Hi Bruno, and thanks for your help.
I got my original error cleared using your help, but did something also
change about appending point styles to the map?
dotsymbolizer = mapnik2.PointSymbolizer(mapnik2.PathExpression(
'dots/purpledot.png'))
dotsymbolizer.allow_overlap = True
dotsymbolizer.opacity = 0.5
partnerdotstyle = mapnik2.Rule()
partnerdotstyle.symbols.append(dotsymbolizer)
m.append_style('Partner Dot Style',partnerdotstyle)
Results in:
File "partnermapnikbasic.py", line 59, in <module>
m.append_style('Partner Dot Style',partnerdotstyle)
Boost.Python.ArgumentError: Python argument types in
Map.append_style(Map, str, Rule)
did not match C++ signature:
append_style(mapnik::Map {lvalue}, std::string style_name,
mapnik::feature_type_style style_object)
I don't see what I'm missing. (line 59 is the m.append_style line)
Thanks,

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)

Am I missing something silly?
