def get_font_key  # :nodoc:
  # The following elements are arranged to increase the probability of
  # generating a unique key. Elements that hold a large range of numbers
  # e.g. _color are placed between two binary elements such as _italic

  key  = "#{@font}#{@size}#{@font_script}#{@underline}#{@font_strikeout}#{@bold}#{@font_outline}"
  key += "#{@font_family}#{@font_charset}#{@font_shadow}#{@color}#{@italic}#{@font_encoding}"
  key.gsub(' ', '_') # Convert the key to a single word
