how to resize-to-limit already saved img?

Question

I uploaded images by using CarrierwaveUploader and I wanted to resize_to_limit so I enabled RMagick in Carrierwave.

class Word < ActiveRecord::Base
  ...
  mount_uploader :image, ImageUploader
end

class ImageUploader < CarrierWave::Uploader::Base

    include CarrierWave::RMagick
    storage :file

    def store_dir
      ...
    end

    def filename
      ...
    end

    version :thumb do
      process :resize_to_limit => [400, 400]
    end
end

Newly uploaded images are resized-to-limit, but i don't know how to apply resize-to-limit for already saved images.

Looks like you want the recreate_versions! command
