I suggest your renderer look something like this. You'll see use of
dataChange and how to center the image. I don't have a proxy example,
but that's a good topic for a blog article someday...
Can you post two image swfs that don't center correctly? I want to make
sure those swfs are aligned to topleft otherwise this centering code
won't work for you.
<mx:Canvas dataChange="mediaObject= data as MediaElement">
<mx:Script>
private var _mediaObject:MediaElement;
[Bindable("mediaObjectChanged")]
public function get mediaObject():MediaElement
{
return _mediaObject;
}
public function set mediaObject(value:MediaElement):void
{
_mediaObject = value;
dispatchEvent(new Event("mediaObjectChanged");
}
private function centerImage():void
{
img.x = (width - img.measuredWidth) / 2;
img.y = ???
}
</mx:Script>
<mx:Image id="img" source="{mediaObject.imgSrc}"
complete="centerImage()" />
...
HTH,
-Alex

I don't know what this means. I haven't found any documentation that
refers to this (and believe me I have spent literally hundreds of
hours combing the Flex documentation). Could you point me to a
reference so I can get more information?

OK, bear with me as I go through this in pseudocode:
on mediaObjectChange
set img control to 100%
measure content
set img control from 100% to size of content
determine where top left of img control needs to be for img to
appear centered
set x and y of img
Yes?

Is there an example proxy swf available for download? You know, I
just realized I probably can't stop these movies anyway, since they
are nested and the designer forgot to put the stopAllClips() function
in most of them. Oh, well.
