Welcome to H5Z-ZFP

H5Z-ZFP is a compression filter for HDF5 using the ZFP compression library, supporting lossy and lossless compression of floating point and integer data to meet bitrate, accuracy, and/or precision targets. The filter uses the registered HDF5 filter ID, 32013. It supports single and double precision floating point and integer data chunked in 1, 2 or 3 dimensions. The filter will function on datasets of more than 3 dimensions (or 4 dimensions for ZFP versions 0.5.4 and newer), albeit at the possible expense of compression performance, as long as no more than 3 (or 4) dimensions of the HDF5 dataset chunking are of size greater than 1.
