# How can I replace a full stop with an image?

I would like to hide an easter egg in my document by replacing the last full stop of my conclusion with a (vector) image scaled down to pass as a punctuation, almost like a microdot. Is this possible to do without too much work?

The image itself is an SVG which I have converted to a TikZ image using InkScape, but if another format is better suited for this I can convert it again. The document is going to be published as a PDF so I'm hoping that someone with a keen eye may notice and zoom in enough to see the image.

You can put \begin{tikzpicture}...\end{tikzpicture} anywhere. – egreg Jan 5 '14 at 15:15
@egreg Sure, but I want it to look like a full stop to the casual observer so it needs to be placed and scaled correctly. – David Holm Jan 5 '14 at 15:46
I usually hide some text in "white" pages with \textcolor{white}{hidden message}. – Andrestand Jan 26 '14 at 13:18

The main problem is making the fake dot sufficiently dark. I used a PDF file of a text inside a circle.

\documentclass{article}
\usepackage{graphicx}
\begin{document}
This is the end.

This is the end%
\makebox[\fontcharwd\font.][c]{%
\resizebox{\fontcharht\font.}{!}{%
\includegraphics{fakedot}% here put whatever you like
}%
}
\end{document}

Thanks! This did exactly what I wanted it to. In the end I decided to use a black silhouette to get it to look as dark as possible. – David Holm Jan 6 '14 at 10:14
