7

SYNOPSIS

9         use Font::TTF::OTTags qw( %tttags %ttnames %iso639 readtagsfile );
10
11         # Look at built-in stuff:
12         $script_tag = $tttags{'SCRIPT'}{'Cypriot Syllabary'};  # returns 'cprt'
13         $lang_name = $ttnames{'LANGUAGE'}{'ALT '};             # returns 'Altai'
14
15         # Map iso639-2 tag to/from OT lang tag
16         @isotags = $iso639{'ALT '};    # returns [ 'atv', 'alt' ]
17         $lang_tag = $iso639{'atv'};    # returns 'ALT '
18
19         # Read latest tags file to add to built-in definitions
20         readtagsfile ("C:\\Program Files\\Microsoft VOLT\\TAGS.txt");
21
22       First-level keys to %tttags and %ttnames are:
23
24       SCRIPT
25           retrieve script tag or name

33       Built-in data has been derived from the 2014-07-11 draft of the 3rd
34       edition of ISO/IEC 14496-22 (Information technology - Coding of audio-
35       visual objects - Part 22: Open Font Format) which, when finalized and
36       approved, will replace the second edition (ISO/IEC 14496-22:2009).
