Michael,
constructor of PointSymbolizer in Mapnik 2.0 no longer has the parameters "type", "width", "height".
See this page for other changes.

Assunto: [Mapnik-users] Point Symbolizer mystery
Hi all:
I'm running mapnik2, and doing find, until I try to add a
PointSymbolizer in Python.
dotsymbolizer =
mapnik2.PointSymbolizer('/Users/semchie/Documents/GIS/dots/purpledot.png',
'png', 16, 16)
dotsymbolizer.allow_overlap = True
dotsymbolizer.opacity = 0.5
partnerdotstyle = mapnik2.Rule()
partnerdotstyle.symbols.append(dotsymbolizer)
When I run the script, I get:
Traceback (most recent call last):
File "mapnikgridtest.py", line 48, in <module>
dotsymbolizer = mapnik2.PointSymbolizer('/purpledot.png', 'png',
16, 16)
Boost.Python.ArgumentError: Python argument types in
PointSymbolizer.__init__(PointSymbolizer, str, str, int, int)
did not match C++ signature:
__init__(_object*,

Am I missing something silly?
Thanks,
