Hi,
For a project I'm working on, I got around the lack of dynamic updates
in Batik-1.1 by manually creating my SVGDocument with a new colour every
time new colour was chosen.
In my case the colours were prechosen by the user, and all I had to do
was to create a number of SVGs, render them into PNGs and then display
them.
This is basically all I did, (with some other gunk missing).
Dont know if this helps :)
//
//
//
public class NewIcon
{
//
DOMImplementation impl = SVGDOMImplementation.getDOMImplementation
();
String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
Document doc = impl.createDocument (svgNS, "svg", null);
// Elements
Element svgRoot = doc.getDocumentElement ();
Element circle = doc.createElementNS (svgNS, "circle");
Element line1 = doc.createElementNS (svgNS, "line");
public NewIcon (String strColor)
{
// Set attributes
circle.setAttributeNS (null,"style", "stroke-width: 2.5; stroke: "
+ strColor);
circle.setAttributeNS (null, "cx", Integer.toString (32));
circle.setAttributeNS (null, "cy", Integer.toString (25));
circle.setAttributeNS (null, "r", Integer.toString (12));
svgRoot.appendChild (circle);
}
public SVGDocument getDocument ()
{
return (SVGDocument)doc;
}
public ImageIcon SVGtoImage (SVGDocument svgDoc)
{
ImageIcon iconTemp = null;
PNGTranscoder t = new PNGTranscoder ();
ByteArrayOutputStream byteOut = new ByteArrayOutputStream ();
t.addTranscodingHint(PNGTranscoder.KEY_XML_PARSER_CLASSNAME,
"org.apache.crimson.parser.XMLReaderImpl");
t.addTranscodingHint(PNGTranscoder.KEY_WIDTH, new Float(64));
t.addTranscodingHint(PNGTranscoder.KEY_HEIGHT, new
Float(80));
// create the transcoder input
try
{
TranscoderInput input = new TranscoderInput(svgDoc);
TranscoderOutput output = new TranscoderOutput(byteOut);
t.transcode(input, output);
// flush and close the stream then exit
byteOut.flush ();
byteOut.close ();
// now byteOut contains the raw image data
iconTemp = new ImageIcon (byteOut.toByteArray ());
//iconTemp.setImage (imageTemp);
}
catch (Exception e)
{
e.printStackTrace();
}
return iconTemp;
}
}
