Prepare
Turn all pages, only the odd ones, or only the even ones by 90, 180 or 270 degrees. The fix for scans that came in sideways and duplex runs that came out upside down.
Rotate every page, or just the backs of a duplex scan.
The page rotation is set in the file; nothing is re-rendered.
See the result before downloading.
The defaults come from your file. Change a setting and the proof updates before you let go of the mouse.
