Hi, I'm new to Mapnik having taken over a project from a colleague who has left our firm. I'm picking things up OK and have been successfully editing the Mapnik XML for our maps.
I have just hit my first technical issue with Mapnik. When rendering a region with donut holes in it, the holes are ignored and the complete area is filled by a a <PolygonSymbolzer>. I've checked the data in the PostGIS database and using ST_NumInteriorRings<http://postgis.refractions.net/docs/ST_NumInteriorRings.html>does still return the current number of interior rings/donut holes. Any ideas on what's happening? A Mapnik bug or something wrong with the data? Cheers, Bud
