Intro
Kropper is a free, open-source image cropper for Rails apps by Jonathon Wolfe. It was inspired by the image-cropping UI in Apple's iChat and is best suited for cropping of user profile images or other instances where you want cropped images to have a specific aspect ratio. This demo app manipulates images that are stored with the attachment_fu plugin, but it would be easy to modify it to crop images stored in some other fashion.
Features
- It's easy to use, and it looks pretty sweet.
- Very little Ruby code to add to your app, especially if you're using attachment_fu to handle images.
- It works with either ImageScience or Rmagick as the backend image processor.
- It's been tested in IE 6 & 7, Firefox 1.5 & 2, and Safari 2.0.4.
- You can decide whether images are just cropped to the shape of your cropping stencil, or also resized to actual size of the stencil.
- You can easily change the UI around—the appearance, size, and shape of everyting, including the cropping canvas and cropping stencil, are defined with CSS.
