Hi

I've been tasked with reformatting a multi-page pdf from A4 to 2 x up on A3 with a border.

Using itextsharp I can create an A3-sized pdf and stamp the A4 pages to the left and right of the page.

What I can't seem to find a way to do is re-size the A4 pdf to something a bit less in order to centralise the left/right 'panes' of the A3 sheet and therefore create a border.

Does anyone know how to scale a pdf to (say) 98% of it's size?

Everything I've been able to research either leads to cropping it, which isn't what I want at all, or converting to an image first, whch I also want to avoid.

Thanks!
