Is The SVGLocatable interface is not defined by Apache Batik, but rather by the W3C (similar to the DOM interfaces such as org.w3c.dom.Element, etc.). The package name is org.w3c.dom.svg. Batik 1.6 included Javadoc for this package, not sure if 1.7 does. > I'm a little confused about this part of the code you provided: > > ((SVGLocatable)node).getBBox(); > > I know that you are calling the getBBox() method of an interface that > implements the SVGLocatable interface.

The node is of type SVGElement (or some subclass thereof). The cast is required in my code because I don't know a more precise type. If you do, e.g., you have a SVGRectElement or something, then no cast would be necessary. Using the normal DOM API's, you get SVG stuff. E.g., if you say x = document.getDocumentElement() then you can rest assured that "x" is an SVGElement. -Archie -- Archie L. Cobbs
