There is no way at this time to know the length of a string in batik. Though
using the SVG DOM you are able know that information - it's a really really
complicated things to compute (depending of the style of the text element,
additional tspan, svg font, mixed system and svg font, filter...) and
the method is not supported yet.
The only thing you can do is dealing with Java2D API to compute the length of
a string for a particular font and consider that batik will display the
string using the same metrics (except that our work is done in 96dpi and
Java2D is in 72dpi).
Hope this helps,
Thierry.
