Hello!! Dragonfly is a highly customizable ruby gem for handling images and other attachments and is already in use on thousands of websites.
If you want to generate image thumbnails in Rails ...
class User < ActiveRecord::Base # model dragonfly_accessor :photo end
<%= image_tag @user.photo.thumb('300x200#') # view %>
... or generate text images on-demand in Sinatra ...
get "/:text" do |text| Dragonfly.app.generate(:text, text, "font-size" => 32).to_response(env) end
... or just generally manage attachments in your web app ...
wav = Dragonfly.app.fetch_url("http://free.music/lard.wav") # GET from t'interwebs mp3 = wav.to_mp3 # to_mp3 is a custom processor uid = mp3.store # store in the configured datastore, e.g. S3 url = Dragonfly.app.remote_url_for(uid) # ===> http://s3.amazon.com/my-stuff/lard.mp3
... then Dragonfly is for you! See the documentation to get started!
