Find out Width and Height of a given PDF file

[pranaysharmadelhi]

Hi,

I am working on a project which requires the following:

User uploads a pdf file(through basic php form)

pdf is stored temporarily and the Width/Height of the pdf is checked against a matrix in database and a price is calculated and the user is sent to shopping cart for printing.

I have tried fpdi with FPDF and TCPDF but both of them require me to enter a value for a new PDF and then import an existing PDF.  ???

I am having hard time finding out how to find out widht/height of the imported pdf and also how many pages exists.

Any help would be greatly appreciated.

 

Thanks!

This is the way I do it, but you'll need to be on a linux server with Image Magick installed:

 

$command = escapeshellcmd('identify -format "%wx%h" ' . $path_to_pdf) . '[0]';
$geometry = `$command`;
list($width, $height) = split("x", $geometry);

 

Then you can access the dimensions through $width and $height.

Correct if I'm wrong, but every page in PDF file can have different dimensions, so you will need to get all of them.
