Hi Ryan,
Although Batik most certainly supports radial gradients, I'm not sure that
support currently extends to the SVGGraphics2D arena. You can likely add
support for it quickly though by extending DefaultExtensionHandler and
overriding the handlePaint method...something like this...
public class RadialGradientPaintExtensionHander extends
DefaultExtensionHandler {
@Override
public SVGPaintDescriptor handlePaint(Paint paint, SVGGeneratorContext
svggc) {
if(paint instanceof RadialGradientPaint) {
// create svg radial gradient dom elements
...
// return an extension of SVGPaintDescriptor appropriate for
this radial gradient
}
return null;
}
}
You can also use the dom directly and then transcode the resulting document,
but that is an entirely different approach.
Hope this helps,
jonathan
