Question

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。 %Height＆amp; 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。

任何解决方案？

Answer 1

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。

经过努力解决方案后，我通过动作论坛找到了自己的答案，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);
}
