FREETYPE LICENSES
-----------------
The FreeType 2 font engine is copyrighted work and cannot be used
legally without a software license. In order to make this project
usable to a vast majority of developers, we distribute it under two
mutually exclusive open-source licenses.
This means that *you* must choose *one* of the two licenses described
below, then obey all its terms and conditions when using FreeType 2 in
any of your projects or products.
- The FreeType License, found in the file `docs/FTL.TXT`, which is
similar to the original BSD license *with* an advertising clause
that forces you to explicitly cite the FreeType project in your
product's documentation. All details are in the license file.
This license is suited to products which don't use the GNU General
Public License.
Note that this license is compatible to the GNU General Public
License version 3, but not version 2.
- The GNU General Public License version 2, found in
`docs/GPLv2.TXT` (any later version can be used also), for
programs which already use the GPL. Note that the FTL is
incompatible with GPLv2 due to its advertisement clause.
The contributed BDF and PCF drivers come with a license similar to
that of the X Window System. It is compatible to the above two
licenses (see files `src/bdf/README` and `src/pcf/README`). The same
holds for the source code files `src/base/fthash.c` and
2023-01-05 13:36:00 +01:00
`include/freetype/internal/fthash.h`; they were part of the BDF driver
in earlier FreeType versions.
The gzip module uses the zlib license (see `src/gzip/zlib.h`) which
too is compatible to the above two licenses.
The files `src/autofit/ft-hb.c` and `src/autofit/ft-hb.h` contain code
taken almost verbatim from the HarfBuzz file `hb-ft.cc`, which uses
the 'Old MIT' license, compatible to the above two licenses.
The MD5 checksum support (only used for debugging in development
builds) is in the public domain.
