| 13 | libjpeg-turbo Licenses
|
|---|
| 14 | ======================
|
|---|
| 15 |
|
|---|
| 16 | libjpeg-turbo is covered by three compatible BSD-style open source licenses:
|
|---|
| 17 |
|
|---|
| 18 | - The IJG (Independent JPEG Group) License, which is listed in
|
|---|
| 19 | [README.ijg](README.ijg)
|
|---|
| 20 |
|
|---|
| 21 | This license applies to the libjpeg API library and associated programs
|
|---|
| 22 | (any code inherited from libjpeg, and any modifications to that code.)
|
|---|
| 23 |
|
|---|
| 24 | - The Modified (3-clause) BSD License, which is listed below
|
|---|
| 25 |
|
|---|
| 26 | This license covers the TurboJPEG API library and associated programs, as
|
|---|
| 27 | well as the build system.
|
|---|
| 28 |
|
|---|
| 29 | - The [zlib License](https://opensource.org/licenses/Zlib)
|
|---|
| 30 |
|
|---|
| 31 | This license is a subset of the other two, and it covers the libjpeg-turbo
|
|---|
| 32 | SIMD extensions.
|
|---|
| 33 |
|
|---|
| 34 |
|
|---|
| 35 | Complying with the libjpeg-turbo Licenses
|
|---|
| 36 | =========================================
|
|---|
| 37 |
|
|---|
| 38 | This section provides a roll-up of the libjpeg-turbo licensing terms, to the
|
|---|
| 39 | best of our understanding.
|
|---|
| 40 |
|
|---|
| 41 | 1. If you are distributing a modified version of the libjpeg-turbo source,
|
|---|
| 42 | then:
|
|---|
| 43 |
|
|---|
| 44 | 1. You cannot alter or remove any existing copyright or license notices
|
|---|
| 45 | from the source.
|
|---|
| 46 |
|
|---|
| 47 | **Origin**
|
|---|
| 48 | - Clause 1 of the IJG License
|
|---|
| 49 | - Clause 1 of the Modified BSD License
|
|---|
| 50 | - Clauses 1 and 3 of the zlib License
|
|---|
| 51 |
|
|---|
| 52 | 2. You must add your own copyright notice to the header of each source
|
|---|
| 53 | file you modified, so others can tell that you modified that file (if
|
|---|
| 54 | there is not an existing copyright header in that file, then you can
|
|---|
| 55 | simply add a notice stating that you modified the file.)
|
|---|
| 56 |
|
|---|
| 57 | **Origin**
|
|---|
| 58 | - Clause 1 of the IJG License
|
|---|
| 59 | - Clause 2 of the zlib License
|
|---|
| 60 |
|
|---|
| 61 | 3. You must include the IJG README file, and you must not alter any of the
|
|---|
| 62 | copyright or license text in that file.
|
|---|
| 63 |
|
|---|
| 64 | **Origin**
|
|---|
| 65 | - Clause 1 of the IJG License
|
|---|
| 66 |
|
|---|
| 67 | 2. If you are distributing only libjpeg-turbo binaries without the source, or
|
|---|
| 68 | if you are distributing an application that statically links with
|
|---|
| 69 | libjpeg-turbo, then:
|
|---|
| 70 |
|
|---|
| 71 | 1. Your product documentation must include a message stating:
|
|---|
| 72 |
|
|---|
| 73 | This software is based in part on the work of the Independent JPEG
|
|---|
| 74 | Group.
|
|---|
| 75 |
|
|---|
| 76 | **Origin**
|
|---|
| 77 | - Clause 2 of the IJG license
|
|---|
| 78 |
|
|---|
| 79 | 2. If your binary distribution includes or uses the TurboJPEG API, then
|
|---|
| 80 | your product documentation must include the text of the Modified BSD
|
|---|
| 81 | License (see below.)
|
|---|
| 82 |
|
|---|
| 83 | **Origin**
|
|---|
| 84 | - Clause 2 of the Modified BSD License
|
|---|
| 85 |
|
|---|
| 86 | 3. You cannot use the name of the IJG or The libjpeg-turbo Project or the
|
|---|
| 87 | contributors thereof in advertising, publicity, etc.
|
|---|
| 88 |
|
|---|
| 89 | **Origin**
|
|---|
| 90 | - IJG License
|
|---|
| 91 | - Clause 3 of the Modified BSD License
|
|---|
| 92 |
|
|---|
| 93 | 4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
|
|---|
| 94 | free of defects, nor do we accept any liability for undesirable
|
|---|
| 95 | consequences resulting from your use of the software.
|
|---|
| 96 |
|
|---|
| 97 | **Origin**
|
|---|
| 98 | - IJG License
|
|---|
| 99 | - Modified BSD License
|
|---|
| 100 | - zlib License
|
|---|
| 101 |
|
|---|
| 102 |
|
|---|
| 103 | The Modified (3-clause) BSD License

|
|---|
| 134 | Why Three Licenses?
|
|---|
| 135 | ===================
|
|---|
| 136 |
|
|---|
| 137 | The zlib License could have been used instead of the Modified (3-clause) BSD
|
|---|
| 138 | License, and since the IJG License effectively subsumes the distribution
|
|---|
| 139 | conditions of the zlib License, this would have effectively placed
|
|---|
| 140 | libjpeg-turbo binary distributions under the IJG License. However, the IJG
|
|---|
| 141 | License specifically refers to the Independent JPEG Group and does not extend
|
|---|
| 142 | attribution and endorsement protections to other entities. Thus, it was
|
|---|
| 143 | desirable to choose a license that granted us the same protections for new code
|
|---|
| 144 | that were granted to the IJG for code derived from their software.
