I want the caption for each subfigure to be on one line because it isn't so long that it should line-wrap. Is there any way I can force it to be on one line?
Here is a minimum working example:
\documentclass[a4paper,12pt]{article}
\usepackage[demo]{graphicx}
\usepackage{subcaption}
\usepackage{epstopdf}
\begin{document}
These captions will look very bad.
\begin{figure*}[thp!]
\centering
\begin{subfigure}[t]{0.5\textwidth}
\centering
\centerline{\includegraphics[height=8cm, width = 13cm]{file.eps}}
\caption{This long caption should fit on one line still}
\end{subfigure}
\begin{subfigure}[t]{0.5\textwidth}
\centering
\centerline{\includegraphics[height=8cm, width = 13cm]{file.eps}}
\caption{This long caption should also fit on one line}
\end{subfigure}%
\end{figure*}
\end{document}
