No I didn't. Anyway I try to create a pdf.php using msword.php as a
template, but it
doesn't work (I get a blank window). Here it is:

<?php

class MIME_Viewer_pdf extends MIME_Viewer {

    function render($params = null)
    {
        global $mime_drivers;

        $tmp_pdf   = Horde::getTempFile('pdf');
        $tmp_output = Horde::getTempFile('pdf');
        $tmp_dir    = Horde::getTempDir();
        $tmp_file   = str_replace($tmp_dir . '/', '', $tmp_output);

        $version = explode('.',
exec($mime_drivers['horde']['pdf']['location'] . ' --version'));
        if (count($version) > 2 && ($version[0] > 0 || $version[1] >= 7)) {
            $args = " --targetdir=$tmp_dir $tmp_pdf $tmp_file";
        } else {
            $args = " $tmp_pdf $tmp_output";
        }

        $fh = fopen($tmp_pdf, 'w');
        fwrite($fh, $this->mime_part->getContents());
        fclose($fh);

        exec($mime_drivers['horde']['pdf']['location'] . $args);

        if (!file_exists($tmp_output)) {
            return _("Unable to translate this PDF document");
        }

        $out = fopen($tmp_output, 'r');
        $data = '';
        while (($rc = fgets($out, 8192))) {
            $data .= $rc;
        }

        return $data;
    }

    function getType()
    {
        return 'text/html';
    }

}

Is it something obvious I am doing wrong?
