I need a tool to rasterize svg's to png's to run some server side tasks. I've found batik to work pretty well on my windows machine and there are many cool features. however, when i run it on my unix server i get:

[landon.silla@mordor ~]$ java -jar ~/temp3/batik-1.7/batik-rasterizer.jar ~/mrv_basemap.svg
About to transcode 1 SVG file(s)

i did some digging and found that my machine is headless and i need a x11 tool. I don't really know what that means other than it deals with outputting graphics to a monitor. (my server obviously doesn't have/need one). the tutorials to install x11 to fix headless seem a bit over my head. and the source for batik is rather extensive, so i don't want to spend loads of time to learn the code just so i can modify it.

can anybody help me fix this error so i can run the command given above on my unix server?
