Ok clear enough...

I guess I don't understand where the screenshot comes in, above it
sounded like you were using the SVGGraphics2D to convert the contents
of your JInternalFrame to SVG.

I sounds like the SVG you are feeding to the rasterizer isn't set
up properly. In particular you may want to set the viewBox attribute
on the outermost SVG element (to something like: "0 0 600 800"). You
might also set the width and height on the outermost SVG element. I
believe if you used the SVGGraphics2D it should do this for you (not
100% certain).

The transcoder does understand clipPath info the problem is that
something is telling the transcoder the wrong region of the image to
rasterize.
KN> Do I overlook something?
I suspect you need to add the viewBox attribute on your outermost
SVG element.
