Open Seadragon: Download currently displayed image in Viewer

I'm using Open Seadragon and loaded multiple images into the viewer with

tileSources: ['http://url.com',
              'http://url.com',
             'http://url.com',],

The files that I linked in tileSources are all json but I want to download a jpg image. How can create a function that downloads the currently viewed image?

You said you wanted the full high-resolution version of the image. I would suggest looking at the "Dezoomify" browser extensions for Firefox (https://addons.mozilla.org/en-GB/firefox/addon/dezoomify/) and Chrome (https://chrome.google.com/webstore/detail/dezoomify/iapjjopjejpelnfdonefbffahmcndfbm/related?hl=en). I am not a web developer but I came across these browser extensions when I wanted to download a zoomable image that was created using the Open Seadragon library. It would have been nice if there had been a button on the site to download / generate the full resolution image but now that I am aware of the Dezoomify browser extension I feel like my problem is solved.

Do you want the exact view that's in the viewer at this moment? If so, you can copy the contents of the HTML canvas at viewer.drawer.canvas.

You might also check out https://github.com/KTGLeiden/Openseadragon-screenshot.

If you want the full high-resolution version of the image (not just what's in the viewer at the moment), I'm not aware of anything that does that.
