# PHP Font Lib
This library can be used to:
* Read TrueType, OpenType (with TrueType glyphs), WOFF font files
* Extract basic info (name, style, etc)
* Extract advanced info (horizontal metrics, glyph names, glyph shapes, etc)
* Make an Adobe Font Metrics (AFM) file from a font
This project was initiated by the need to read font files in the [DOMPDF project](https://github.com/dompdf/dompdf).
Usage Example
-------------
### Base font information
```php
$font = \FontLib\Font::load('fontfile.ttf');
$font->parse(); // for getFontWeight() to work this call must be done first!
echo $font->getFontName() .'<br>';
echo $font->getFontSubfamily() .'<br>';
echo $font->getFontSubfamilyID() .'<br>';
echo $font->getFontFullName() .'<br>';
echo $font->getFontVersion() .'<br>';
echo $font->getFontWeight() .'<br>';
echo $font->getFontPostscriptName() .'<br>';
$font->close();
```
### Font Metrics Generation
```php
$font = FontLib\Font::load('fontfile.ttf');
$font->parse();
$font->saveAdobeFontMetrics('fontfile.ufm');
```
### Create a font subset
```php
$font = FontLib\Font::load('fontfile.ttf');
$font->parse();
$font->setSubset("abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ.:,;' (!?)+-*/== 1234567890"); // characters to include
$font->reduce();
touch('fontfile.subset.ttf');
$font->open('fontfile.subset.ttf', FontLib\BinaryStream::modeReadWrite);
$font->encode(array("OS/2"));
$font->close();
```
