[-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).

-
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
