Overview

A physical file with a UID.

Files are usually created via an Attachment instance. You can call processing methods on file instances. This will save the file and return the new metadata hash.

file = Paperdragon::File.new(uid)

metadata = file.reprocess! do |job|
  job.thumb!("16x16")
end
