Hello, If you mean that your map output is empty (an empty rectangle of your background colour) you may have the same trouble I had.
I the process looked a bit sensitive to projection. I could not have anything rendered if the shape files srs was different from map' srs, re-projection don't seemed to work. (In your case this would be your column in DB and maybe in geometry_column table too) I had to specify explicitly the srs for each layer and it has to be the same than map' srs. I don't have the exact methods names in head but this should look like, with your objects' names, : lyr1.set_srs(m.srs()); lyr2.set_srs(m.srs()); Hope it helps Nicolas. -- View this message in context: http://old.nabble.com/Rendering-map-through-c%2B%2B-API-tp27210929p27258602.html Sent from the Mapnik - Users mailing list archive at Nabble.com. _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
