<!-- ==================== 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:
|
|
|
|
>>> 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 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.
