Sometimes, multiple pages of a pdf have to be rotated. (As explained here for Acrobat.) Is there a way to do it in LO?
One workaround for scanned pdfs is to export to images using addon, rotate the images and compile them back using Impress.
Page rotation can be done by PDFSaM and other free softwares, but I wish to know if LibreOffice will allow it, at least in future?
