Wow, there was a lot of discussion on this today...I'll just throw out some responses to points Jim made in case any of it is useful:

I generally like to provide as little information as possible to a constructor...helps allow use in unforeseen circumstances and makes the code using it simpler. And you can call getPdfWriter() on the template, and getPdfDocument() on that writer, so I don't really see the need to pass them explicitly even if they are needed. > As for clipping, this seems to do the trick without templates.

This is what I tried first, but it generated invalid PDF files more often than not. I may well have been missing some subtleties of the state management functions, but I've had best luck just avoiding state saves and restores altogether. > Actually, I think we are almost there.

My copyArea() actually doesn't work...what's there was a first attempt, and I moved on when it didn't work properly since none of the code I've seen uses it. It may serve as a starting point for something that does work, though; haven't played with it enough to tell. I'm pretty sure XOR mode isn't feasible; it seems fundamentally incompatible with vector graphics.
