DESCRIPTION
    Template::Flute::PDF is a PDF generator based on Template::Flute and
    PDF::API2.

  OUTPUT

    simply leave out the file parameter when creating the

       $pdf = Template::Flute::PDF->new (template => $flute->template(),
                                         file => 'invoice.pdf');

       $pdf_as_string = $pdf->process();

BUGS
    Certainly a lot, as converting from HTML to PDF is quite complicated and
    challenging.

    Please report any unknown bugs or feature requests to
    `bug-template-flute-pdf at rt.cpan.org', or through the web interface at
    http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Template-Flute-PDF.

  KNOWN BUGS
    Background color
        Using background color hides text.

    Vertical align
        We currently support only aligning to top or bottom of the available
        space. This is in contradiction to HTML, where the default vertical
        align is baseline (of the text).
