如何获取嵌入图像/swf 的大小？
通常，如果您从 URL 加载图像，您将执行以下操作：
m_image = new Image();
m_image.addEventListener(Event.COMPLETE, image_completeHandler, false, 0, true);
m_image.source = "http://www.example.com/image.jpg";
private function image_completeHandler(event:Event):void
{
// Image content has now loaded, we need to wait for it to validate it's size
m_image.addEventListener(FlexEvent.UPDATE_COMPLETE, image_updateCompleteHandler, false, 0, true);
}
private function image_updateCompleteHandler(event:FlexEvent):void
{
// Do stuff with width / height
}
但是，如果您将源设置为嵌入图像类，则完整事件似乎不会触发。 所以我的问题是，如何获得嵌入图像/swf 的宽度/高度？
Normally if you were loading an image from a URL you would do the following:
m_image = new Image();
m_image.addEventListener(Event.COMPLETE, image_completeHandler, false, 0, true);
m_image.source = "http://www.example.com/image.jpg";
private function image_completeHandler(event:Event):void
{
// Image content has now loaded, we need to wait for it to validate it's size
m_image.addEventListener(FlexEvent.UPDATE_COMPLETE, image_updateCompleteHandler, false, 0, true);
}
private function image_updateCompleteHandler(event:FlexEvent):void
{
// Do stuff with width / height
}
But, if you set the source to an embedded image class, the complete event doesn't appear to fire. So my question is, how can you get the width / height of an embedded image / swf?

任何嵌入式资源的启动都是同步的（我认为唯一的例外是 Loader.loadBytes），因此一旦执行此操作，您就可以访问其所有属性：
The instatiation of any embedded asset is syncronous (I think the only exception is Loader.loadBytes), so as soon as you do it you can access all its properties:
