Yes, sorry i did not respond sooner Manoj. The MarkersSymbolizer only supports these advanced features in Mapnik trunk (Mapnik2). Mapnik 0.7.x support is limited to blue arrows, whereas trunk has a number of new features as you can see on the wiki. > 2) Or is mapnik trunk (mapnik2) is really my only option.

The code is now becoming much more stable, so I think it is certainly viable to use. If you are using generate_tiles.py you may just need to upgrade the import statement from: import mapnik to import mapnik2 I am happy to answer any other specific questions you may have about Mapnik2. > In past(when it was 0.6.x), I always used the trunk, as it was (I thought!) > considered to have the most recent bug fixes and relatively stable.
