[OSM-talk] osmarender SVG in .Net

[Thom Shannon]

batik really doesn't want to work, I can render out a small svg with 
about half a dozen streets on it, but anything bigger and I get 
IllegalPathStateException from batik-rasterizer.jar, details below. I'm 
guessing there is an object somewhere near the middle of liverpool that 
is messed up.

Converting output.svg to C:\osm\output.png ...
