Oh man! I love RPG City Map generator, and I use an autotrace function in Serif Drawplus to transform the raster data into vector. I would LOVE a script that does it all automatically and produces a good vector result, particularly a clean two node line on diagonals. Unfortunately I don't use Linux. :: cries ::

Is there any chance you could make a version which runs on windows or is there some sort of emulator I can use to run your script on windows?

Can you post up sample SVGs of some of your results? I'd love to see how clean the results are.

Have some rep!
