I don't think I fully understand what you are asking for. But it
sounds like you want to put SVG icons over a very high resolution
image. If your High resolution image is done using RenderableImage
(say from JAI). You should be able to fairly easily construct a
single SVG document that has that image in the background (by
extending the image tag: see extending Batik on our web site). And
then has a bunch of use's or what ever to place the icons over the
image. This would have JSVGCanvas display everything (instead of a
JSVG canvas per icon).
Alternatively, You can build the GVT tree (either use the
JSVGCanvas since it has a really simple interface or look at the
Slideshow application: ...batik.apps.slideshow) and ask the GVT tree
(batik.gvt.GraphicsNode) for it's RenderableImage
(getGraphicsNodeRable, this returns a Filter but that just extends
java.awt.image.renderable.RenderableImage with a few extra methods).
You can then call createRendering with an appropriate RenderContext to
get proper renderings.

Hope the above is helpful.
