This commit introduces the ability to parse the document catalog dict, as well as the page tree and individual pages. Pages obviously aren't fully parsed, as we won't care about most of the fields until we start actually rendering PDFs. One of the primary benefits of the PDF format is laziness. PDFs are not meant to be parsed all at once, and the same is true for pages. When a Document is constructed, it builds a map of page number to object index, but it does not fetch and parse any of the pages. A page is only parsed when a caller requests that particular page (and is cached going forwards). Additionally, this commit also adds an object_cast function which logs bad casts if DEBUG_PDF is set. Additionally, utility functions were added to ArrayObject and DictObject to get all types of objects from the collections to avoid having to manually cast. |
