How can we use as3 to stretch images?

Hi Tom,

I'm not sure if this would do it for you, and I don't know how to use the mouse wheel as a programmatic input device -- never done that before.

But, I'd make the image as a MovieClip (MC): call it mainImage.  I'd make another graphic object as MC that acts a "dragging handle,": call it draggingHandle.

I'd put draggingHandle on top of the edge of mainImage.

This code should work:

var mainImageOrigWidth = mainImage.width;

draggingHandle.addEventListener(MouseEvent.MOUSE_DOWN,startDragging);
draggingHandle.addEventListener(MouseEvent.MOUSE_UP,stopDragging);

function startDragging(e:MouseEvent):void{
	draggingHandle.startDrag();
}

function stopDragging(e:MouseEvent):void{
	mainImage.scaleX = (draggingHandle.x - mainImage.x) / mainImage.width;
	draggingHandle.stopDrag();
}
