Zynga open sources panning and zooming library for HTML and Canvas (github.com)

There's no licensing information, even the source files simply have a copyright notice but no mention of the license under which it is being distributed.

Based on https://github.com/unify/unify

This has just been announced in the JSConf EU conference in Berlin!

I would do this too. Nice way to get someone else to solve your difficult problems for free.

I set up the demos here:

http://qwan.org/scroller/demo/

(Thank you, GitHub Pages.)

Works on iPad too.

EaselJs does this with ease as well: http://easeljs.com/

Can anyone help extending this?

Trying to add Click events to this.

What the web needs is a UI demo site. You could submit a page that was a demo, and it'd have some metadata in the markup to describe it, and then that would be iframed into the site - then there'd be a header to navigate all the demos. It could be called UIpalette. Any takers?

how's this compare to something like touchscroll.js for reproducing native-style scrolling in a mobile web app? e.g. content div that scrolls with fixed footer on ios

For me the other project they released was more interesting:

https://github.com/zynga/viewporter

Shows to what extremes you need to go to get fullscreen on all the Android customizations out there, HTC, Samsung etc.

Anyway very useful for me since I cant test on all those.

Does not work in IE 8.
