Graphics, Figures & Tables ⇒ Subfig: aligning wide captions and narrow images

[jasonsewall]

When trying to put several very narrow images in a figure with subfloat, I'm having trouble getting the captions to look good. By default, they are flowed inside a box the same width as the images, which looks bad. If I tweak the width of the caption via \captionsetup, the each caption and image pair is no longer aligned (horizontally)

Example:

I have a new really tall, narrow image, like so:

Code: Select all

$ ppmpat -squig 50 1000 | pnmtopng > squig.png

I have a .tex file like so:

Code: Select all

\documentclass{article}
\usepackage{graphicx}
\usepackage{subfig}
\pagestyle{empty}
\begin{document}
\begin{figure}%
  \centering%
  \subfloat[This is a pretty long caption for such a narrow image, but I need to say a lot!]{\includegraphics[height=8in]{squig.png}}%
  \hspace{1.5in}%
  \subfloat[This is also a pretty long caption for such a narrow image, but I need to say a lot!]{\includegraphics[height=8in]{squig.png}}%
\end{figure}
\end{document}

Long, narrow captions too, obviously a problem. So, I add

Code: Select all

\captionsetup[subfloat]{width=1.25in,justification=centering}%

But that doesn't seem to fix the problem. It looks like \includegraphics assumes the image will take up the whole box, so it doesn't center it.

Adding

Code: Select all

\hspace{1cm}

just before the \includegraphics makes things look better, but that's not very satisfying.

Any thoughts?

I have two solutions for this in mind:

1. Put the images in a parbox where you can provide a width parameter.

2. When using the subcaption package and \subcaptionbox (instead of subfig package and \subfloat) one can alter the width of the \subcaptionboxes. See subcaption manual for an example.
