[Lcms-user] ctypes Python bindings

[Guy K. K. <G....@ma...>]

Hi,

I'm currently working on Python bindings for liblcms using ctypes as I've 
outlined sometimes in the past (June, July) already. Actually, it's quite 
easy. The main bindings are all generated using Thomas Heller's code 
generator for ctypes in ctypeslib.

So far I've got a generated wrapper working, that can already do all the stuff 
the official bindings can do. Although this has not been tested extensively. 
But previously unavailable bindings e. g. for float values of colour values, 
etc. are now also easily possible.

Still need to do some things, but mainly to make things "nicer". The way it is 
currently structured:

 * _lcms.py (generated module with all bindings)
 * c_lcms.py (module to take some cleanups to make the bindings more Pythonic)
 * lcms.py (could also be called differently. But this is for an OO wrapped
   API that is to ease the use of LittleCMS under Python)

Things still to do:

 * split up the code generation into three sub-modules:
   * LCMS base (API basics as version, ...; constants; flags for colour space
     type, rendering intent, ...)
   * LCMS types
   * LCMS functions

Well, if anybody is interested. Give me a shout. The stuff is usable already, 
however the Python API and the module arrangement will still fluctuate a bit.

One of the questions I'm having now is this: Where to host the code? Should it 
go into the original LittleCMS CVS repository, or somewhere else?

Oh, and it works nicely together with numpy. I think Frédéric asked about 
that. So interaction with PIL images should be also quite easily done.
