Dude you rock! Thanks!
Once the image complete loading I create a scale matrix, maintaining
the aspect ratio and then draw it to a new bitmap, then dispose of the
old data. Saves a ton of memory!
/********** CODE ************/
//When image loaded, create scaled bitmap
private function LoadComplete(evt:Event):void
{
evt.stopImmediatePropagation();
var loader:Loader = Loader(evt.target.loader);
var image:Bitmap = Bitmap(loader.content);
var sxy:Number = (image.width > image.height)?
(95/image.width):(95/image.height);
var scaleMatrix:Matrix = new Matrix();
scaleMatrix.scale(sxy,sxy);
var container:UIComponent = new UIComponent();
addChild(container);
var scaledImage:Bitmap = new Bitmap(
new BitmapData(95,95,true,0));
scaledImage.bitmapData.draw(image,scaleMatrix);
container.addChild(scaledImage);
contentLoader = null;
image.bitmapData.dispose();
}
