#prepare(original, result) ⇒ Object

Copies the file from original path to this outlet path.

prepare( original, result )

This method SHOULD be overridden in the outlet block. Example:

class NewAdapter < Nozzle::Adapter::Base
  outlet :thumb do
    def prepare( original, result )
      `convert #{original} -thumbnail x96 #{result}`
    end
  end
end

In the example system convert is called to resize the original file and save it’s smaller version in result path.
