I am currently building a large iBooks project that mostly consists of piano keyboard images with some text on top. The book is vertical format only. The Images are.jpgs and the text over them (as well as assembly of the whole project) is edited on iBooks Author 2.3. I can zoom in on images only but not when they have text over them which has been applied on ibooks author. Isn't there a way to be able to zoom in on images AND text? Thank you.
