Wonder how to apply smoothing, read and write pixels on a image loaded from a different domain name?

Quite simple, load as binary first and than load the ByteArray as Bitmap.


var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
urlLoader.addEventListener(Event.COMPLETE, urlLoaderComplete);

var url:String = "http://www.adobe.com/images/shared/product_mnemonics/50x50/flash_player_50x50.gif";
urlLoader.load(new URLRequest(url));

function urlLoaderComplete(e:Event):void
{
  var loader:Loader = new Loader();
  loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
  loader.loadBytes(urlLoader.data as ByteArray);
}

function loaderComplete(e:Event):void
{
  var bmp:Bitmap = e.currentTarget.content as Bitmap;
  addChild(bmp);
  var bitmapData:BitmapData = bmp.bitmapData
  bitmapData.applyFilter(bitmapData, bitmapData.rect, new Point(0, 0),
    new ColorMatrixFilter([
      0, 0, 0, 0, 0,
      1, 1, 0, 0, 0,
      0, 0, 1, 0, 0,
      0, -1, -1, 1, 0
  ]));
}
