Hey, please help me! I want to add a watermark to each page only on 'input.pdf' and save it.

And you don't want to have the file in memory?
Single pages in memory is ok?
Please elaborate a bit further as im not sure i understood correctly

Yes, I want it to add on itself; a single page is okay if possible.
