Onsite image cropping functionality with a fixed ratio with RoR,
Paperclip, S3 setup
I am looking for a way to provide a onsite image cropping functionality to
the user. However, I would only like to allow them to crop their image
with a given respect ratio. The idea is similar to the square protrait
cropper for some social website when you upload an avatar. Can anyone
suggest a solution for this? Thank you.
