I have a few narrow figures for which I want to center the caption. I have to use a LaTeX template from Springer (svmult.cls). This makes captions left-aligned by default. I took a look at this question which suggest to add the captions package and then locally use

\captionsetup{justification=centering}

But this has no effect in this case. The relevant part from the class file looks like this:

\usepackage{subfig}
% redefininition of the captions for "figure" and "table" environments
%
\@ifundefined{floatlegendstyle}{\def\floatlegendstyle{\bfseries}}{}
\def\floatcounterend{\enspace}
\def\capstrut{\vrule\@width\z@\@height\topskip}
\@ifundefined{captionstyle}{\def\captionstyle{\normalfont\small}}{}
\@ifundefined{instindent}{\newdimen\instindent}{}

  ext@#1\endcsname}{#1}{\protect\numberline{\csname
  the#1\endcsname}{\ignorespaces #2}}\begingroup

As far as I understand, it merely defines extra captions for figures composed of two horizontal sub figures?

Any idea why the captionsetup doesn't work in this case, and if there is a work around (perhaps using something in subfig as that package is already included).


EDIT: Here is a minimal example:

\documentclass[graybox]{svmult}
\begin{document}
\begin{figure}
\centering
My graphics
\captionsetup{justification=centering}
\caption{My caption}
\end{figure}
\end{document}

Where svmult.cls is available from Springer.

    If you have to use the template, then you're not supposed to fiddle with its settings. – egreg Jul 15 '14 at 15:38
  • Well, but I have a figure which really is 33% of \textwidth, believe me it looks crap. I would just like to know why nothing in captionsetup has any effect. – Emit Taste Jul 15 '14 at 15:42
  • Can you add a minimal example of your code? – egreg Jul 15 '14 at 15:43
  • @egreg - I edited the question. – Emit Taste Jul 15 '14 at 15:48

Use a minipage.

\documentclass[graybox]{svmult}
\begin{document}
\begin{figure}
\centering
\begin{minipage}{.33\textwidth}
\centering

This text is supposed to substitute the image
in this figure environment

\caption{My caption}
\end{minipage}
\end{figure}
\end{document}

Adding \usepackage{caption} results in a center-aligned caption

enter image description here

\documentclass[graybox]{svmult}
\usepackage{caption}

\begin{document}
\begin{figure}
\centering
My graphics
\captionsetup{justification=centering}
\caption{My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv My caption dfhu orifv }
\end{figure}
\end{document}
