[gdal-dev] gdal and python 2.5

[Michael ODonnell]

Thank you Howard! No this does not help my immediate situation, but it sounds like it is not far off, and I don't have the skills to do what the programming group is doing so I can't complain.

Has anyone used PIL (python imaging library)? I am guessing this does not give me nearly as much of the functionality that comes with gdal/osr, especially how to embed the spatial reference tags, but I recently stumbled across this.

http://trac.osgeo.org/gdal/wiki/GdalOgrInPython#the-history-of-using-gdal-ogr-in-python 
   describes the current situation.  For GDAL 1.5, the Python bindings
  
will be numpy only, and Numeric support is not provided.  Your code  
may require some minor tweaks to be able to use numpy, but none of the
  
scripts I have ported for use in the GDAL project required significant
  
changes.

"Stock" Python 2.5 from python.org and ActiveState use 2003.  If we  
are to provide pre-built bindings, they must use msvc2003.

It is my intention that we (the GDAL project) will provide Python  
bindings (2.3, 2.4, and 2.5) in the form of eggs and windows  
installers on http://pypi.python.org/pypi/GDAL/ that will be expected  
to be used with our "official" binaries that we will make available on
 http://download.osgeo.org/gdal/win32/ 
  for the GDAL 1.5 release.  We haven't gotten our story straight on  
what the official binaries will look like quite yet, however.  I know  
this story doesn't quite help your immediate problem.

If we make a 1.5 beta binary in a few days, I will upload a  
corresponding egg/.exe to pypi to match them.  If it doesn't happen  
right away, please note that the 1.5 will be happening by the end of  
the month, so we should at least have something by then.

As a side note, I expect the official GDAL binaries will be compiled  
with msvc2005, but it shouldn't be a problem to have the Python  
bindings that were built with 2003 link against them now that the  
Python bindings in 1.5 no longer use and C++ API.

Hope this helps,

Howard
