=head1 NAME

PDF::API2::Lite - (do not use)

=head1 SYNOPSIS

    $pdf = PDF::API2::Lite->new;
    $pdf->page(595,842);
    $img = $pdf->image('some.jpg');
    $font = $pdf->corefont('Times-Roman');
    $font = $pdf->ttfont('TimesNewRoman.ttf');

=head1 DESCRIPTION

This class is unmaintained (since 2007) and should not be used in new code.  It
combines many of the methods from L and L into a
single class but isn't otherwise any easier to use.

There have been many improvements and clarifications made to the rest of the
distribution that aren't reflected here, so the term "Lite" no longer applies.
It remains solely for compatibility with existing legacy code.

is in user-space coordinates which is subject to
transformations which may have been specified beforehand.

Per default this has a 72dpi resolution, so if you want an
image to have a 150 or 300dpi resolution, you should specify
a scale of 72/150 (or 72/300) or adjust width/height accordingly.
