If you build the GVT tree for the Document the you can ask any
batik.gvt.GraphicsNode for it's 'outline' which is a AWT Shape. Stroke
makes this a bit more complex of course (this can be accessed through
the ShapePainters on the GraphicsNode).
The Wiki has example code to build the GVT tree:

java.awt.Shape has two methods called 'getPathIterator'. One has a
'flatness' paramter, this one will only return move-to, line-to, and close
path commands (the line will deviate from the the true curve by no more
than the flatness parameter). The version without the flatness argument
will return the path potentially with cubic and quadradic path commands
as well.
You might want to use Google a little to explore problems before
posting (google is much quicker to respond that I am ;)
