HDF Image Format Conversion Utilities

This software is in the public domain. Please redistribute freely and keep
this README file and author notices with the rest of the software.

Contents ::

hdf2tiff - converts HDF images to TIFF images
tiff2hdf - converts TIFF images to HDF images
hdf2ras - converts HDF images to Sun Rasterfile images
ras2hdf - converts Sun Rasterfile images to HDF images

------------------------------------------------------------------------------
Formats:
Rasterfile - Sun specific file format for 8 and 24 bit images
HDF - NCSA 8 bit raster image format (used by ximage,
xdataslice, etc.)
- NCSA is the National Center for Supercomputing Applications
TIFF - General purpose tagged image format (Aldus and Microsoft)

------------------------------------------------------------------------------
Compatibility ::

These programs support HDF 8 bit raster images (i.e. those written using the
DFR8 series of routines.) They have been tested on ::
Sun 3 and Sun4 (OS4.0.3)
VAX Ultrix 3.1 (TIFF conversion only)

The HDF library version was 2.90.
The TIFF library version was 2.2.
Later versions and some earlier versions should work as well.

------------------------------------------------------------------------------
Building ::

With the given source code and Makefile, you'll need to install the HDF
include files in /usr/include/hdf, and the TIFF include files in
/usr/include/tiff.

The TIFF library is accessed as -ltiff and the HDF library is accessed as
-ldf. To compile the Rasterfile conversion code you must have the Sun pixrect
library available.

make - Makes all the converters
make - Makes the converter named

------------------------------------------------------------------------------
Enhancements ::

Here are a few enhancement you can make at home. [Mail the new versions to me
and I will integrate them into the standard version.]

- Support HDF 24 bit images
- Integrate the machine independent version of the pixrect library that PBM
uses
- Add a PPM or PGM converter (part of the PBM family)
- Manual pages

------------------------------------------------------------------------------
Availability ::

This software is available via anonymous FTP from think.com (131.239.2.1).
Transfer the file hdf_convert.shar.Z and use uncompress to restore the shar
script hdf_convert.shar. Typing /bin/sh hdf_convert.shar will restore the
files making up the conversion utilities.

HDF and TIFF availability ::

I've enclosed the portions of HDF and TIFF README files that state where to
get those libraries.


HDF Availability

This document describes how to obtain a version of HDF for your system. Other
information, including hints on using HDF, descriptions of the files that
comprise the distribution, and instructions on how to to create a library, can
be found in other README files in this directory.

There are two ways of obtaining HDF, depending on whether you are accessing
this system by remote login or anonymous ftp. Accordingly, this document
contains the following sections:

Obtaining HDF using anonymous ftp
Obtaining HDF using remote login

If you have any questions, problems or suggestions, you can contact us via
Email at [email protected] or [email protected], or by writing to Mike
Folk, Software Development, NCSA, 605 East Springfield Ave., Champaign, IL
61820, or call 217 244 0647.


************************************************************************
Obtaining HDF using anonymous ftp
************************************************************************

Login to zaphod.ncsa.uiuc.edu (128.174.20.50), with a login name of
"anonymous". Give your real name as password. Move to the directory "HDF" by
issuing the command "cd HDF" to ftp. Now you are ready to transfer files.
There are two ways to do this:

1. You may use the command "get hdf.tar" to download a "tar" format file. (Be
sure to set file transfer mode to binary with the command "binary".)
Unpacking hdf.tar with the Unix "tar" utility on your system will produce a
tree of subdirectories similar to the ones in this directory. These files
are described in README.SRC. They must be compiled according to the
instructions in that section. (NOTE: this tar file is very large, as it
contains source files for several systems, plus all of the documentation. If
space is dear, consider using the method described in the next paragraph.)

2. As an alternative to "tar", you may download the files you require
directly. Use "cd src" to move to the directory containing source files.
Then, move to the directory for your system. For instance, if you are on an
Alliant system, use "cd alliant". Then use the command "mget *". This will
prompt you for each of the source files, asking if you want to download them.
Answer "y" to each. This will produce the source files for that system in
your directory. Compile these files according to the instructions in the file
README.SRC.

To obtain the documentation enter "cd ../../doc" to move to the directory
containing the documentation. There are two subdirectories, with "ascii"
providing the documentation in readable form, and "word" providing it in
Macintosh Microsoft Word format. Each subdirectory has two subdirectories,
containing the user documentation (NCSA_HDF) and the technical specification
(HDF_Specs), respectively. The Word files must be downloaded in binary mode
with Macbinary mode enabled. The ascii files may be downloaded in ascii mode.

Mac users may download the file hdf.sit, which is HDF for the Mac in StuffIt
format. This is an archive containing all the files necessary to install HDF
on a Mac. This must be downloaded in binary mode, using the MacBinary option
on NCSA Telnet. Alternatively, the file hdf.sit.hqx may be downloaded in
ascii (normal) mode. This is a StuffIt file further encoded with BinHex.



**********************************************************************
Obtaining HDF using remote login
**********************************************************************

If you have an account on the NCSA Suns, you may download HDF in this way. To
obtain a copy of HDF for a particular system, login to zaphod.ncsa.uiuc.edu,
cd to the directory /sdg/ftp/HDF and use the "transfer" script.

Usage: transfer systemtype hostname [directory]

where systemtype is "unicos", "sun", "alliant", "iris4", "mac", "vms" or "pc",
hostname is the ftp name of the host you want to transfer the files to, and
directory is the directory on the target system in which you want the files to
be placed.

Transfer will create the source files appropriate for the system type, then
open an ftp connection to the target machine and ask you to login. When you
do, it will automatically copy the required files to the target system in the
directory you specified. It will also deposit all the documentation, in
Macintosh Microsoft Word format if transferring to a Macintosh, in ascii
format otherwise. It will deposit all the files in the same directory, as
contrasted to using the "tar" approach outlined in the section on anonymous
ftp, which will create a tree of subdirectories.

TIFF Availability

Tue Apr 17 17:57:27 PDT 1990

How To Obtain This Software (in case all you get is this file)

The software is available for public ftp on
ucbvax.berkeley.edu pub/tiff/tiff.tar.Z
(128.132.130.12)
uunet.uu.net graphics/tiff.tar.Z
(192.48.96.2)

For example,
ftp -n ucbvax.berkeley.edu
....
user anonymous
...
cd pub/tiff
binary
get tiff.tar.Z

The software comes in a compressed tar file. To extract the
information:
uncompress tiff.tar.Z (creates new file tiff.tar)
tar xf tiff.tar (extract individual files in current directory)

There is also companion compression tar file, tiffpics.tar.Z that has sample
TIFF image files. These are mostly useful in testing the software if/when you
port it to an unsupported system.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
