Order of pages in a PDF

Hello everyone,

I'd like to change the order of pages in a pdf. I have tried to create a DDX like this:

<?xml version='1.0' encoding='UTF-8' ?>

  <DDX xmlns='http://ns.adobe.com/DDX/1.0/'>

    <PDF result='out.pdf'>

      <PDF source='AssemblerResultPDF.pdf' pages='2,1,10,4,9,5,3,11,12,13,14' />

    </PDF>

  </DDX>

it does suppress the pages that are not present in the range (here pages 6,7 and 8) but the result stays in the ascending order (here 1,2,3,4,5,9,10,11,12,13,14).

in the ddx docu there is this exampe: penultimate,4,5,1-3 but still, my result is page 1 to 5 and then (with the above pdf) page 13.

This behaviour seems strange to me. Is it normal? Is there a way to change the order of pages in a pdf.

Regards

Antoine
