Get image original width & height in actionscript

Question

I use AS3 in Flex 3 to create new image and seem unable to get the exact size of the original image. percentHeight & percentWidth to 100 can do the job, but limitation in ObjectHandlers require me to set the image scale in pixel.

Any solution?

Answer 1

Note: this is also applicable for displaying Image original dimension without ObjectHandler control, just remove those lines that are not applicable.

After struggle hours for solution, I found my own answer thru in actionscript forum, in fact, only one solution, I surprise there was no such topic elsewhere.

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);
}
