forceSmoothing property
To smooth dynamically loaded bitmaps:
[cc lang="actionscript"]
var mcl:MovieClipLoader = new MovieClipLoader();
var mclObj:Object = new Object();
mcl.addListener(mclObj);
mcl.loadClip(“path/to/image”, clipToLoadImageIn);
mclObj.onLoadInit = onLoadInit;
function onLoadInit(theLoadedImage:MovieClip)
{
theLoadedImage.forceSmoothing = true;
}
[/cc]
