Problema de alineación con PHPRTF

[Highlander]

Ok tengo el siguiente codigo, estoy usando la clase PHPRTF (http://www.phprtf.com/)

El asunto es que tengo tres parrafos los cuales no he logrado alinear de ninguna manera, lo unico que nesecito hacer es dejar dos de ellos con alineacion a la izq y el tercero a la derecha.

El codigo:

Código:

<php?require_once("rtf/Rtf.php");

$parF = new ParFormat();

$rtf = new Rtf();
$header = &$rtf->addHeader('first');
$header->addImage('img/chile.png', new ParFormat('right'));

$sect = &$rtf->addSection();
$sect->writeText("<b>Concepción, $dia de $mes $ano</b>
", new Font(18), new ParFormat('left'));

$par = new ParFormat('left');
$par->setIndentLeft(4);
$par->setIndentRight(5);
$par->setBorders(new BorderFormat(1, '#000000'));

$sect->writeText('', new Font, new ParFormat());
$sect->writeText("<b> Vendedora</b>",new Font(14, 'Times New Roman', '#000080'), $par);
