You are here: Browse Railsplugins Rotation Fu
Rotation is a simple plugin that will read your exif orientation data and rotate your image accordingly. Currently this is made only to work with mini_magick, although I will be adding as many processors as I can possibly think of as time goes on.
This assumes that you are using attachment_fu to handle your uploads and so therefore will have access to all the standard attachment_fu attributes.
Just put rotation_fu in your model name and your images will automagically be rotated if they have the embedded exif data.
Example:
class Photo < ActiveRecord::Base
rotation_fu
end
