Well I've gotten a little farther, but now I'm getting new errors.
When I hit the refresh button, I store a copy of the current rendering
transform. I call setDocument() on the JSVGCanvas. Then I wait for the
GVT tree to finish rendering
(GVTTreeRendererAdapter.gvtRenderingCompleted()). After that's
finished, I set the rendering transform back and get the following
error:
java.awt.image.RasterFormatException: (x + width) is outside raster
at
sun.awt.image.IntegerInterleavedRaster.createWritableChild(IntegerInterl
eavedRaster.java:450)
at org.apache.batik.gvt.renderer.DynamicRenderer.repaint(Unknown
Source)
at org.apache.batik.gvt.renderer.StaticRenderer.repaint(Unknown
Source)
at org.apache.batik.swing.gvt.GVTTreeRenderer.run(Unknown
Source)
Any ideas?

hi, michael --
if you look at the code for the "zoom", "pan" and "rotate" interactors
that come with JSVGCanvas, you'll discover that what they change is
the canvas's "rendering transform". so, if you can preserve that
when you update your SVG document, then you will preserve the effects
of any previous zoom/pan/rotate's that the user executed...
