Dear Graeme,

   I have made a new example that uses setters and writes a byte-offset
compressed image.  Testing revealed some bugs in the wrapper for
some of the setters, so I have also updated the release kit.  The whole
thing is  available on the  CBFlib_bleeding_edge svn on sourceforge as
well  as as a release kit

   http://downloads.sf.net/cbflib/CBFlib-0.9.2.6.tar.gz

Please give it a try and take a look at pycbf/pycbf_test4.py for an
example of writing a byte-offset CBF.  Let me know if it does what
you need.  If not, tell me what is missing or wrong and I'll be happy
to fix things and add more pycbf examples to the kit.

   Regards,
     Herbert

P.S.  This was a very useful question because it relate to testing the HDF5
changes.
