hotspot

Hi Klaus.
I want to make hotspot as pointer and labels. For this I use 2 of the hotspot

<hotspot name="pointer"
   url="myimage.jpg"
   ath="0" atv="0"
   width="100" height="30"
   align="left" edge="left"
   distorted="false"
/>
<hotspot name="Caption"
   url="textfield.swf"
   ath="0" atv="0"
   align="left" edge="left"
   autowidth="true" autoheight="true"
   html="Caption"
   ox="100"
/>

This works, but I need to do distorted="true". How do I replace the string ox="100"? Is this possible?

can give an example?
The problem in determining the size of the hotspot. When distorted="false" - the size of the hotspot constant. But when distorted="true" - the size of the hotspot is changing when you rotate the view.The problem to determine the new dimensions.
