I have a book that's made up of a bunch of .tif images. I have all the individual .tif files, and a pdf that's just them all put together. I'm trying to make a .epub file for the book. When I try to convert from the pdf in Calibre, it creates a "Document Outline" table of contents at the end of the book that just lists the names of each individual .tif. I don't want the Document outline at all. How can I remove it?
