Xfig is a menu-driven tool that allows the user to draw and manipulate objects interactively in an X window. The resulting pictures can be saved, printed on postscript printers or converted to a variety of other formats.
This package also includes TransFig, a set of tools for creating TeX and LaTeX documents with graphics which are portable, in the sense that they can be printed in a wide variety of environments. Xfig automatically runs TransFig when necessary.
The original authors of Xfig are Supoj Sutanthavibul, Paul King, and Brian V. Smith. The original authors of TransFig include Supoj Sutanthavibul, Micah Beck, Frank Schmuck, Conrad Kwok, and Brian Smith. Xfig and TransFig are currently being maintained by Brian Smith, who claims the following:

Xfig uses the Independent JPEG Group's JPEG software library, which is the work of Tom Lane, Philip Gladstone, Luis Ortiz, Jim Boucher, Lee Crocker, George Phillips, Davide Rossi, Ge' Weijers, and other members of the Independent JPEG Group.
IJG is not associated with the official ISO JPEG standards committee.
The authors of the Independent JPEG Group's JPEG software library state the following:
In plain English:
- We don't promise that this software works. (But if you find any bugs, please let us know!)
- You can use this software for whatever you want. You don't have to pay us.
- You may not pretend that you wrote this software. If you use it in a program, you must acknowledge somewhere in your documentation that you've used the IJG code.
In legalese:
The authors make NO WARRANTY or representation, either express or implied, with respect to this software, its quality, accuracy, merchantability, or fitness for a particular purpose. This software is provided "AS IS", and you, its user, assume the entire risk as to its quality and accuracy.
This software is copyright (C) 1991, 1992, 1993, 1994, 1995, Thomas G. Lane. All Rights Reserved except as specified below.
Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for any purpose, without fee, subject to these conditions:
- If any part of the source code for this software is distributed, then this README file must be included, with this copyright and no-warranty notice unaltered; and any additions, deletions, or changes to the original files must be clearly indicated in accompanying documentation.
- If only executable code is distributed, then the accompanying documentation must state that "this software is based in part on the work of the Independent JPEG Group".
- Permission for use of this software is granted only if the user accepts full responsibility for any undesirable consequences; the authors accept NO LIABILITY for damages of any kind.
These conditions apply to any software derived from or based on the IJG code, not just to the unmodified library. If you use our work, you ought to acknowledge us.
Permission is NOT granted for the use of any IJG author's name or company name in advertising or publicity relating to this software or products derived from it. This software may be referred to only as "the Independent JPEG Group's software".
We specifically permit and encourage the use of this software as the basis of commercial products, provided that all warranty or liability claims are assumed by the product vendor.
ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.ansi2knr.c is NOT covered by the above copyright and conditions, but instead by the usual distribution terms of the Free Software Foundation; principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part of any program generated from the IJG code, this does not limit you more than the foregoing paragraphs do.
The configuration script "configure" was produced with GNU Autoconf. It is copyright by the Free Software Foundation but is freely distributable.
It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more licenses. For this reason, support for arithmetic coding has been removed from the free JPEG software. (Since arithmetic coding provides only a marginal gain over the unpatented Huffman mode, it is unlikely that very many implementations will support it.) So far as we are aware, there are no patent restrictions on the remaining code.
WARNING: Unisys has begun to enforce their patent on LZW compression against GIF encoders and decoders. You will need a license from Unisys to use the included rdgif.c or wrgif.c files in a commercial or shareware application. At this time, Unisys is not enforcing their patent against freeware, so distribution of this package remains legal. However, we intend to remove GIF support from the IJG package as soon as a suitable replacement format becomes reasonably popular.
We are required to state that

All of the subsystems for this product can be installed using IRIX. You do not need to use the miniroot. Refer to the Software Installation Administrator's Guide for complete installation instructions.
This software is compatible with IRIX 5.3 and IRIX 6.1.
The Xfig manual documents the Xfig system. The manual is also provided in on-line text format; type "man xfig" to read it.
While TransFig is normally transparent to users of Xfig, it can be useful in its own right. For information on TransFig, read the Transfig Manual. Commands included with TransFig each have man pages, readable online by typing "man COMMAND_NAME_HERE". These commands include transfig, fig2dev, fig2ps2tex, and pic2tpic.
