The evaluation watermark

What an unlicensed copy looks like: the evaluation watermark the library stamps on every page.

JSON write_eval_watermark.json 88 lines

This one is not a program. It is the request the document server is sent: the same page, asked for over the network by an application that writes no PDF code at all.

This is the one pair on the site rendered without a licence key, because that is what the example itself shows. Without a key the library draws every letter as a shape rather than as text, so neither of the two files holds a single word you could select or copy — on either side. What the two are held to is their pages matching dot for dot, watermark included. The library also writes each of the six lines at a stated height, where the request gives each one a rectangle and lets the line sit one line's height under the top of it.
