Hi Cameron Thanks for your quick reply.
Your latest code correctly adds the pi before the SVG node. However, it appears that the elements that were added through the DOMGroupManager are no longer being written out. DOMTreeManager dtm = svgGen.getDOMTreeManager(); DOMGroupManager dgm = new DOMGroupManager(new GraphicContext(), dtm); dgm.addElement(imageElement); this used to work. Any ideas what could be the cause?

The SVGGraphics2D object will just copy over the document element from the generated SVG tree to be serialized. You could, as well as the other changes I mentioned, change the line in SVGGraphics2D.stream(Element, Writer, boolean) that says this: svgDocument.appendChild(svgRoot); with this: if (rootParent == null) { for (Node n = svgRoot.getOwnerDocument().getFirstChild(); n != null; n = n.getNextSibling()) { int t = n.getNodeType(); if (t == Node.ELEMENT_NODE) { svgDocument.appendChild(n); } if (t == Node.PROCESSING_INSTRUCTION_NODE) { svgDocument.appendChild(n.cloneNode(false)); } } } else { svgDocument.appendChild(svgRoot); } It's a bit hackish, but should work. If you were serializing only a subtree of the generated document, though, the PIs wouldn't get written out. (But I'm not sure that you would want them there anyway.)
