在actionscript中获取图像原始宽度和高度

我在Flex 3中使用AS3来创建新图像,似乎无法获得原始图像的确切大小.percentHeight和percentWidth到100可以完成这项工作,但是ObjectHandlers中的限制要求我以像素为单位设置图像比例.

有解决方案吗

注意:这也适用于显示没有ObjectHandler控件的图像原始尺寸,只需删除那些不适用的行.

经过努力解决问题的时间后,我通过动作论坛找到了我自己的答案,事实上,只有一个解决方案,我很惊讶其他地方没有这样的话题.

private function init():void {
    var image:Image = new Image();
    image.source = "http://www.colorjack.com/software/media/circle.png";
    image.addEventListener(Event.COMPLETE, imageLoaded);
    /* wait for completion as Image control is asynchronous,
     * which mean ObjectHandler will attempt to load asap
     * and you are not able to get the correct dimension for scaling.
     * EventListener fixed that.
     */
    this.addChild(image);
    //whenever you scale ObjectHandler control, the image is always fit by 100%
    image.percentHeight = 100;
    image.percentWidth = 100;
}

private function imageLoaded(e:Event):void{
    var img:Image = e.target as Image;
    trace("Height ", img.contentHeight);
    trace("Width ", img.contentWidth);
    var oh:ObjectHandles = new ObjectHandles();
    oh.x = 200;
    oh.y = 200;
    oh.height = img.contentHeight;
    oh.width = img.contentWidth;
    oh.allowRotate = true;
    oh.autoBringForward = true;
    oh.addChild(img);
    genericExamples.addChild(oh);
}
