How to: Process original image

How to: Process original image

Example

This uploader will process orginal image after store. It will resize image with max width 1200px. You can add this to your existing uploader and later reprocess all uploads with standard foo_model.file.recreate_versions! . It will reprocess original images too. You cannot restore original images after this.

class FileUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick
  storage :file

  after :store, :process_original

  # Developer must ensure mogrify exists and available in host OS
  # Replace "-resize 1200" with your settings
  def process_original(new_file)
    if version_name.nil?
      system("mogrify -resize 1200 #{file.file}")
    end
  end
end

Please ensure system command "mogrify" exists in target OS

$ which mogrify
/usr/bin/mogrify
