The evaluation watermark

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

Every other sample on this site is written with a licence key set. This one is the opposite: with no key, the library writes an evaluation copy and marks every page as one. It is here so that what you get before you buy is visible before you download anything.

In every other respect the evaluation build is complete: the same layout, the same tables, the same archival files. The watermark is the only difference, and setting a licence key removes it without changing a line of code.

What this example shows

  • The watermark an unlicensed copy carries on every page.
  • Everything else identical to a licensed document.
  • One line of code between an evaluation and a file with no watermark.

The code, in full

The same document is written twice, once in each language. Both files are shown in full, with the code coloured on the server, and can be copied in one click.

The document itself

The same document is written in each of these languages. Open the one you want to look at.

What this document weighs

This document weighs 81,420 bytes, and weighed exactly as much before.

An evaluation copy draws its text line by line rather than with a font, so it carries no font and there was nothing in it to take out. See every document measured.

Examples near this one

A pack built on three supplied sheets

A supply agreement standing on three PDF files the customer sent: a headed sheet under the front page, a plain sheet under every page the schedule runs to, and a page of conditions that goes in whole.

An interactive form

A form a reader fills in: text boxes, a check box, a drop-down, radio buttons.

An archivable PDF/A-3 form

A form that is also a PDF/A-3 file: every field already drawn, with a visible frame, expecting nothing from the reader's software.

A tagged list whose column is a picture

A parts list whose first column is a picture rather than a word. Each picture is marked as one and carries the words a reader hears in its place, so nothing in the list is lost on somebody who cannot see it. Validates as PDF/A-3a and PDF/UA-1.

Glossary

watermark
Wording printed across the page itself, saying the document was made with a free account. It cannot be removed from the file; a paid tier simply never puts it there.
