Graphics, Figures & Tables ⇒ subfig captions referencing subfigures

[daviddoria]

When trying to use \subref in a subfloat caption, I am getting "Argument of caption has an extra}". I am following the subfig documentation for doing this, so I think the syntax is correct. Any ideas? An example (working and broken version) is below:

Code: Select all

\begin{figure*}
\centering
\subfloat[]{
\fbox{\rule{0pt}{2in} \rule{0.9\linewidth}{0pt}}
\label{fig:CatOcclusion:None}
}
\caption{Cat sculpture scans with varying occlusions. \subref{fig:CatOcclusion:None} No occlusion} % this is the line with the problem
%\caption{Cat sculpture scans with varying occlusions} % works
\end{figure*}
\end{document}

Also here, it works without error for me.

Perhaps post again a .log file.
Btw. better use the Code button in a forum post, the LaTeX button is for inline code.

Log file attached. (and I changed the to [code] in the original post.

Thanks you very much for your help so far!

[Stefan Kottwitz]

Very good!

In your code, you just need to protect \subref:

Code: Select all

1
\protect\subref{fig:CatOcclusion:None}

This prevents \subref from being expanded too early, when it's written to the list of figures file.

Strange, I swear I've done that before without \protect, but it indeed works now, thanks again!

[Stefan Kottwitz]

You are right, with an older caption package (of 2010) it used to work without \protect.
