Module: Spotlight::ImageDerivatives

Included in:
BlacklightConfiguration, ItemUploader, Resources::Upload, SolrDocument::SpotlightImages::Versions
Defined in:
app/models/concerns/spotlight/image_derivatives.rb

Overview

Include Spotlight::ImageDerivatives in a class or module to get the derivative configurations in #spotlight_image_derivatives. A new derivative could theoretically be added by putting the following in an initializer. Spotlight::ImageDerivatives.spotlight_image_derivatives << {

version: :my_version,
field: :my_field,
lambda: lambda {|_|
  version :my_version do
    process :resize_to_fill => [30,30]
  end
}

}

This will then create that new CarrierWave version in any class that extends this module and calls the apply_spotlight_image_derivative_versions class method described below.
