Hello, I'm new to Mapnik-Users, and I have what might be a naive question about
the Python bindings layer.
Intermittently I get an error of the type:
Python argument types in
Color.__init__(Color, unicode)
did not match C++ signature:
__init__(_object*, std::string)
__init__(_object*, int, int, int)
__init__(_object*, int, int, int, int)
Request Method:GET
Request URL:
Exception Type:ArgumentError
Exception Value:Python argument types in
Color.__init__(Color, unicode)
did not match C++ signature:
__init__(_object*, std::string)
__init__(_object*, int, int, int)
__init__(_object*, int, int, int, int)
These occur when I pass a Python string that contains Unicode into the
Python-Mapnik bindings, as:
colordef = u'#FFFF00'
color = mapnik.Color(colordef)
I've been able to work around this on a case-by-case basis by wrapping the
Unicode strings in the string converter function:
colordef = u'#FFFF00'
color = mapnik.Color(str(colordef))
My question is, why isn't this conversion handled in the Python bindings layer
automatically?
