"""Mapnik Python module.
|
|
|
|
Boost Python bindings to the Mapnik C++ shared library.
|
|
|
|
Several things happen when you do:
|
|
|
|
>>> import mapnik
|
|
|
|
1) Mapnik C++ objects are imported via the '__init__.py' from the '_mapnik.so' shared object
|
|
(_mapnik.pyd on win) which references libmapnik.so (linux), libmapnik.dylib (mac), or
|
|
mapnik.dll (win32).
|
|
|
|
2) The paths to the input plugins and font directories are imported from the 'paths.py'
|
|
file which was constructed and installed during SCons installation.
|
|
|
|
3) All available input plugins and TrueType fonts are automatically registered.
|
|
|
|
4) Boost Python metaclass injectors are used in the '__init__.py' to extend several
|
|
objects adding extra convenience when accessed via Python.
