onZoom in Java code

I need to have some Java code executed when my picture is zoomed.

Is there any way to be notified on zoom in Java? (My client is not
interested in any scripting in the SVG so it must be done in the app.)

Thanks Thomas,

JGVTComponentListener was just what I needed...after I understood it.

     You can register a DOM event listener for 'onzoom' events (also
'onscroll' or 'onresize').

     You can also register a batik.swing.gvt.JGVTComponentListener
with the JSVGCanvas.  This get's called when the component's transform
changes.

     You can take a look at batik.swing.svg.JSVGComponet it registers
one so it can trigger the DOM events.
