  attr_reader :thickness

  def initialize(c, thick, t)
    @c = c
    @thick = thick
    @t = t
  end
end

class Circle
  attr_reader :radius
  attr_reader :brush

  def initialize(r, b)
    @radius = r
    @brush = b
  end
end

class Piece
  include Aws::Templates::Utils::Parametrized

  parameter :picture, :transform => as_rendered(
    # Render Type
    Graphics::Renders::JPEG,
    # parameter section for the render
    format: :base64
  )
end

i = Piece.new(picture: Circle.new(10, Brush.new(:red, 2, :dots)))
i.picture # => <rendered representation>
