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) {
}
