GVT Tree and SVG DOM

[Hentschel Christian <Ch...@student.hpi.uni-potsdam.de>]

Hi,

I need to rasterize a single SVG DOM node. I thought transferring the SVG Document into a GVT Tree and render a single GVT Node by using its paint method might be a good idea:

UserAgent myUserAgent = new SVGAbstractTranscoderUserAgent();
GraphicsNode gvtRoot = new GVTBuilder().build(new BridgeContext(myUserAgent), document);

Unfortunately I didn't find a way of mapping back the GVT node to a SVG node - so if I get an arbitrary SVG node of the transferred Document - how may I find the corresponding GVT node out of the GVT Tree? Do both trees necessarily have an identical structure - that is: may I simply traverse the DOM tree until I reached the node  and apply the same path to the GVT Tree in order to get the corresponding GVT node? Is there a more clever way?
Thanks in advance,
christian

I think you can use bridgeContext eg:
- bridgeContext.getElement(graphicsNode); // get the SVG node by
supplying GVT Node
- bridgeContext.getGraphicsNode(svgElement); // get the GVT node by
supplying SVG Node
