Python bindings for Shapelib |
| 3 |
============================ |
| 4 |
|
| 5 |
These are three python modules for shapelib: |
| 6 |
|
| 7 |
shapelib read/write shapefiles |
| 8 |
|
| 9 |
dbflib read/write dbf files |
| 10 |
|
| 11 |
shptree quadtree for shapes |
| 12 |
|
| 13 |
Shapelib is a free software library for reading and writing ESRI shape |
| 14 |
files and can be found at http://shapelib.maptools.org/. |
| 15 |
|
| 16 |
The bindings were partly created with SWIG, a tool that can generate |
| 17 |
wrappers of C and C++ libraries for a variety of scripting languages. |
| 18 |
It's homepage is http://www.swig.org. |
| 19 |
|
| 20 |
The bindings themselves don't have a homepage at the moment, but the |
| 21 |
source tarballs/zip files can be downloaded from |
| 22 |
http://ftp.intevation.de/users/bh/pyshapelib/ |

Requirements |
| 26 |
------------ |
| 27 |
|
| 28 |
To compile the bindings, you need shapelib 1.2.9 or newer and Python 2.0 |
| 29 |
or newer. |
| 30 |
|
| 31 |
SWIG is not required. The files generated by SWIG are contained in the |
| 32 |
archive. If you modify shapelib.i or dbflib.i and need to recreate the |
| 33 |
generated files, you need SWIG 1.3 Alpha 5. It's unlikely that other |
| 34 |
versions will work. |
| 35 |
|
| 36 |
You also need Python, of course. If you installed prebuilt packages |
| 37 |
such as RPMs of some Linux distributions, please make sure that the |
| 38 |
development package is also installed. |

License |
| 42 |
------- |
| 43 |
|
| 44 |
The shapelib python bindings are covered by the LGPL. See COPYING for |
| 45 |
more information. |
| 46 |
|

|
| 48 |
Compilation and Installation |
| 49 |
---------------------------- |
| 50 |
|
| 51 |
Pyshapelib uses the python distutils which come with Python 2.0 or newer |
| 52 |
and are also available separately from python.org for older versions. |
| 53 |
|
| 54 |
To compile the bindings, unpack the archive under the shapelib archive |
| 55 |
or move the directory there if you've already unpacked it. The setup |
| 56 |
script expects to find the shapelib files in the parent directory. Then |
| 57 |
run |
| 58 |
|
| 59 |
python setup.py build |
| 60 |
|
| 61 |
to build the bindings. The result can be found under the (new) build |
| 62 |
subirectory. |
| 63 |
|
| 64 |
To install run |
| 65 |
|
| 66 |
python setup.py install |
| 67 |
|
| 68 |
which will install the bindings into python's site-packages directory. |
| 69 |
You can use the intall command's --prefix option to select a different |
| 70 |
installatin directory. |
| 71 |
|
| 72 |
For more information about the setup.py script, invoke it with the |
| 73 |
--help option: |
| 74 |
|
| 75 |
python setup.py --help |
| 76 |
|
| 77 |
|
| 78 |
Documentation |
| 79 |
------------- |
| 80 |
|
| 81 |
There's no real documentation for the python bindings themselves, but |
| 82 |
there's a simple demo/test script called pytest.py. |
| 83 |
|
| 84 |
The change history is recorded in NEWS and in detail in ChangeLog. |

pyshapelib is currently being developed as part of the interactive |
