I'm aware the option to preset International Paper (such as A4) for New documents.
So I'm looking for similar/same option, but for the existing document without having to hardcode millimetres and dpi in Canvas Size? Or having creating new document and re-pasting and resizing it there?
Is there any simple option for setting page format (A4) and page orientation (e.g. landscape) for existing image in order to save it as PDF?
I'm using CS6, but any further version is fine as well.
