photo_uploader

  process :resize_to_fit => [800,800]    version :big     process :resize_to_limit => [800,600]     process :convert => 'jpg'   end    version :thumb, :from_version => :big     process :crop     resize_to_fill(100,100)   end    def crop     if model.crop_x.present?       resize_to_limit(600, 600)       manipulate! |img|         x = model.crop_x.to_i         y = model.crop_y.to_i         w = model.crop_w.to_i         h = model.crop_h.to_i         img.crop "#{model.crop_x}x#{model.crop_y}+#{model.crop_w}+#{model.crop_h}"         img       end     end   end

view

<%= image_tag @photo.photo_url(:big), id: "cropbox" %>

model

  mount_uploader :photo, photouploader   attr_accessor :crop_x, :crop_y, :crop_w, :crop_h   before_create :crop_spot   after_update :crop_spot

update

#cropping spots def crop_spot   photo.recreate_versions! if crop_x.present? end

the img.crop method not change image, returns new one. either use img.crop!, edits image in place, or remove last img, edited image retured.

the crop method becomes

def crop   if model.crop_x.present?     resize_to_limit(600, 600)     manipulate! |img|       x = model.crop_x.to_i       y = model.crop_y.to_i       w = model.crop_w.to_i       h = model.crop_h.to_i       img.crop "#{model.crop_x}x#{model.crop_y}+#{model.crop_w}+#{model.crop_h}"     end   end end
