Library of simple image manipulations - replicating the behaviour of morandi-js.
Install liblcms2-utils to provide the jpgicc command used by Morandi::ProfiledPixbuf. Also ensure that your host system has imagemagick installed, which is required bi the colorscore gem.
Add this line to your application's Gemfile:
gem 'morandi'
And then execute:
$ bundle
Or install it yourself as:
$ gem install morandi

- in_file is a string
- settings is a hash
- out_file is a string

Since this gem depends on the liblcms2-utils library, which can be awkward to install on some operating systems, we also provide a development docker image. A Makefile is also provided as a simple CLI. To build the image and run the container, type make from the project root. The container itself runs guard as its main process. Running the container via make will drop you into the guard prompt, which will run the test suite whenever any of the source code or tests are changed. The tests can be kicked-off manually via the all command at the guard prompt. Individual test can be run using the focus: true annotation on an example or describe block. If you need to access a bash shell in the container (for example, to run rubocop), use the command make shell.
