Class Projection

__getinitargs__( (Projection)arg1) -> tuple :

    C++ signature :
        boost::python::tuple __getinitargs__(mapnik::projection)

__init__( (object)arg1 [, (str)proj4_string]) -> None :
    Constructs a new projection from its PROJ.4 string representation.
    
    The parameterless version of this constructor is equivalent to
       Projection('+proj=latlong +ellps=WGS84')
    
    The constructor will throw a RuntimeError in case the projection
    cannot be initialized.
    

    C++ signature :
        void __init__(_object* [,std::string])

Overrides: object.__init__

Projects the given object (Envelope or Coord) 
from the geographic space into the cartesian space.

  Envelope.forward(self, projection),
  Coord.forward(self, projection).

Projects the given object (Envelope or Coord) 
from the cartesian space into the geographic space.

See also:
  Envelope.inverse(self, projection),
  Coord.inverse(self, projection).

params( (Projection)arg1) -> str :
    Returns the PROJ.4 string for this projection.
    

    C++ signature :
        std::string params(mapnik::projection {lvalue})

geographic

This property is True if the projection is a geographic projection (i.e. it uses lon/lat coordinates)
