A client is telling me that there is a way to add these functionalities to an existing indesign file but I cannot figure out how. They would like to have the exact same features that an iBook has, but on a standalone pdf. Is this possible through indesign, or do I need a 3rd party software? I did manage to speak to a company that does this, and all they told me was that they take the indesign file, which is a horizontal layout of a book, and add the swipe and zoom functionality that exactly mimics those of ibooks.
Not in PDF. That sounds like DPS.
