    Versatile PDF creation and manipulation for Ruby

    Regarding TrueType font support: What I meant was that the library isn't a full TrueType font library but contains just the parts necessary for PDF supports. So what it can do is write a subset of a TrueType file because that's needed. But it can't serialize any arbitrary TrueType tables and it only handles those TrueType tables needed for displaying text in PDF. More advanced things like glyph positioning based on the language and characters in question is also not supported but may be in the future. Have a look at https://github.com/gettalong/hexapdf/tree/master/lib/hexapdf/font/true_type/ to see the implementation. All the things in this folder and below should be independent of PDF.
