=head1 NAME

Font::TTF::Prop - Glyph Properties table in a font

=head1 DESCRIPTION

=head1 INSTANCE VARIABLES

=over

=item version

=item default

=item lookup

Hash of property values keyed by glyph number

=item lookupFormat

=back

=head1 METHODS

=cut

use vars qw(@ISA);

use Font::TTF::Segarr;

@ISA = qw(Font::TTF::Table);

=head2 $t->read

Reads the table into memory

=cut

=head2 $t->out($fh)

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

=cut

    AAT_write_lookup($fh, $self->{'format'}, $lookup, 2, $default) if (defined $lookup);
}

=head2 $t->minsize()

Returns the minimum size this table can be. If it is smaller than this, then the table
must be bad and should be deleted or whatever.

=cut

sub minsize

=head2 $t->print($fh)

Prints a human-readable representation of the table
