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
