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:
'SCRIPT' -- retrieve script tag or name
'LANGUAGE' -- retrieve language tag or name
'FEATURE' -- retrieve feature tag or name
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.
METHODS¶
readtagsfile ( filename )¶
Read a file in the syntax of Tags.txt (included with Microsoft VOLT) to obtain additional/replacement tag definitions.
Returns 0 if cannot open the file; else 1.
