To-Do List
==========
- Binary data/strings: needed for certain values, particular for the File ID
and user/owner passwords
- Copy methods for array, dict, object, page
- Reference streams
- Read trailer dict
- All of the object read/write code
- All of the stream read/write code
- Page create method
- Write out trailer
- How to handle object references between documents, i.e., if I copy a page from
one PDF to another, there are a bunch of resources that also need to be
copied. A dictionary with an object reference can't be copied directly as the
object number in the new PDF will likely be different than the old one.
- Security handlers (RC4 + AES, MD5 + SHA-256) for reading encrypted documents.
- Signature generation/validation code
- Documentation
- VS project
- Run through code analysis tools
