gzip support in dream3d file format #790

Open Micket opened 6 years ago

Micket commented 6 years ago

We develop a tool that outputs synthetic microstructures directly as a *.dream3d data file, and after a bit of debugging, I realized that it was the HDF standard compression of datasets I started using a while back.

I see a drastic decrease in file size with a simple gzip (default compression) turned on (over 50 times smaller!), so it would be a shame if it could not be supported in DREAM3D.

We can look into supporting this in DREAM.3D. Historically HDF5 did not include all the libraries needed for portable compression. By that I mean that some systems had zlib included and some did not which created all sorts of problems when creating a redistributable package. It is probably time to take another look at enabling the compression in HDF5.
