NAME

       hdfcomp - compress 8-bit raster images in an HDF file

SYNOPSIS

       hdfcomp output-filename [-c|-r|-i] input-filename-1 [-c|-r|-i] input-filename-2...

DESCRIPTION

       hdfcomp  reads  RIS8  images  from  a  set  of  HDF  files, compresses them and stores the
       compressed data in a second HDF file.  If the  output  HDF  file  exists,  the  compressed
       images will be appended to it.

OPTIONS

       -r     No Compression.  Apply no compression to the output data. (the default).

       -c     Run length coding.  Compress the output data using run-length encoding.

       -i     IMCOMP Compression.  Compress the output data using the IMCOMP method.

EXAMPLES

       A  directory  contains twenty files named "storm001", "storm002", ...  "storm020". Each of
       these files contains a single RIS8  image.  To  compress  these  images  using  run-length
       encoding and store them in a file named "altcomp.hdf", use the following hdfcomp command:

               hdfcomp allcomp.hdf -c storm*.hdf
