    version
    FontNumber
    Pitch
    xHeight
    Style
    TypeFamily
    CapHeight
    SymbolSet
    Typeface
    CharacterComplement
    FileName
    StrokeWeight
    WidthType
    SerifStyle

Notice that C&lt;Typeface&gt;, C&lt;CharacterComplement&gt; and C&lt;FileName&gt; return arrays
of unsigned characters of the appropriate length

use strict;
use vars qw(@ISA %fields @field_info);

require Font::TTF::Table;
use Font::TTF::Utils;

@ISA = qw(Font::TTF::Table);
@field_info = (
    'version' =&gt; 'v',
    'FontNumber' =&gt; 'L',

sub init
{
    my ($k, $v, $c, $i);
    for ($i = 0; $i &lt; $#field_info; $i += 2)
    {
        ($k, $v, $c) = TTF_Init_Fields($field_info[$i], $c, $field_info[$i + 1]);
        next unless defined $k &amp;&amp; $k ne "";
        $fields{$k} = $v;
    }
}


=head2 $t-&gt;read

Reads the table into memory thanks to some utility functions

=cut

sub read
{
    my ($self) = @_;
    my ($dat);

    $self-&gt;SUPER::read || return $self;

    init unless defined $fields{'xHeight'};
    $self-&gt;{' INFILE'}-&gt;read($dat, 54);

    TTF_Read_Fields($self, $dat, \%fields);
    $self;
}


=head2 $t-&gt;out($fh)

Writes the table to a file either from memory or by copying.

=cut

sub out
{
    my ($self, $fh) = @_;

    return $self-&gt;SUPER::out($fh) unless $self-&gt;{' read'};
    $fh-&gt;print(TTF_Out_Fields($self, \%fields, 54));
}
