polarius:

I've never done that, but I took a quick look at the PDF handling modules I have installed and found a couple candidates:

• Text::PDF has a Text::PDF::Pages object that can report the bounding box of a page.
• PDF::API2 has a Page object that can report the media box.
• CAM::PDF has a getPageDimensions function.

So if you have one of those packages installed, give it a go and report back.
