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

- 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
