No, I've spent a full day coding to parse the content stream and to remove specific OCG layers. It works and it doesn't work. It works in the sense that the correct PDF syntax is removed. It doesn't work in the sense that for some PDFs the state operators are no longer balanced if you remove stuff like this /OC /SomeLayer BDC q some q syntax Q EMC As you can see, there are two "save state" operators in this (pseudo) PDF snippet, and only one "restore state" operator. I've written code to deal with this problem, but I can't just add 'q' or 'Q' at arbitrary places: in some cases, this results in a graphics state that is changed in a way that is not desired. Of course, I'm working on a generic solution. Your case is much easier: > Pdf files are always simple, without layers, one layer that contains the > watermark are added me. Unfortunately for you, I'm not that interested in writing non-generic code: it will work in some cases, but not in all. There is no honor in writing such code. I'm sorry that you have a deadline.
