GD assumed in this case that you wanted to render a single pixel, AGG will not make this assumption and skip the shape regards, thomas _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
