Hi all,

I have a collection of PDFs that I will be printing at varying dimensions. Does anyone know how I could go about analysing the images embedded in the PDF to determine the 'DPI' of each image in the actual printout?

In reality, I can work out everything I need, so long as I can work out the dimensions of the 'element' that the images are in in the PDF.

Hopefully that makes sense to somebody: if not, feel free to say! I'm looking to do it with PHP in a Linux environment. I have tried with pCOS but apparently it's not possible, though I'm happy to be corrected.

If I need to pay for a library, I'm happy to do so, so long as the price, support and reliability are right.

Thanks...

PHP has a massive free image library of functions. I'm not sure if it supports PDFs but it is worth looking into: http://us.php.net/manual/en/book.image.php

Thanks wayfarer07, but unfortunately it doesn't really do what I'm after. Thanks, though.

Anyone else have any thoughts?
