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
