NAME

       Font::TTF::OTTags - Utilities for TrueType/OpenType tags

SYNOPSIS

         use Font::TTF::OTTags qw( %tttags %ttnames %iso639 readtagsfile );

         # Look at built-in stuff:
         $script_tag = $tttags{'SCRIPT'}{'Cypriot Syllabary'};  # returns 'cprt'
         $lang_name = $ttnames{'LANGUAGE'}{'ALT '};             # returns 'Altai'

         # Map iso639 tag to/from OT lang tag
         @isotags = $iso639{'ALT '};    # returns [ 'atv', 'alt' ]
         $lang_tag = $iso639{'atv'};    # returns 'ALT '

         # Read latest tags file to add to built-in definitions
         readtagsfile ("C:\\Program Files\\Microsoft VOLT\\TAGS.txt");

       First-level keys to %tttags and %ttnames are:

       Built-in      data      has      been      derived      from      Microsofts      tag     registry     at
       <http://www.microsoft.com/typography/otspec/ttoreg.htm>, updated to draft v1.5 of the OpenType Spec.
