title: Is there a ready made RMagick image editor out there?
body: <p>I am about to build a basic online image editor for my web application using rails and rmagick. I did a bit of googling but couldn't find any existing solution, however I'd like to be sure before I spend a lot of time rolling my own.</p>
  
  <p>Is anyone aware of a plugin/gem that provides a pre-rolled image editor with undo/redo and minimal image degradation on multiple edits?</p>
  
  <p>Thanks!</p>
