There's zero documentation on this. How does saveIncremental work? I've tried loading a document I created, reading it in, adding a page, and then calling saveIncremental.... and nothing happens. The file is unchanged.
Also, why are both an input and output stream required? I've looked through the code, but there aren't any comments and I will need a better understanding of how everything works together before I can make heads or tails of it. Charles.
