Reply To: Horizontal scrolling. Help with large images!

That is a good question, I’m pretty sure this is not possible straight out of InDesign and you will need to find a developer or company that could help you with horizontal scrolling. What you are seeing currently is how most images on an e-readers are set to display by most developers out there, everyone fits them to the view port. I want to say that you might have to look into non-linear content in ePub3 to do something like what you are wanting, but even then I’m not sure if it can do everything you are wanting. This is something that will need to be hand coded by an ebook developer and I might call up eBook Architects or Aptara to see if they can help you achieve this and let you know what is or isn’t possible.
