13 Permission is hereby granted to use, copy, modify, and distribute this | |
14 software (or portions thereof) for any purpose, without fee, subject to these | |
15 conditions: | |
16 (1) If any part of the source code for this software is distributed, then this | |
17 README file must be included, with this copyright and no-warranty notice | |
18 unaltered; and any additions, deletions, or changes to the original files | |
19 must be clearly indicated in accompanying documentation. | |
20 (2) If only executable code is distributed, then the accompanying | |
21 documentation must state that "this software is based in part on the work of | |
22 the Independent JPEG Group". | |
23 (3) Permission for use of this software is granted only if the user accepts | |
24 full responsibility for any undesirable consequences; the authors accept | |
25 NO LIABILITY for damages of any kind. | |
26 | |
27 These conditions apply to any software derived from or based on the IJG code, | |
28 not just to the unmodified library. If you use our work, you ought to | |
29 acknowledge us. | |

31 Permission is NOT granted for the use of any IJG author's name or company name | |
32 in advertising or publicity relating to this software or products derived from | |
33 it. This software may be referred to only as "the Independent JPEG Group's | |
34 software". | |
35 | |
36 We specifically permit and encourage the use of this software as the basis of | |
37 commercial products, provided that all warranty or liability claims are | |
38 assumed by the product vendor. | |

41 ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, | |
42 sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA. | |
43 ansi2knr.c is NOT covered by the above copyright and conditions, but instead | |
44 by the usual distribution terms of the Free Software Foundation; principally, | |
45 that you must include source code if you redistribute it. (See the file | |
46 ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part | |
47 of any program generated from the IJG code, this does not limit you more than | |
48 the foregoing paragraphs do. | |

50 The Unix configuration script "configure" was produced with GNU Autoconf. | |
51 It is copyright by the Free Software Foundation but is freely distributable. | |
52 The same holds for its supporting scripts (config.guess, config.sub, | |
53 ltconfig, ltmain.sh). Another support script, install-sh, is copyright | |
54 by M.I.T. but is also freely distributable. | |
55 | |
56 It appears that the arithmetic coding option of the JPEG spec is covered by | |
57 patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot | |
58 legally be used without obtaining one or more licenses. For this reason, | |
59 support for arithmetic coding has been removed from the free JPEG software. | |
60 (Since arithmetic coding provides only a marginal gain over the unpatented | |
61 Huffman mode, it is unlikely that very many implementations will support it.) | |
62 So far as we are aware, there are no patent restrictions on the remaining | |
63 code. | |
64 | |
65 The IJG distribution formerly included code to read and write GIF files. | |
66 To avoid entanglement with the Unisys LZW patent, GIF reading support has | |
67 been removed altogether, and the GIF writer has been simplified to produce | |
68 "uncompressed GIFs". This technique does not use the LZW algorithm; the | |
69 resulting GIF files are larger than usual, but are readable by all standard | |
70 GIF decoders. | |
71 | |
72 We are required to state that | |
73 "The Graphics Interchange Format(c) is the Copyright property of | |
74 CompuServe Incorporated. GIF(sm) is a Service Mark property of | |
