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
|
||
|
|
`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.
