I am not sure what your exact problems were, but we have had pretty good luck with the JSVGScrollCanvas. To zoom we simply do
AffineTransform transform = (AffineTransform)canvas.getRenderingTransform().clone(); double newScale = <<whatever>> transform.scale(newScale, newScale); scrollCanvas.setRenderingTransform(transform); The JSVGScrollCanvas we used was by Jan Lolling, which can be found in the Batik mail archives.
