You could use the optional argument b
to the minipage
environments to align the images at their bottom, this way the caption would be side by side. At least you did'nt say if you want the images aligned in another way. Though, a common baseline at their bottom would be good, especially as their captions are aligned.
Here's an example using the caption
package:
\documentclass{article}
\usepackage[labelfont=bf]{caption}
\usepackage[demo]{graphicx}
\begin{document}
\begin{figure}[ht]
\begin{minipage}[b]{.4\linewidth}
\centering%
\includegraphics[width=140pt]{test}
\captionof{figure}{First image}
\end{minipage}%
\hfill%
\begin{minipage}[b]{.5\linewidth}
\centering%
\includegraphics[width=180pt,height=50pt]{test}
\captionof{figure}{Second image with caption}
\end{minipage}
\end{figure}
\begin{figure}[ht]
\centering%
\includegraphics{test}
\caption{Another figure}
\end{figure}
\end{document}
Output:
Using the tiny capt-of
package would be sufficient. The \captionof
command is important. As you can see, the numbering of the subfigures matches the numbering of normal figures.
I just ran into the same issue. (It's really annoying when trying to produce print-quality preprint versions of the paper.) Poking around in pnastwo.cls, I found the following fix:
Find the first line in pnastwo.cls which says
\ifx\@captype\xtable
Change this to
\ifx\@captype\table
Alternatively, if you don't want to touch the class file, you can
put the following into the preamble of your document:
% Fix wierd behavior which prevents table captions from appearing for
% tables in the body of the article
\makeatletter
\long\def\@makecaption#1#2{%
\ifx\@captype\table
\let\currtabcaption\relax
\gdef\currtabcaption{
\tabnumfont\relax #1. \tabtextfont\relax#2\par
\vskip\belowcaptionskip
}
\else
\vskip\abovecaptionskip
\sbox\@tempboxa{\fignumfont#1.\figtextfont\hskip.5em\relax #2}%
\ifdim \wd\@tempboxa >\hsize
\fignumfont\relax #1.\figtextfont\hskip.5em\relax#2\par
\else
\global \@minipagefalse
\hb@xt@\hsize{\hfil\box\@tempboxa\hfil}%
\fi
\fi
}
\makeatother
One additional comment: once this bug is fixed, you'll almost certainly run into another issue which you'd want fixed if you use the PNAS two-column class to produce production-quality output: Unless you define floats with the h "here" placement, it loses the labels, so all cross-referencing of figures and tables breaks. Here is the fix, for direct pasting into the document preamble. You can also patch up the macro \DonormalEndcol pnastwo.cls, it's the same mistake 6 times over...
% And another fix. PNAS class loses the label of floats unless they
% were defined with the [h] option (so not really floats at all). It
% all comes down to wrong scope in the following routine which pushes
% out the floats onto the page. This is the fixed version:
\makeatletter

SCfigure
has two optional arguments. If you use the second one, you must also use the first:
