Batik can not now what's the appropriate size as Peter mentions. This is due
to the use of percentages for example. If a rectangle has a width equals to
100% - what does it mean ?
You can let your outermost svg element with no width and height. By default
it means 100%, 100% and it's up to the user agent to choose the size. The
JSVGCanvas chooses the size of the component (depending on the layout manager
and the size of your application). The transcoder has 400,400 (which is
totally arbitrary) but you can set the default size using a transcoding hint.
Hope this helps,
Thierry.
