Colorama is a Gem for extracting the most dominant and prominent colors from an image.
This Gem uses RMagick, so the ImageMagick lib must be installed.
Add this line to your application's Gemfile:
gem 'colorama'And then execute:
$ bundle install
Or install it yourself as:
$ gem install colorama
The simplest usage is extracting the information from the image's file directly:
colors = Colorama.extract_from_file('filename')and it returns a Hash containing the keys background, primary, secondary and detail.
You may also pass the level of compression to apply to the image, like so:
colors = Colorama.extract_from_file('filename', detail: :high)It accepts lowest, low, high and highest
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
