Paperclip::Ghostscript

Add support to Paperclip to generate JPG thumbnail images from Ghostscript supported files (e.g. Adobe PDF)

Add this line to your application's Gemfile:

gem 'paperclip-ghostscript'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paperclip-ghostscript

Paperclip::Ghostscript needs access to the Ghostscript binary ("gs"). To determine the location of the binary, in Linux, run which gs from the command line. It will return a path, such as /usr/local/bin/gs.

Add the processor to your model:

  class Agreement < ActiveRecord::Base
    has_attached_file :document, styles: {
      thumb: { geometry: "150x150", format: "jpg" }
    }, processors: [:ghostscript]

  end

Which will produce a thumbnail JPG of the first page of the PDF.
