I have a text book that i would like to conver into an Ipad format. It is currently written in Quark. It' s a very large file with many photo, diagram, illustrations and tables. I've heard of epub and calibre but wondered what happens to all the formatting from the original file in quark? Does it stay the same or do we lose the formatting therefore i would have to reformat the book. It's also in a PDF file. Can an Ipad read PDF? IF it's in PDF can the textbook be sold on the Ibook Store? Can Quark also conver to AZW format (kindle)? Same question: Would i lose the formatting?
