Get layout mode (landscape or portrait) pdf from php / linux

Question

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

Using http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=tcpdf , which can set this variable in new PDF files, but for existing pdf files from adobe.

The idea of ​​converting PDF files to ps or using gs in some other way - for example, first convert it to an image and get the width and height. Is this the best way?

        $result = $this->proc( $cmd );
        list($width, $height, $type, $attr) = getimagesize($complete_file_path.'/'.$pngfilename);

Big gun, but no other suggestions. I used the iText Java library to process pdf files.

Note that, as far as I know, there is no such thing as PDF layout mode or size. PDF is a set of pages, each of which has a media box that determines the size of the printed page. However, this property can be inherited by a page from previous pages, if not defined. See PDF Help for more information .
