HexaPDF is now able to use a TrueType font to generate content. There are still some limitations, like the missing support for subsets but most things work quite well already. Complete integration into the Canvas and font selection API is also not done yet.

The attached script generates a PDF showcasing all available glyphs defined in a font as well as a sample text containing characters from the Unicode BMP as well as from other Unicode planes.

  def initialize(attributes)
    attributes.each do |attribute_name, attribute_value|
      ##### Method one #####
      # Works just great, but uses something scary like eval
      # self.class.class_eval {attr_accessor attribute_name}
      # self.instance_variable_set("@#{attribute_name}", attribute_value)

      ##### Method two #####
      # Manually creates methods for both getter and setter and then
