Re: How to render embedded png?

Please excuse my ignorance but I really cannot get a grip of this. Here is my
code, I can see svg, but no embed image. What is wrong? 
Thanks

        canvas = new JSVGCanvas();
        getContentPane().add(canvas);

        userAgent = new UserAgentAdapter();
        ctx       = new BridgeContext(userAgent);
        builder   = new GVTBuilder();
        try {
            // Parse the barChart.svg file into a Document.
            String parser = XMLResourceDescriptor.getXMLParserClassName();
            SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
            URL url = new URL(getCodeBase(), "embedData.svg");
            doc = f.createDocument(url.toString());

            svg = doc.getDocumentElement();


            NodeList l =
            svg.getElementsByTagName("image")     ;
            for (int i = 0; i < l.getLength(); i++)
            {
                Element n = (Element)l.item(i)   ;
                String image =
                        n.getAttributeNS(XMLConstants.XLINK_NAMESPACE_URI,
"href");
                String t = n.getAttributeNS(null, SVG_WIDTH_ATTRIBUTE);
                int width = Integer.parseInt(t);
                int height = Integer.parseInt(n.getAttributeNS(null,
SVG_HEIGHT_ATTRIBUTE));
                String id = "image" + Integer.toString(i);

                // Create and initialize the new image element
                Element imageElement =
doc.createElementNS(SVG_NAMESPACE_URI,
                        SVG_IMAGE_TAG);
                imageElement.setAttributeNS(null,
XMLConstants.XML_ID_ATTRIBUTE,
                        id);
                imageElement.setAttributeNS(null, SVG_WIDTH_ATTRIBUTE,
                        Integer.toString(width));
                imageElement.setAttributeNS(null, SVG_HEIGHT_ATTRIBUTE,
                        Integer.toString(height));
               
imageElement.setAttributeNS(XMLConstants.XLINK_NAMESPACE_URI,
XMLConstants.XLINK_HREF_QNAME,
                        "data::image/PNG;base64," +
base64Encode(image.getBytes()));
                doc.appendChild(imageElement);
                svg.removeChild(n);
            }
        } catch (Exception ex) {
        }
