In Flash, the BitmapData object can be used to store bitmaps in RAM, you can later draw them to a MovieClip using the beginBitmapFill() method.
How do you load an ex
taking from cotton and will, this will display the bitmap after it is loaded:
import flash.display.Bitmap;
import flash.display.BitmapData;
var bitmapData:BitmapData;
var bmVis:Bitmap;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
loader.load(new URLRequest("put url here"));
function onComplete (event:Event):void
{
trace("loaded!");
bitmapData = event.target.content.bitmapData;
bmVis = new Bitmap(bitmapData);
this.addChild(bmVis);
}
