ByteArray 到 BitmapData AS3 [英] ByteArray to BitmapData AS3

问题描述

我正在使用 com.adobe.images.PNGEncoder 将 bitmapData 编码为 byteArray.有没有办法不使用 Loader 将 byteArray 转换回 bitmapData?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.

我不想使用加载器的原因是它是异步的，我不想实现事件监听器.

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

以下是使用加载器类但是是同步的.

The following is using the loader class but is synchronous.

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

编辑:别介意 loadBytes 也是异步的，文档说你需要等待 init 事件.不想要事件监听器的原因是什么?它们在 AS3 中很常见.

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.

所以你需要这样的东西:

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);
