Hey everybody,

I'm really new to openseadragon and try to eloberate if openseadragon is the right tool to use for my usecase.

I have build a "flipping-page" project with turnjs v3.0 ( My "book" uses canvas elements for each page.
I know would like to implement openseadragon so that the "book"-container is zoomable and each page of the book is loaded as a deepzoom image.
My Markup for my flipbook needs to look like this:

<div id="flipbook"> 
  ...(for each page one canvas element) 

Is it possible to add one openseadragon container and multiple canvas elements inside of it? So that my whole "book"-container is zoomed and the "flipp"-function is still useable?

@Flexflexible_twitter Cool! Seems like a neat idea. How are you imagining people would zoom? Just zooming on the page once you've turned to it?
I don't know how you would integrate it... one thing to try would be to make each page its own OpenSeadragon viewer; it'd be interesting to see if that worked. It might not perform well if there are lots of pages, but probably worth a try.
Another option might be to swap an OSD viewer in when the page settles, though that might conflict with the page curl affordance

Another option might be for the OSD to be like a "light box" that you access by clicking on a page; it would fill the window and allow you to zoom on top of the book
Btw, how big are your images? If they are small enough, maybe OSD doesn't make sense
