How to save rotated Adobe pdf file?
I'd like to rotate by 180 degrees each page in a high-resolution .pdf, but don't know how. In ImageMagick, using 'convert -flip -flop' lowers the resolution significantly, while increasing the file size slightly. This also happens (to a lesser extent) in LibreOffice, an example of open-source PDF editors. Any ideas, besides buying Adobe Acrobat? (which may or may not solve the problem!)
