How to do it...

We will use the background package. In this recipe, you can use any LaTeX document. You may also start with the article class and add some dummy text. The code bundle for the book contains full examples. You can download it at http://latex-cookbook.net.

• Load the background package
• Set up the background using the command \backgroundsetup, with options

Here we go:

1. Load the background package:

   \usepackage{background}

2. Set up the background. Optionally, specify scaling factor, rotation angle, and opacity. Provide the command for printing in the background. We will use the \includegraphics command here, with a drawing of the CTAN lion:
