| 55 |
|
|---|
| 56 | This library may include third party font files released with different licenses.
|
|---|
| 57 |
|
|---|
| 58 | All the PHP files on the fonts directory are subject to the general TCPDF license (GNU-LGPLv3),
|
|---|
| 59 | they do not contain any binary data but just a description of the general properties of a particular font.
|
|---|
| 60 | These files can be also generated on the fly using the font utilities and TCPDF methods.
|
|---|
| 61 |
|
|---|
| 62 | All the original binary TTF font files have been renamed for compatibility with TCPDF and compressed using the gzcompress PHP function that uses the ZLIB data format (.z files).
|
|---|
| 63 |
|
|---|
| 64 | The binary files (.z) that begins with the prefix "free" have been extracted from the GNU FreeFont collection (GNU-GPLv3).
|
|---|
| 65 | The binary files (.z) that begins with the prefix "pdfa" have been derived from the GNU FreeFont, so they are subject to the same license.
|
