libjpeg-turbo Licenses |
|
====================== |
|
|
|
libjpeg-turbo is covered by three compatible BSD-style open source licenses: |
|
|
|
- The IJG (Independent JPEG Group) License, which is listed in |
|
[README.ijg](README.ijg) |
|
|
|
This license applies to the libjpeg API library and associated programs |
|
(any code inherited from libjpeg, and any modifications to that code.) |
|
|
|
- The Modified (3-clause) BSD License, which is listed below |
|
|
|
This license covers the TurboJPEG API library and associated programs. |
|
|
|
- The zlib License, which is listed below |
|
|
|
This license is a subset of the other two, and it covers the libjpeg-turbo |
|
SIMD extensions. |
|
|
|
|
|
Complying with the libjpeg-turbo Licenses |
|
========================================= |
|
|
|
This section provides a roll-up of the libjpeg-turbo licensing terms, to the |
|
best of our understanding. |
|
|
|
1. If you are distributing a modified version of the libjpeg-turbo source, |
|
then: |
|
|
|
1. You cannot alter or remove any existing copyright or license notices |
|
from the source. |
|
|
|
**Origin** |
|
- Clause 1 of the IJG License |
|
- Clause 1 of the Modified BSD License |
|
- Clauses 1 and 3 of the zlib License |
|
|
|
2. You must add your own copyright notice to the header of each source |
|
file you modified, so others can tell that you modified that file (if |
|
there is not an existing copyright header in that file, then you can |
|
simply add a notice stating that you modified the file.) |
|
|
|
**Origin** |
|
- Clause 1 of the IJG License |
|
- Clause 2 of the zlib License |
|
|
|
3. You must include the IJG README file, and you must not alter any of the |
|
copyright or license text in that file. |
|
|
|
**Origin** |
|
- Clause 1 of the IJG License |
|
|
|
2. If you are distributing only libjpeg-turbo binaries without the source, or |
|
if you are distributing an application that statically links with |
|
libjpeg-turbo, then: |
|
|
|
1. Your product documentation must include a message stating: |
|
|
|
This software is based in part on the work of the Independent JPEG |
|
Group. |
|
|
|
**Origin** |
|
- Clause 2 of the IJG license |
|
|
|
2. If your binary distribution includes or uses the TurboJPEG API, then |
|
your product documentation must include the text of the Modified BSD |
|
License. |
|
|
|
**Origin** |
|
- Clause 2 of the Modified BSD License |
|
|
|
3. You cannot use the name of the IJG or The libjpeg-turbo Project or the |
|
contributors thereof in advertising, publicity, etc. |
|
|
|
**Origin** |
|
- IJG License |
|
- Clause 3 of the Modified BSD License |
|
|
|
4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be |
|
free of defects, nor do we accept any liability for undesirable |
|
consequences resulting from your use of the software. |
|
|
|
**Origin** |
|
- IJG License |
|
- Modified BSD License |
|
- zlib License |
|
|
|
