AS3-放大图片？

Question

=)

So, I need to be able to zoom in on my image, but I cant get it to work properly.

I've got an Image showing my content, and it get it's content from a BitmapData.

The BitmapData is full-res, which is 2880x1620, and the Image is scaling to fit my window.

The SmoothImage is the same as Image, but with smoothing added.

<me:SmoothImage id="imageFull" visible="false" width="100%" height="100%" />

How would I go about zooming this image when I scroll my mouse?

This is the code I have, and it does change the scaling factor. But since it's set to fit my view, nothing happens...

        public function videoBufferWheel(event:MouseEvent):void{
            myZoom += (event.delta/10);

            if(myZoom >=1){
                imageFull.scaleX = myZoom;
                imageFull.scaleY = myZoom;
            }else{
                myZoom = 1;
            }
        }

It can not scaling because a element gets its maximum size (100%). You can increase this image only by set an attribute fillMode="clip".
