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
