def bounding_box
  require 'perfect_shape/rectangle'
  Rectangle.new(x: min_x, y: min_y, width: width, height: height)
end

#center_point ⇒ Object

Center point is ‘[center_x, center_y]` Returns `nil` if either center_x or center_y are `nil`

def center_point
  [center_x, center_y] unless center_x.nil? || center_y.nil?
end

#center_x ⇒ Object

center_x is min_x + width/2.0 by default Returns nil if min_x or width are nil
