Question

How can I copy or duplicate the bitmapdata from a mx:image component?

I need to display the same image in multiple screens of my application and don’t want to have to download the image multiple times.

I could just use a urlrequest to download the image as a bitmap and copy that but I like the way you can can just set the source of the image component.

Image extends SWFLoader which has a content property that will contain the Bitmap object that was loaded. Wait for the image to load, cast the content to Bitmap and read its bitmapData

public function imageLoadCompleteHandler(e:Event):void
{
    var bitmap:Bitmap = img.content as Bitmap;
    if(bitmap == null) {
        trace("loaded content is not an image");
        return;
    }
    bmpData = bitmap.bitmapData;
    //hurray..!
}
