Hi Rolland,
The problem is that (ironically) the SVGGraphics2D doesn't support
output of complex
SVG gradients. You should file a bugzilla entry on this, but honestly I
don't know when we
would get to it. You might consider appending the source SVG to the
output document,
rather than depending on the SVGGenerator converting everything perfectly
(SVG is
a complex language and there are some things that don't map well).

> This issue is tested with the following configurations:
> - windowsXP jre1.4.2_08 with batik-1.5-fop-0.20-5.jar from
> http://www.ibiblio.org/maven/batik/jars/
> - windowwXP jre1.5.0_05 with batik-1.5-fop-0.20-5.jar from
> http://www.ibiblio.org/maven/batik/jars/
>
> I need to use this version of batik because of a later implementation of
> this svg file into a pdf report using fop and xslt.
>
>
> Do you have any idea where these varieties are coming from and how I can
> eliminate them?

> Best regards
