LZ4 compression with PyImarisWriter #8

Open rharkes opened 2 years ago

rharkes commented 2 years ago

Is this not yet supported? I see nothing in the unit test, and when trying to write a file with LZ4 compression I get no errors, but the result is uncompressed.

Did you use shuffle?

LZ4 is supported by ImarisWriter and PyImarisWriter, but it requires hdf5 to support it also. LZ4 can be added as a plugin (see https://portal.hdfgroup.org/display/support/HDF5+Filter+Plugins). Does this help?

Thanks! I tried with and without shuffle, but no LZ4. I'll try to add it to HDF5.
