Hi, yesterday I heard about Google's zopfli compression library which produces zlib (gzip) compatible output. Meaning you can compress with zopfli and decompress with zlib. I saw a chance here to create smaller HDF5 files without requiring a special filter on the reader's side.
Now my question is: How can I use my own filter to compress blocks and let other HDF5 applications think that they were compressed by H5Z_FILTER_DEFLATE? Currently I have a filter that uses zopfli for compression and zlib for decompression. In fact the decompression stage was copied from the standard GZIP filter. My implementation of the filter can be found here: https://github.com/felixr/hdf5-zopfli Best regards, Felix -- View this message in context: http://hdf-forum.184993.n3.nabble.com/Allow-std-gzip-filter-to-decompress-data-of-gzip-compatible-zopfli-filter-tp4025950.html Sent from the hdf-forum mailing list archive at Nabble.com. _______________________________________________ Hdf-forum is for HDF software users discussion.
