captionsfontsize
How to set the font size for captions using specific sizes (e.g.: 9pt)?
I've been trying to set the captions to 9pt using the following command:
\usepackage[font={9pt,bf}]{caption}
But it fails. The error message is Package caption Error: 9pt undefined.
On the other hand, using footnotesize (or any other) works ok.
After some headaches:
\documentclass{scrartcl}
\usepackage[edtable]{lineno}
\usepackage{caption}
\usepackage{threeparttable}
\usepackage{xpatch}
\makeatletter
\newenvironment{etabular}
{\resetlinenumber[1]\let\@centercr\relax\edtable{tabular}}
{\endedtable}
\newenvironment{etabular*}
{\resetlinenumber[1]\let\@centercr\relax\edtable{tabular*}}
{\endedtable}
\catcode`\*=11
\xpatchcmd{\threeparttable}
{\TPT@hookarg{tabularx}}
{\TPT@hookarg{tabularx}\TPT@hookin{etabular}\TPT@hookarg{etabular*}}
{}{}
\catcode`\*=12
\makeatother
\begin{document}
\begin{table}\centering
\begin{threeparttable}[b]
\caption{A simple table}
\begin{etabular}{l*{3}{c}}
& \multicolumn{1}{c}{(1)} & \multicolumn{1}{c}{(2)} & \multicolumn{1}{c}{(3)} \\
Variable 1 & 1.85\tnote{1} & 0.92 & 1.11 \\
& (0.34) & (0.24) & (0.14) \\
\end{etabular}
\begin{tablenotes}
\item[1] A note
\end{tablenotes}
\end{threeparttable}
\end{table}
\end{document}
The edtable environment should be made known to threeparttable;
however we can't pass it to the hooks, because edtable has an optional argument, so I use a "wrapper" for it;
the command \resetlinenumber is not allowed in threeparttable, so I hide it in the new environment;
a \@centercr emitted by edtable causes the infamous "Perhaps a missing \item" error, so I neutralize it;
the \threeparttable environment is patched to made the etabular environment known to it (see this answer).
Similar patches are made for the etabular* environment that internally calls \begin{edtable}{tabular*}. One has to use \TPT@hookarg instead of \TPT@hookin, in this case, like for tabular*.
Protecting the command should solve the problem:
\documentclass{article}
\usepackage{ulem}
\begin{document}
\begin{figure}
While it does work \dashuline{here}
\caption{It does not work \protect\dashuline{here}}
\end{figure}
\end{document}

captionknows only a specific set of font keywords. If you want something special you must setup the keyword first:
