Ruby on Rails Ajax rubberband

Question

I want my users to be able to do a rubberband selection in a image for a Ruby on Rails application. Has anyone seen any good plugins that do this or make it easy for me to implement it?

Answer 1

I played around with an image cropper that has that feature, and it uses Prototype, so it should be good to go for ROR. The code is pretty easy to figure out if you just want the elastic band element.

If you want to roll-your-own it's not too hard to glue a Scriptaculous Draggable object to a DIV and resize/move the DIV. See my crappy demo.
