(loader);
this.addChild(img);
This works fine. Now i want to resize the image, but nothing
works. I
tried:
img.width = 100;
img.maxWidth = 100;
img.explicitWidth = 100;
loader.width = 100;
But nothing works. Can somebody help me? Do I need to wait
till the
ByteArray is loaded?
Best regards,
Christian

solved.
solution:
I have to wait till the loader finished loading and then i
can resize the image in this method.
private var loader:Loader;
private function addBgImage(base64Image:String):void{
var base64Decoder:Base64Decoder = new Base64Decoder();
base64Decoder.decode(base64Image);
var byteArray:ByteArray = base64Decoder.flush();
loader = new Loader();
loader.loadBytes( byteArray );
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,
imgLoaded);
var img:Image = new Image();
img.addChild(loader);
this.addChild(img);
private function imgLoaded(event:Event):void{
loader.width = 100;
}
