Given a PDF, how can one get the layout mode of a PDF (or relative width/height) using a PHP lib or linux command line tool?

Using http://www.tecnick.com/public/code/cp%5Fdpage.php?aiocp%5Fdp=tcpdf which can set this variable on new PDFs, but for existing pdfs from adobe.

Thought of converting pdfs to ps, or using gs in some other way - like converting it to an image first, and getting the width and height of that. Is this the best way?
