| Werner Lemberg | a16c4a7 | 2003-04-21 13:30:27 +0000 | [diff] [blame] | 2 | The FreeType 2 font engine is copyrighted work and cannot be used |
| 3 | legally without a software license. In order to make this project |
| 4 | usable to a vast majority of developers, we distribute it under two |
| Werner Lemberg | 82906bf | 2003-11-04 18:24:20 +0000 | [diff] [blame] | 5 | mutually exclusive open-source licenses. |

| Werner Lemberg | 82906bf | 2003-11-04 18:24:20 +0000 | [diff] [blame] | 7 | This means that *you* must choose *one* of the two licenses described |
| Werner Lemberg | a16c4a7 | 2003-04-21 13:30:27 +0000 | [diff] [blame] | 8 | below, then obey all its terms and conditions when using FreeType 2 in |
| 9 | any of your projects or products. |
| 10 | |
| Werner Lemberg | 82906bf | 2003-11-04 18:24:20 +0000 | [diff] [blame] | 11 | - The FreeType License, found in the file `FTL.TXT', which is similar |
| 12 | to the original BSD license *with* an advertising clause that forces |
| 13 | you to explicitly cite the FreeType project in your product's |
| 14 | documentation. All details are in the license file. This license |
| 15 | is suited to products which don't use the GNU General Public |
| 16 | License. |

| 19 | License version 3, but not version 2. |
| 20 | |
| 21 | - The GNU General Public License version 2, found in `GPLv2.TXT' (any |
| Werner Lemberg | 666e386 | 2003-11-06 14:56:11 +0000 | [diff] [blame] | 22 | later version can be used also), for programs which already use the |
| Werner Lemberg | ea79b84 | 2011-06-18 08:06:57 +0200 | [diff] [blame] | 23 | GPL. Note that the FTL is incompatible with GPLv2 due to its |
| Werner Lemberg | 666e386 | 2003-11-06 14:56:11 +0000 | [diff] [blame] | 24 | advertisement clause. |

| Werner Lemberg | c98a40f | 2015-12-19 16:59:40 +0100 | [diff] [blame] | 26 | The contributed BDF and PCF drivers come with a license similar to that |
| Werner Lemberg | 939bc78 | 2009-10-29 09:28:27 +0100 | [diff] [blame] | 27 | of the X Window System. It is compatible to the above two licenses (see |
| Werner Lemberg | c98a40f | 2015-12-19 16:59:40 +0100 | [diff] [blame] | 28 | file src/bdf/README and src/pcf/README). The same holds for the files |
| 29 | `fthash.c' and `fthash.h'; their code was part of the BDF driver in |
| 30 | earlier FreeType versions. |

| 32 | The gzip module uses the zlib license (see src/gzip/zlib.h) which too is |
| 33 | compatible to the above two licenses. |
