How to improve SVG image quality in pptx-export

[jsc27]

Hello,

I am using a subreport with a SVG image in it (rendered with batik). If I only export the subreport in ppt, everything looks fine. If I export the main report, the svg image quality is poor (normal images are presented fine). Even SVG images directly on the main report have poor quality. Has to do something with the main report settings.

Tried to configure the net.sf.jasperreports.image.dpi property in the report settings in jasperstudio, but no luck.
When I export the report to PDF, everything looks fine (because PDF is able to render the svg image, powerpoint is not).

Any help/solution would be quite welcome.

Thanks!
