Dragonfly

Build Status

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 ...

classUser < ActiveRecord::Base# modeldragonfly_accessor:photoend
<%= image_tag @user.photo.thumb('300x200#').url if @user.photo_stored? # 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'interwebsmp3=wav.to_mp3# to_mp3 is a custom processoruid=mp3.store# store in the configured datastore, e.g. S3url=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!

Dragonfly
Build Status
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 ...
classUser < ActiveRecord::Base# modeldragonfly_accessor:photoend
<%= image_tag @user.photo.thumb('300x200#').url if @user.photo_stored? # 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'interwebsmp3=wav.to_mp3# to_mp3 is a custom processoruid=mp3.store# store in the configured datastore, e.g. S3url=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!
