[Gdal-dev] Building a Projection Dialog

[Even Rouault]

Indeed, the OPT functions are exposed through swig.

Here's the comment from swig/include/osr.i :

/*
 * Python has it's own custom interface to GetProjectionMethods().which 
returns
 * fairly complex structure.
 *
 * All other languages will have a more simplistic interface which is
 * exactly the same as the C api.
 * 
 */

I've checked that the Python osr.GetProjectionMethods() works as expected, but 
I wouldn't be surprised if the other languages miss the necessary typemaps.
