PDF watermark add/remove image

[seagrady2]

Is this possible to add a sample of this to the play ground if it is in fact possible? I've been having a difficult time taking the existing samples and modifying them to be able to add a watermark that sits on top of a page and then remove this watermark at a later time. I have quite a bit of faith that this is possible using the PDF writer but have had no luck in getting anything to work.

The main issue is with adding a watermark is that when doing a copy context and merging pages, the original content is always behind the new content (which makes sense).

When trying to add a watermark using the ModifiedPage I am also seeing that the watermark does not sit on top of the original content.

Has anyone dealt with any of these problems? I will continue to post code here as I clean it up.

I also resolved this by using the modifier. I am having issues however loading the trailer information from a modified pdf, the trailer always is loaded as empty with no additional information directory even though I am able to read the additional info in adobe.

Have you been able to make more progress with this?

Nah we bailed and ended up using foxit pdf reader. Though we did implement this on the pdf directly, it had bugs and ended up being a main consideration for going with pdf software package that comes with maintenance
