ByteArray to Sprite

Question

Hi   I'm having problems with having my bytearray (which is an image) drawn into a sprite. This is my attempt so far:
var imgB:BitmapData = new BitmapData(271, 278, true, 0xff0000);
imgB.setPixels(new Rectangle(0,0,271,278), $imgData);
$image.graphics.beginBitmapFill(imgB,new Matrix(), false, true);
My byteArray is $imgData, and the sprite that I want to draw to is $image. When I run the above code I get EOF error:
Error: Error #2030: End of file was encountered.      at flash.display::BitmapData/setPixels()
Any thoughts?  Thank you

I'm not sure what you're trying to do here...but you cannot use the binary data you loaded with a URLLoader as bitmapData if it was loaded from a png or jpeg for example. Those file formats need to be decoded into bitmapData - using the player's native support for that seems best.
There does seem to be a frame delay with the loadBytes method and you can't catch it using the COMPLETE event, as you say.
I got it working like this (perhaps there is a better way than using the enterFrame, but I just did this quickly to check)
var $image:Sprite=new Sprite();
addChild($image);
var myBitmapData:BitmapData;
var imageLoader:Loader = new Loader()
var dataLoader:URLLoader=new URLLoader();
dataLoader.dataFormat = flash.net.URLLoaderDataFormat.BINARY
dataLoader.addEventListener(Event.COMPLETE,completeHandler)
function loadImage(url:String):void{
    var req:URLRequest=new URLRequest(url);
    dataLoader.load(req)
function completeHandler(e:Event):void{
    //use enterFrame to check for loaded content
    imageLoader.addEventListener(Event.ENTER_FRAME,imageDecodeHandler);
    imageLoader.loadBytes(e.currentTarget.data);
function imageDecodeHandler(e:Event):void{
    if (imageLoader.content) {
        trace('loaded')
        imageLoader.removeEventListener(Event.ENTER_FRAME,imageDecodeHandler);
        myBitmapData = Bitmap(imageLoader.content).bitmapData;
        //imageLoader.content width and height available now as well as myBitmapdata.rect etc
        $image.graphics.beginBitmapFill(myBitmapData,null,true,true);
        $image.graphics.drawRect(0,0,stage.stageWidth,stage.stageHeight);
        $image.graphics.endFill()
    } else {
        trace('not yet loaded')
//substitute a local image file here:
loadImage("46.png")
