# Using a different font in overpic

I'm using the overpic package in the memoir class to include figures and superimpose text on them. Is there a simple way to tell overpic to use a different font than the main font of my text? (I still want the figure captions to be in the main font, though.)

Here's a MWE:

\documentclass[11pt,a4paper]{memoir}

\usepackage{fouriernc} % use the Arev font
\usepackage{overpic} % use the overpic package

% caption images outside the figure environment
\newfixedcaption{\figcaption}{figure} \captionnamefont{\normalfont} \captiontitlefont{\normalfont}

\begin{document}

This is the font of my main text.

\begin{center}
\begin{overpic}[width=0.5\textwidth]{./myfig.pdf}
\put(10, 10){This should be a different font}
\end{overpic}
\figcaption{This should be the same font as my main text.}
\end{center}

\end{document}

• Just say, for instance, \put(10,10){\sffamily This is in the sans serif font}; edit your question if this isn't what you have in mind. – egreg Feb 17 '12 at 22:10
• This is exactly what I had in mind, but is there a way to define a macro so that every \put command in overpic automatically switches to some font? (So that I don't need to write something like \sffamily in every \put in the document...) Thanks! – jamaicanworm Feb 18 '12 at 2:23
• \usepackage{etoolbox} and then \AtBeginEnvironment{overpic}{\sffamily} should work. – egreg Feb 18 '12 at 9:56

You could redefine \put to insert \sffamily (or whichever font selection) automatically by inserting the following in your document preamble:

\let\oldput\put
\def\put(#1,#2)#3{%
\oldput(#1,#2){\sffamily #3}%
}


Here's a minimal example:

\documentclass[11pt,a4paper]{memoir}
\let\oldput\put
\def\put(#1,#2)#3{%
\oldput(#1,#2){\sffamily #3}%
}
\usepackage{fouriernc} % use the Arev font
\usepackage{overpic} % use the overpic package

% caption images outside the figure environment
\newfixedcaption{\figcaption}{figure} \captionnamefont{\normalfont} \captiontitlefont{\normalfont}

\begin{document}

This is the font of my main text.

\begin{center}
\begin{overpic}[width=0.5\textwidth]{tiger.pdf}
\put(10, 10){This should be a different font}
\end{overpic}
\figcaption{This should be the same font as my main text.}
\end{center}

\end{document}

• Thanks! In my actual document, though, most of the text in \puts is actually in math mode (inside \$s), so the sffamily font doesn't help distinguish it... Is there another font I can use with a different math mode font than Arev? – jamaicanworm Feb 18 '12 at 16:35
• @jamaicanworm: Do you have a variety of serif and sans-serif math fonts going on in your document? If not, the sfmath package (or sansmath) might be of help. – Werner Feb 18 '12 at 16:43
• I added \usepackage{sansmath} to the top of the document, and replaced \sffamily with \sansmath, and it's working great now! – jamaicanworm Feb 18 '12 at 16:53
