Just some code that I threw together to play around with CarrierWave's image manipulation

processing_with_carrierwave.rb

require 'rubygems'
require 'carrierwave'
require 'fileutils'

# needed for the RMagick module in CarrierWave
def current_path
  @current_path
end

include CarrierWave::RMagick

original_path = "/Users/kevinsmith/Desktop/carrierwave/images"
modified_path = "/Users/kevinsmith/Desktop/carrierwave/modified"  
w = 262
h = 262

Dir.chdir(original_path)

Dir['*'].each do |f|
  FileUtils.cp(File.join(Dir.pwd, f), modified_path)
  @current_path = File.join(modified_path, f)
  
  #resize_to_fit(w, h)
  resize_to_fill(w, h, ::Magick::NorthWestGravity)
  #resize_and_pad(w, h, :transparent, ::Magick::CenterGravity)
  #resize_to_limit(w, h)
end
