=head1 NAME

PDF::API2::Basic::TTF::Prep - Preparation hinting program. Called when ppem changes

=head1 DESCRIPTION

This is a minimal class adding nothing beyond a table, but is a repository
for prep type information for those processes brave enough to address hinting.

=cut

use strict;
use vars qw(@ISA $VERSION);
use PDF::API2::Basic::TTF::Utils;

@ISA = qw(PDF::API2::Basic::TTF::Table);

$VERSION = 0.0001;


=head2 $t->read

Reads the data using C<read_dat>.

=cut

sub read
{
    $_[0]->read_dat;
    $_[0]->{' read'} = 1;
}


=head2 $t->out_xml($context, $depth)

Outputs Prep program as XML

=cut

sub out_xml
{
    my ($self, $context, $depth) = @_;
    my ($fh) = $context->{'fh'};
    my ($dat);

    $self->read;
    $dat = PDF::API2::Basic::TTF::Utils::XML_binhint($self->{' dat'});
    $dat =~ s/\n(?!$)/\n$depth$context->{'indent'}/omg;
    $fh->print("$depth<code>\n");
    $fh->print("$depth$context->{'indent'}$dat");
    $fh->print("$depth</code>\n");
    $self;
}


=head2 $t->XML_end($context, $tag, %attrs)

Parse all that hinting code
