About

A library to read, parse, export and make subsets of different types of font files.

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.

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();
