PDFFile instances have a Root dictionary attribute which is the file's "document catalog" object tree. You really need to have the PDF reference book at hand to understand its structure (free to download from Adobe.com). All objects in the tree are wrapped in the Object class so as to permit 'lazy loading'. Call the value() method on Objects to get the underlying pythonized object. For lists and dictionaries, normal [] access is implemented accordingly. Note that Name objects look like strings, which is generally what you want. All non-image filters have been implemented, and encrypted documents with either empty or supplied user password are supported. Only revision 2 standard encryption is fully implemented. External file streams are not supported. This module is not particualrly efficient at accessing the PDF document, so I wouldn't recommend using it as the basis of a file transformer or viewer. Instead, it is probably most useful as a way of accessing information about PDF documents, such as the TOC, or the security bits.
