* The GIMP application core, and other portions of the official GIMP
|
|
distribution not explicitly licensed otherwise, are licensed under
|
|
the GNU GENERAL PUBLIC LICENSE -- see the 'COPYING' file in this
|
|
directory for details.
|
|
|
|
[ The below explicit exemption, we hope, clears up the GIMP
|
|
developers' position concerning an ambiguity with the GNU General
|
|
Public License concerning what constitutes a 'mere aggregation'
|
|
versus a combined or derived work. The intention is to make it
|
|
clear that arbitrarily-licensed programs such as GIMP plug-ins do
|
|
not automatically assume the GNU General Public License (GPL)
|
|
themselves simply because of their invocation of (or by) procedures
|
|
implemented in GPL-licensed code, via libgimp or a similar interface
|
|
to methods provided by the pdb: ]
|
|
|
|
* If you create a program which invokes (or provides) methods within
|
|
(or for) the GPL GIMP application core through the medium of libgimp
|
|
or another implementation of the 'procedural database' (pdb) serial
|
|
protocol, then the GIMP developers' position is that this is a 'mere
|
|
aggregation' of the program invoking the method and the program
|
|
implementing the method as per section 2 of the GNU General Public
|
|
License.
|
|
|
|
* 'libgimp' and the other GIMP libraries are licensed under the
|
|
GNU LESSER GENERAL PUBLIC LICENSE -- see the 'COPYING' file in the
|
|
libgimp directory for details.
|
|
|
|
* Icon themes are licensed under Creative Commons by-sa 3.0 or 4.0. See
|
|
the 'COPYING' files in icons/Symbolic and icons/Color respectively.
|
|
|
|
* Any data used in artworks, such as brushes, patterns and the like, and more
|
|
broadly likely all data inside the data/ folder should be under a CC0 license
|
|
(Creative Commons Zero) or equivalent, i.e. "No rights Reserved", because GIMP
|
|
contributors clearly don't intend to claim any right on anyone's work just
|
|
because they used GIMP and its default data.
|
|
We cannot clearly give proper licensing on all existing data, prior to the
|
|
addition of this note in the LICENSE file (for historical reasons, simply
|
|
because their contributors are since long gone), though we can say that an
|
|
uncountable number of users have used these for dozens of years and never had
|
|
legal problems as far as we know (it is anyway unclear whether anyone could
|
|
really claim any right for very basic brush or pattern usage). Since 2015, we
|
|
even have a clear FAQ entry to explicitly say the GIMP project has no
|
|
intention whatsoever to put restrictions on people's work:
|
|
https://www.gimp.org/docs/userfaq.html#can-i-use-gimp-commercially
|
|
|
|
Therefore any new data file under the data/ folder will be expected to be CC0.
|
|
All contributors are expected to read the LICENSE file and therefore are
|
|
implicitly agreeing to license their data under CC0 by contributing it as core
|
|
GIMP data.
