Now that PDFLib.pm supports bounding boxes natively, I am trying to decide if I want to tackle writing an "as PDF" stylesheet and SAX filter. Something like... 



my $machine = Pipeline(



    # How do I ->set_stylesheet_uri("my_pdflib.xsl") here?



    "XML::Filter::XSLT", 



    "XML::Filter::PDF",



    $pdf_file,



  );







$machine->parse_uri($xml_file);
