Question on getting BBox from an element in a doc

[Phil Wright]

So I have some <path> elements in my SVG document and I want to get the
bounding box.

I tried this (basically guessing at the procedure):

   public static Rectangle2D getPathBBox(SVGDocument doc, String name) {
       SVGRect rect;
       SVGOMPathElement pe;
       pe = (SVGOMPathElement)doc.getElementById(name);
       pe.setSVGContext(new SVGPathElementBridge());
       rect = pe.getBBox();
       return new Rectangle2D.Double(rect.getX(),rect.getY(),rect.getWidth
(),rect.getHeight());
   }

But it went boom:

   at org.apache.batik.bridge.AbstractGraphicsNodeBridge.getBBox(Unknown
Source)
   at org.apache.batik.dom.svg.SVGLocatableSupport.getBBox(Unknown Source)
   at org.apache.batik.dom.svg.SVGGraphicsElement.getBBox(Unknown Source)
   at SVGDocUtil.getPathBBox(SVGDocUtil.java:160)

Any help gratefully accepted.

    Phil
