Mapnik Python module.
Boost Python bindings to the Mapnik C++ shared library.
Several things happen when you do:
2009-11-08 18:02:17 +01:00
2009-03-30 07:20:00 +02:00
> > > 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).
2009-11-08 18:02:17 +01:00
2009-03-30 07:20:00 +02:00
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.
2009-07-09 00:33:16 +02:00
3) All available input plugins and TrueType fonts are automatically registered.
2009-03-30 07:20:00 +02:00
2009-11-08 18:02:17 +01:00
4) Boost Python metaclass injectors are used in the '__init__.py' to extend several
2009-03-30 07:20:00 +02:00
objects adding extra convenience when accessed via Python.

Create a PostGIS Datasource.
Required keyword arguments:
dbname -- database name to connect to
table -- table name or subselect query
Optional db connection keyword arguments:
user -- database user to connect as (default: see postgres docs)
password -- password for database user (default: see postgres docs)
host -- portgres hostname (default: see postgres docs)
port -- postgres port (default: see postgres docs)
initial_size -- integer size of connection pool (default 1)
max_size -- integer max of connection pool (default 10)
Optional table-level keyword arguments:
extent -- manually specified data extent (comma delimited string, default None)
estimate_extent -- boolean, direct PostGIS to use the faster, less accurate estimate_extent() over extent() (default False)
row_limit -- integer limit of rows to return (default 0)
cursor_size -- integer size of cursor to fetch (default 0)
geometry_field -- specify geometry field (default first entry in geometry_columns)
multiple_geometries -- boolean, direct the Mapnik wkb reader to interpret as multigeometries (default False)
