=head1 NAME
PDF::API3::Compat::API2 - A Perl Module Chain to faciliate the Creation and Modification of High-Quality "Portable Document Format (aka. PDF)" Files.
=head1 SYNOPSIS
use PDF::API3::Compat::API2;
#
$pdf = PDF::API3::Compat::API2->new;
$pdf = PDF::API3::Compat::API2->open('some.pdf');
$page = $pdf->page;
$page = $pdf->openpage($pagenum);
$img = $pdf->image('some.jpg');
$font = $pdf->corefont('Times-Roman');
$font = $pdf->ttfont('TimesNewRoman.ttf');
=head1 GENERIC METHODS
=over 4
=item $pdf = PDF::API->new %opts
Creates a new pdf-file object. If you know beforehand
to save the pdf to file you can give the '-file' option,
to minimize possible memory requirements later-on.
B<Example:>
$pdf = PDF::API3::Compat::API2->new();
...
print $pdf->stringify;
$pdf = PDF::API3::Compat::API2->new();
...
$pdf->saveas("our/new.pdf");
$pdf = PDF::API3::Compat::API2->new(-file => 'our/new.pdf');
