README
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
$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
$font = FontLib\Font::load('fontfile.ttf'); $font->parse(); $font->saveAdobeFontMetrics('fontfile.ufm');
Create a font subset
$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();
