=head1 NAME

PDF::API2::Basic::PDF::Page - Low-level PDF page object

=head1 DESCRIPTION

Represents a page of output in PDF. It also keeps track of the content stream,
any resources (such as fonts) being switched, etc.

Page inherits from Pages due to a number of shared methods. They are really
structurally quite different.

=head1 INSTANCE VARIABLES

A page has various working variables:

=over

=item curstrm

The currently open stream

=back

=head1 METHODS

=head2 PDF::API2::Basic::PDF::Page->new($pdf, $parent, $index)

Creates a new page based on a pages object (perhaps the root object).

The page is also added to the parent at this point, so pages are ordered in
a PDF document in the order in which they are created rather than in the order
they are closed.

Only the essential elements in the page dictionary are created here, all others
are either optional or can be inherited.

The optional index value indicates the index in the parent list that this page
should be inserted (so that new pages need not be appended)

=cut

sub new {
    my ($class, $pdf, $parent, $index) = @_;
    my $self = {};

    $class = ref($class) if ref($class);
    $self = $class->SUPER::new($pdf, $parent);
    $self->{'Type'} = PDFName('Page');
    delete $self->{'Count'};
    delete $self->{'Kids'};
    $parent->add_page($self, $index);

    return $self;
}

=head2 $p->ship_out($pdf)

Ships the page out to the given output file context

=cut

sub ship_out {
    my ($self, $pdf) = @_;

    $pdf->ship_out($self);
    if (defined $self->{'Contents'}) {
        $pdf->ship_out($self->{'Contents'}->elements());
    }

    return $self;
}
