Thanks for all your help on this. To answer your question Alex, no
we are not using JPEGEncoder in our app, that was just to do a test
that could easily get us the ByteArray data that we know is a valid
image.
I will try the listener approach. I guess I thought that wouldn't be
needed since the data is already loaded.
Regardless, to get it working in the meantime we sent everything
thing back from the server as base64 encoded. We then used a
Base64Image class (which extends Image) to display the image.
http://flexlib.googlecode.com/svn/trunk/src/flexlib/controls/
Base64Image.as
(You will see it uses the same approach as yours to load the ByteArray)
It works very well and makes me think that it could be a model for
extending the Image component to receive a ByteArray as a source. It
really should be that easy!
Thanks for your thoughts.

Yes, that would be nice!
For what I’ve been doing a synchronous “convertToBitmapData
(bytes:ByteArray):BitmapData” would be really nice as well.
If only because using a “loader” seems a bit “wrong” when you’ve
already loaded (or otherwise have) a byteArray.
I have to admit that I’ve not actually checked the source code to
see if I could find/copy that kind of function, however, since I do
now have everything working with loader.
Thanks Alex!
Jim.

Yeah, things are “working”, but really there should be a loadBytes
() API on mx:Image/SWFLoader to save you a step.

Oops, sorry, this one makes slightly more sense (first thing in the
morning, not even finished my first cuppa…)
private var _ldr:Loader
private function myTest():void{
//get ByteArray from Image Component content
var testBM:Bitmap = testImg.content as Bitmap;
var myByte:ByteArray = new JPEGEncoder().encode(testBM.bitmapData);
_ldr = new Loader();
_ldr.contentLoaderInfo.addEventListener(Event.COMPLETE,bitmapLoaded);
_ldr.loadBytes(myByte);
}
private function bitmapLoaded(event:Event)
{
_ldr.removeEventListener(Event.COMPLETE,bitmapLoaded)
//reset source
myImage.source = _ldr.content;
}
.
