我用com.adobe.images.PNGEn codeR为en code位图数据为ByteArray。有没有办法不使用装载机的ByteArray转换回位图数据？谢谢。

I'm using com.adobe.images.PNGEncoder to encode bitmapData to a byteArray. Is there a way to convert the byteArray back to bitmapData NOT using a Loader? thanks.

编辑：我不想使用Loader的原因是它是异步的，我不希望实施EventListeners的

the reason i don't want to use a Loader is it being Asynchronous, and I don't want to implement eventlisteners.

推荐答案

在使用装载机类，但同步以下。

The following is using the loader class but is synchronous.

var loader:Loader = new Loader();
loader.loadBytes(byteArray);
bmpData.draw(loader);

修改：没关系的loadBytes是异步过，文件说，你需要等待init事件。什么是不希望事件侦听器的原因是什么？他们是在AS3一个pretty的通行做法。

Edit: Nevermind the loadBytes is asynchronous too, the documentation says you need to wait for the init event. What is the reason for not wanting event listeners? They are a pretty common practice in AS3.

所以，你需要的东西是这样的：

So you need something like this :

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.INIT, function(e:Event):void {
   bmpData.draw(loader);    
});
loader.loadBytes(byteArray);
