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
