# Example: Coffee cup

Published 2014-02-03 | Author: Mark Wibrow

It may be easy to download and use a free clipart picture of a coffee cup. However, by drawing it using TikZ we can learn something more about TikZ’ capabilities.

Here we can see the use of scopes, shifting, fadings and opacity, and applying postactions.

The code was written by Mark Wibrow and posted on TeX.SE.
