If you use the "Aa" key to change font size, it only affects text. PDF books that contain text that was extracted for photos of book pages (OCR) can have the font size of the text adjusted with "Aa", but any text that is embedded in a picture image of a book page cannot have its fonts adjusted. You can only change the size by resizing the entire image of the book page
, but that is not a function of the "Aa" font options.
