I have access to the mapnik source code. I see the code where it supports multiple polygon in a single shapefile record (by looking at the number of parts). But it appears to be then returning each part as a polygon in the larger mapnik::polygon_impl. Unless you are saying that the mapnik library understands the shapefile direction part and is not filling counter clockwise shapes (as defined by the shapefile definition)? - Brian _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
