Description

I have tested this on Mac OSX 10.6 and on iOS, with the same results.
The values of scaleX and scaleY on a TransformGestureEvent (GESTURE_ZOOM) are always equal.
It can be easily seen by running the following code (Mac) and pinching on the group box:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="init()">
<fx:Script>
<![CDATA[
private function init():void{
Multitouch.inputMode = MultitouchInputMode.GESTURE;
zoomArea.addEventListener(TransformGestureEvent.GESTURE_ZOOM, function(e:TransformGestureEvent):void

{ if(e.phase==GesturePhase.UPDATE) scaleValues.text = e.scaleX+", "+e.scaleY; }

);
}
]]

</fx:Script>
<s:VGroup>
<s:Group id="zoomArea" width="500" height="300"/>
<s:Label id="scaleValues"/>
</s:VGroup>
</s:WindowedApplication>
