Question

怎么样把我创建的MovieClip转换为Bitmap?

var mc:MovieClip = new MovieClip();
loadImg.load(new URLRequest(img.@src));//加载图片
mc.addChild(loadImg);
var bp:Bitmap = (mc.content as Bitmap);

我这样写死都不得

Answer 1

//要加裁完成后才能设置，Loader类才有content,MovieClip没有，改成下面的
var mc:MovieClip = new MovieClip();
var bp:Bitmap;
loadImg.load(new URLRequest(img.@src));//加载图片
mc.addChild(loadImg);
loadImg.contentLoaderInfo.addEventListener(Event.COMPLETE,comPleteHandler);
function comPleteHandler(e:Event) {
bp = (loadImg.content as Bitmap);
}

这个问题好象在哪见过
