giiif library is inspired by ruby gem iiif_s3 ( It serves as a generator for IIIF level 0 compatible image tiles and metadata from a collection of source images. The generated image stack can also be uploaded to Amazon S3 and used for static serving.


This library assumes that you have ImageMagick installed. If you need to install it, follow the instructions:

on OSX, brew install imagemagick should be sufficient.

If you have issues with TIFF files, try

brew update
brew reinstall --with-libtiff --ignore-dependencies imagemagick

If you plan to work with PDFs, you should also have a copy of GostScript installed.

on OSX, brew install gs

Add this line to your application's Gemfile:

gem 'giiif'

And then execute:

$ bundle

Or install it yourself as:

$ gem install giiif


If choose to upload to Amazon S3 , giiif assumes that you have an Amazon S3 account configured for use. By default, it uses the same locations that the Amazon S3 ruby library searches:

ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY'] The shared credentials ini file at ~/.aws/credentials (more information) From an instance profile when running on EC2. The SDK also searches the following locations for a bucket name and a region: ENV['AWS_BUCKET_NAME'] and ENV['AWS_REGION']
