<!-- ==================== PACKAGE DESCRIPTION ==================== -->
<h1 class="epydoc">Package mapnik</h1><p class="nomargin-top"></p>
<pre class="literalblock">
Mapnik Python module.
Boost Python bindings to the Mapnik C++ shared library.
Several things happen when you do:
&gt;&gt;&gt; import mapnik
1) Mapnik C++ objects are imported via the '__init__.py' from the '_mapnik.so' shared object
which references libmapnik.so (linux), libmapnik.dylib (mac), or libmapnik.dll (win).
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 wrap/extend several
objects adding extra convenience when accessed via Python.
Note: besides those objects modified by boost metaclass injection all class objects
are only accessible by various documentation viewers via the 'mapnik._mapnik' module.
