Hi, I'm seeing a consistent rendering bug with this shapefile: http://teczno.com/oakland-beats.tar.gz
The problem is that there's at least one polygon in there that mapnik consistently draws twice. It's beat #06X, you can see the way it's overdrawn twice here: http://oakland.crimespotting.org/beat/06X ...in comparison to one that's not: http://oakland.crimespotting.org/beat/04X Note the darker edge; I've confirmed this with semi-opaque polygons as well. I've confirmed with ogrinfo and QGIS that the shape for 06X contains a closed polygon with the expected 16 vertices, and that there's only one such polygon in the file. I'm running mapnik from trunk, and my styles contain only the dotted lines seen above; the roads and so forth in those images are just tiles from Microsoft VEarth. Any thoughts? -mike. ---------------------------------------------------------------- michal migurski- m...@stamen.com 415.558.1610 _______________________________________________ Mapnik-users mailing list Mapnik-users@lists.berlios.de https://lists.berlios.de/mailman/listinfo/mapnik-users
