php font lib

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();
