The basic code looks good here. You don't say how it's not working.
One thing I did notice was that you set the Canvas size after you draw your
stuff - which probably isn't a great idea. Also generally you want to
turn off
Swing double buffering - otherwise Swing is likely to render all your
'vector'
data into an offscreen buffer and only that bufferedImage will be drawn
to the
SVGGraphics2D (which is what you wanted to do in your second message :).
