(1) Didn't you ask me this directly a couple of weeks ago, and I asked you what you for clarification? I don't recall seeing such clarification, but I will admit to being many hundreds of messages behind (I'm about 800 "conversations" behind on ruby-talk). (2) I strongly recommend against trying to *extend* (e.g., monkeypatch) PDF::Writer. The internals are pretty much guaranteed to change in 2007. If you need a new PDF "object", then you will either need to (a) work with me or (b) monkeypatch. (b) has already been pointed out as a bad idea. (3) The best way to extend PDF::Writer is to make a "consumer" of PDF::Writer. -austin -- Austin Ziegler * halostatue@gmail.com * http://www.halostatue.ca/ * austin@halostatue.ca * http://www.halostatue.ca/feed/ * austin@zieglers.ca
