Python bindings for Shapelib |
| 3 |
|
|
============================ |
| 4 |
|
|
|
| 5 |
|
|
These are two python modules for shapelib created with SWIG. |
| 6 |
|
|
|
| 7 |
|
|
Shapelib is a free software library for reading and writing ESRI shape |
| 8 |
|
|
files and can be found at http://gdal.velocet.ca/projects/shapelib. |
| 9 |
|
|
|
| 10 |
|
|
SWIG is tool that can generate wrappers of C and C++ libraries for a |
| 11 |
|
|
variety of scripting languages. It's homepage is www.swig.org. |
| 12 |
|
|
|
| 13 |
|
|
The two modules here wrap the shape file reading and writing API and the |
| 14 |
|
|
DBF file reading and writing API. The shape file bindings are currently |
| 15 |
|
|
limited to 2-dimensional data. |

Requirements |
| 19 |
|
|
------------ |
| 20 |
|
|
|
| 21 |
|
|
To compile the bindings, you need shapelib 1.2.8. Older versions may or |
| 22 |
|
|
may not work, I've only tested the code with 1.2.8. |
| 23 |
|
|
|
| 24 |
|
|
SWIG is not required. The files generated by SWIG are contained in the |
| 25 |
|
|
archive. If modify shapelib.i or dbflib.i and need to recreate the |
| 26 |
|
|
generated files, you need at least SWIG 1.3. |
| 27 |
|
|
|
| 28 |
|
|
You also need Python, of course. If you installed prebuilt packages such |
| 29 |
|
|
as RPMs of some Linux distributions, please make sure that the |
| 30 |
|
|
development package is also installed. |

Compilation and Installation |
| 41 |
|
|
---------------------------- |
| 42 |
|
|
|
| 43 |
|
|
Pyshapelib uses the python distutils which come with Python 2.0 or newer |
| 44 |
|
|
and are also available separately from python.org for older versions. |
| 45 |
|
|
|
| 46 |
|
|
To compile the bindings, unpack the archive under the shapelib archive |
| 47 |
|
|
or move the directory there if you've already unpacked it. Then run |
| 48 |
|
|
|
| 49 |
|
|
python setup.py build |
| 50 |
|
|
|
| 51 |
|
|
to build the bindings. The result can be found under the (new) build |
| 52 |
|
|
subirectory. |
| 53 |
|
|
|
| 54 |
|
|
To install run |
| 55 |
|
|
|
| 56 |
|
|
python setup.py install |
| 57 |
|
|
|
| 58 |
|
|
which will install the bindings into python's site-packages directory. |
| 59 |
|
|
You can use the intall command's --prefix option to select a different |
| 60 |
|
|
installatin directory. |
| 61 |
|
|
|
| 62 |
|
|
For more information about the setup.py script, invoke it with the |
| 63 |
|
|
--help option: |
| 64 |
|
|
|
| 65 |
|
|
python setup.py --help |

Documentation |
| 69 |
|
|
------------- |
| 70 |
|
|
|
| 71 |
|
|
There's no real documentation for the python bindings themselves, but |
| 72 |
|
|
there's a simple demo/test script called pytest.py. |
