[flexcoders] ByteArray / URLLoader / Loader / Image / Size?

[Andrew D. Goodfellow]

(I have searched for this answer on the list and in the docs and can't find
anything so I'm gonna go ahead and post. If I missed a previous post, I
apologize, please point me towards it.)

I have an image in a ByteArray and I want to display it within a specific
width and height inside an Image object. Here is my logic:

private var urlloader:URLLoader = new URLLoader();
private var loader:Loader = new Loader();

urlloader.dataFormat = URLLoaderDataFormat.BINARY;
urlloader.data = ByteArray(imageByteArray);
loader.loadBytes(ByteArray(urlloader.data));
var child:DisplayObject = previewImage.addChild(genericLoader);

<mx:Image scaleContent="true" height="260" width="215" id="previewImage"/>

When it displays it does not scale automatically, it simply displays at 1:1
of the original ByteArray image. If I set child.width and child.height to
specific values (i.e. 215x260) the Image (or child) just doesn't display.

I CAN change scale directly or use a Matrix to scale it, but the problem
there is that the child.width and .height are returning 0 so I can't
calculate the correct scale.

Any ideas???
