  :output_height  => 600,
  :custom_id      => '12345',
  :format         => 'png',
  :delay          => 1000
}
client.save_picture('/tmp/my_picture.png', options)

puts File.exists?('/tmp/my_picture.png')
# => true

  :format         => 'png',
  :delay          => 1000
}
response = client.take_picture(options)
