Typed PDF

A nursery of additional types for PDF-RS (https://github.com/pdf-rs/pdf).

It currently contains an enum for page content operations (https://docs.rs/pdf/0.7.1/pdf/content/struct.Operation.html) and a binary that will attempt to parse a set of PDF files and print operations that it can't type.

At the moment, operations have the following issues:

• Text is parsed into rust strings, if they cannot be parsed into rust strings they're considered unknown operations. This happens a lot more regularly that I had expected.

• The following operations are not implemented, they're mostly property lists and binary data:

  • BDC
  • BI
  • BMC
  • BX
  • DP
  • EI
  • EMC
  • EX
  • ID
