<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

<mx:Rotate id="rotate"

target="{img}"

angleFrom="0"

angleTo="360"

duration="1000"

originX="{imgOriginX.value}"

originY="{imgOriginY.value}" />

<mx:ApplicationControlBar dock="true">

<mx:Form styleName="plain">

<mx:FormItem label="originX:">

<mx:NumericStepper id="imgOriginX"

minimum="0"

maximum="{img.width}"

value="0" />

</mx:FormItem>

<mx:FormItem label="originY:">

<mx:NumericStepper id="imgOriginY"

</mx:FormItem>

<mx:FormItem>

<mx:Button label="Rotate"
