如何获得嵌入式图像/ swf的大小？(How to get the size of an embedded image / swf?)

 通常情况下，如果您从URL加载图像，您可以执行以下操作： 
 
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，如果将源设置为嵌入式图像类，则完整的事件不会触发。 所以我的问题是，如何获得嵌入式图像/ 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?
