A command line tool is preferred, but not required.
Preview and PDF Pen and dozens of other apps can delete arbitrary pages from a PDF file and save the result. The key problem I can’t solve is how to systematically detect a blank page and have it deleted. Blank is defined as no visible line or text or content.
Do you know of any tool that can detect and remove blank pages from a multi-page PDF file and be controlled by automation (script / Automator / something other than click, look, click)?
