Loading an Image from a local File (AIR/Flex)

Question

var f:File = (assume it's a valid image file reference)
var i:Image = new Image();
i.source = f.nativePath;
Kinda makes sense right? Except it doesn't display properly when the image is added unless I also specify a width and height on the new Image. This may not be a problem in many applications that hard code the size anyway, but I want to use the actual size of the image, without rescaling.
i.width = whatever;
i.height = whatever;//But I don't want to hard code these values, I want "actual" image size!
Anyone know of a way to get around this problem? Am I missing a step here? Web resources on this specific topic are very lacking.

Answer 1

I would think that this crummy custom Image class hack would work, but surprise surprise -- the width/height in loaderInfo is flat out WRONG when the event fires. It seems to have a hard coded width/height no matter what the file size. Silly!
<mx:Image xmlns:mx="http://www.adobe.com/2006/mxml" initialize="init()">
     <mx:Script>
          <![CDATA[
               public function init():void {
                    this.addEventListener(Event.COMPLETE, loaded);
               private function loaded(e:Event):void {
                    this.width = this.loaderInfo.width;
                    this.height = this.loaderInfo.height;
          ]]>
     </mx:Script>
</mx:Image>
Turns out, this version DOES work (but it's still a hack fix in my opinion):
<mx:Image xmlns:mx="http://www.adobe.com/2006/mxml" initialize="init()">
     <mx:Script>
          <![CDATA[
               public function init():void {
                    this.addEventListener(Event.COMPLETE, loaded);
               private function loaded(e:Event):void {
                    this.width = this.contentWidth;
                    this.height = this.contentHeight;
          ]]>
     </mx:Script>
</mx:Image>
You guys at Adobe are so silly.    It would seem to me that Image's width and height should be set (rather than left at 0) once the content's width and height is known.  So now that I've fixed this bug (as far as I'm concerned) for ya Adobe, I take cash, cashier's check, or money orders--thanks!
But really, if this doesn't work this way in Flex 4, I think it should.
