Performance Improvement for SVG Graphics

Hello,

I have a problem with inluding medium to large svg graphics into my pdf
documents. The performance in the generation process is pretty bad. I takes
considerably longer when I include a svg graphic compared to using for
instance a png. 

I have a lot of graphics which need to be scalable. 
It's mainly 3D stuff. Is there a better way for doing this or do the svg
graphics have to match a certain profile? The average file size is about
30k. 
The generation is done in a web apps. So it's kind of time critical.


cheers,
Pete

AW: Performance Improvement for SVG Graphics

Posted by Neumann Andreas <an...@karto.baug.ethz.ch>.

Hi,

SVG conversion in FOP is done through Batik, as far as I know.

It might be that the FOP version you use, uses a rather old version of Batik. The current SVN version performs better than the latest stable release.

Also, conversion depends on the contents of the SVG files.

I recently had performance problems too when using the svgrasterizer from Batik, which also generate PDF directly from SVG files. My SVG files had a lot of "opacity" attributes specified.

Thomas DeWeese (one of the Batik programmers) recommended to change the opacity to "fill-opacity" and/or "stroke-opacity". Indeed Batik performed much better with that change.
