Thanks for the reply.
Is there anyway I can keep my existing code which imports my stylesheet,
which is -
ProcessingInstruction pi =
doc.createProcessingInstruction("xml-stylesheet","C:\svg\style.css");
doc.insertBefore(pi, doc.getDocumentElement());
I don't quite see why this is picked up ok in the browser and renders the
SVG fine, but the stylesheet is not found when I choose to export the file
to JPG using the transcoder classes.
Thanks in advance again for any help,
Regards,
Dylan.

Correct, most likely Batik can't find your CSS style sheet. Commonly
this is cause by using a relative reference when a Document without a
knowable base url is used. In this case the problem is that you haven't
properly set the xlink:href attribute:
> css.setAttributeNS(null, "xlink:href",
> "http://localhost:7001/SVGWeb/style.css";);
This needs to be:
String XLINK_NAMESPACE_URI = "http://www.w3.org/1999/xlink";;
css.setAttributeNS(XLINK_NAMESPACE_URI , "xlink:href",
"http://localhost:7001/SVGWeb/style.css";);
Assuming you have an HTTP server on local host at port 7001
with a document at that location...
