How it works

Rotate all pages, only odd/even pages (useful when a double-sided scan came out upside down on one side), or a custom list like 1,3,5-7.
Landscape-only mode rotates just the pages that are wider than they are tall — the usual fix for a scan where a few sideways pages got mixed in.
Rotation is applied on top of any existing rotation the page already has.
