Hi,
sorry if this is a stupid question (i looked on the website and googled but
couldn't find much):
is it possible to use compression tool other than szip for hdf5 files? If so
is there documentation on how this is accomplished?
thanks
matt

I guess I looked at the source code for the szip compressor H5Zszip.c
Ref. manual on H5Zregister() was useful too.

I don't think this is documented extensively, but you can always have a look
at existing wrappers. Here it is one example for Blosc:
http://blosc.pytables.org/trac/browser/trunk/hdf5/blosc_filter.c
and here for LZO and bzip2:
http://www.pytables.org/trac/browser/trunk/src/H5Zlzo.c
http://www.pytables.org/trac/browser/trunk/src/H5Zbzip2.c
all three are registered by THG, so you can use them as-is and don't be afraid
that their IDs would be overwritten by other filters in the future.
