I have a PDF in which every page has an image that is crooked by almost ninety degrees. Not all the same amount of rotation and some are clockwise, while some are widdershins. I don't want to wait to put it on my iPad till after the nasty task of fixing this.
I know how to find and edit the PDF in the iBooks library. Is there any downside to doing so?
It would be a bit of proctalgia to delete from iBooks and re-import after every edit. I have to re-sync either way, but I do that often anyway.
