PoDoFoBrowser

PoDoFoBrowser helps users browse objects in PDF files and modify their keys. This way, it makes it possible to correct the internal structure of PDF files easily.

The program isn't too complicated when it comes to its graphical user interface. It is divided into two pieces: one that shows the background process in a command-prompt window, while the other reveals general options, like 'File', 'Tools,’ ‘Edit,' and so on.

Built in C++, PoDoFoBrowser allows users to look into a PDF file directly and edit its stream. Thanks to its HEX conversion capabilities, any text format will be encoded to HEX data. Users can add new keys in the internal structure of a PDF file. Those who want to parse text from PDFs should know that it takes some skill into inputting some specific commands on each page of the document.

PDF language is RPN-based. A command stream consists of values which are pushed onto a stack. All the commands you need to process have one parameter at most.

A catalog view mode shows the HEX data inside a PDF file into categories, like object name, value, and type. These will make it easy for programmers to find PDF details.

Obviously, users cannot import or export any files except PDF ones, since that would be counterproductive. All the developing effort was invested into building a solid PDF reader and not a universal converter.

PoDoFoBrowser is a powerful tool for those that need to parse PDF files for either images or text, or simply edit documents. Sometimes, PDF data can be hard-coded, but if you are allowed to edit it, then clearly this app will be a great friend in need. It makes it easier for you to look at the internal structure of PDF files.
