hrepack - copies an HDF file to a new file

hrepack copies an HDF file to a new file with/without compression and/or chunking.

       compresses all objects in the file file1.hdf, using RLE compression

       hrepack-v-ifile1.hdf-ofile2.hdf-t '*:RLE'

       applies Skipping Huffman compression with skip factor of 1, for objects /group1/A, /group2/B and C

       hrepack-v-ifile1.hdf-ofile2.hdf-t '/group1/A,/group2/B,C:HUFF 1'

       applies RLE compression for object /group1/D.

       applies chunking to objects D and E using a chunk size of 10 for the 2 dimensions

       hrepack-v-ifile1.hdf-ofile2.hdf-t '/group1/D:RLE' -c 'D,E:10x10'

       uncompresses object A

       hrepack-v-ifile1.hdf-ofile2.hdf-t 'A:NONE'

       applies SZIP compression to object A, with parameters 8 and NN

       hrepack-v-ifile1.hdf-ofile2.hdf-t 'A:SZIP 8,NN'

       Note: the use of the verbose option -v is recommended

       hrepack - copies an HDF file to a new file

-iinput
              input HDF File

       -ooutput
              output HDF File

       -V     prints version of the HDF4 library and exits

       -h     prints usage information

       -v     verbose mode

       -tcomp_info
              compression  type: 'comp_info' is a string with the format <object list>:<type of compression><pa‐
              rameters>

              <object list> is a comma separated list of object names meaning apply compression  only  to  those
              objects.  '*' means all objects.

              <type of compression> can be:
              RLE

              for RLE compression

              HUFF

              for Huffman

              GZIP

              for gzip

              JPEG

              for JPEG (for images only)

              SZIP

              for szip

              NONE

              to uncompress

       <parameters> is optional compression info
              RLE

              no parameter

              HUFF

              the skip-size

              GZIP

              the deflation level

              JPEG

              the quality factor

              SZIP

              pixels per block, compression mode (NN or EC)

       -cchunk_info
              apply chunking.  chunk_info is a string with the format <object list>:<chunk information>

              <object  list>  is a comma separated list of object names meaning apply chunking only to those ob‐
              jects.  '*' means all objects

              <chunk information> is the chunk size of each dimension: dim_1xdim_2x...dim_n  or  NONE,  to
              unchunk a previous chunked object

       -fcfile
              file with compression information -t and -c-msize
              do not compress objects smaller than size (bytes)
