[OSM-talk] Attempt to make a map of a building floorplan

[Patrick Weber]

You will probably have more luck with the following application, which 
does the tile cutting you need:

Mapnik is not meant as a tile cutter, but renders data from a XML file, 
so I think it wouldnt be off much use for you.

Cheers
