推荐答案

当前 Web 浏览器的 JavaScript 和 DOM 实现并没有很好的机制来执行此类操作.

The JavaScript and DOM implementations of current web browsers don't really have good mechanisms for doing this sort of thing.

最好的办法是让 AS3 返回一个带有 base64 编码版本图像的 DATA 协议 URI.现代浏览器(IE8+、FF2+ 等)将接受 DATA URI 作为 IMG 标签的 SRC，并将呈现其中包含的图像.

Your best bet is to have your AS3 return a DATA protocol URI with a base64-encoded version of the image. Modern browsers (IE8+, FF2+, etc) will accept a DATA URI as the SRC of an IMG tag and will render the image contained therein.

您必须让 AS3 专家解释如何将字节数组转换为 base64 编码的字符串，但这并不难.

You'll have to have a AS3 expert explain how to turn an byte-array into a base64-encoded string, but it cannot be that hard.
