Can FPDF/FPDI use a PDF in landscape format as a template?

<?php
require_once('fpdf.php');
require_once('fpdi.php');

$pdf =& new FPDI();
$pdf->addPage('L');
$pagecount = $pdf->setSourceFile('template.pdf');
$tplIdx = $pdf->importPage(1);
$pdf->useTemplate($tplIdx);
$pdf->SetFont('Arial');
$pdf->SetTextColor(255,0,0);
$pdf->SetXY(25, 25);
$pdf->Write(0, "This is just a test");
$pdf->Output('newpdf.pdf', 'F');

?>
