Hello, thanks for working on this package.

Unfortunately, I have an issue when not including 'subfigure in the org-latex-caption-above list.
In particular, the \centering command is written below the subfigure commands, all the way below right before \end{figure} and therefore doesn't affect the images.

See for example the org snippet

#+NAME: fig:runway-example-both
#+CAPTION: Example of /content/ and /style/ decomposition.
#+ATTR_LATEX: :environment subfigure :width 0.45\textwidth :align c
|  [[./figs/airstrip_imgs.png]]  |  [[./figs/airstrip_imgs2.png]] |
| Maintaining content, changing style. | Maintaining style, changing content. |

and the generated latex snippet

\begin{figure}[htbp]
\begin{subfigure}[c]{0.45\textwidth}
\includegraphics[width=.9\linewidth]{./figs/airstrip_imgs.png}
\caption{Maintaining content, changing style.}
\end{subfigure}
\begin{subfigure}[c]{0.45\textwidth}
\includegraphics[width=.9\linewidth]{./figs/airstrip_imgs2.png}
\caption{Maintaining style, changing content.}
\end{subfigure}
\caption{\label{tab:org5683d81}Example of \emph{content} and \emph{style} decomposition.}
\centering
\end{figure}

The same also happens for the example snippet in the readme. Unfortunately I have not been able to figure out a solution myself.

I get this error when installing:

(error "Package lacks a file header")

Issue is fixed here:

@conao3 ?

Sorry if i am doing something stupid.
I loaded ox-latex-subfigure and created a little table analog to the README:

#+NAME: fig:nogora
#+CAPTION: Blablabla
#+ATTR_LATEX: :environment subfigure :width 0.4\textwidth :align c
| file:../nogora/ecalhisto.pdf | file:../nogora/ecalhisto-cut.pdf |

When exporting (i.e. C-e l l) I get the error message "wrong-type-argument integer-or-marker-p nil".

It seems to refer to the call to text-properties-at in line 12. of the .el file, with pt being nil.

Below is the backtrace:

When exporting normal figures I can insert a shortcaption for the table of figures (whole caption looks pretty bad there.
With subfigure this does not work. When inserting #+caption[short]long then neither gets exported.
I tried with

+ATTR_LATEX: :caption \caption[short]long

and also no luck...

Minimal example:

+CAPTION[This short caption exports well]: Longcaption

+LABEL: fig:figure

figure 1

+CAPTION[Short caption]: Long caption that is so long that it does not fit or look good in the table of figures, needing a short caption for that...

+LABEL: fig:subfigure_example1

+ATTR_LATEX: :environment subfigure :width 0.49\linewidth :align b

| This is a subcation of the first image | This is a subcaption of the second image. |
| figure 1 | figure 2 |

I think it would be nice if it were possible to add a default subfigure options using something like like:

#+BIND: org-subfigure-default-option "height=2cm"

Then, if the third row of a table is not set:

#+name: fig:force_deflection_characteristics
#+caption: Force-deflection characteristics
#+attr_latex: :environment subfigure :width 0.32\linewidth :align t
| file:dry_friction.png             | file:viscous_damper.png               |
| <<fig:dry_friction>> Dry friction | <<fig:viscous_damper>> Viscous damper |

It would produce:

\begin{figure}[htbp]
\centering
\begin{subfigure}[t]{0.32\linewidth}\centering
\includegraphics[height=2cm]{dry_friction.png}
\caption{\label{fig:dry_friction} Dry friction}
\end{subfigure}
\begin{subfigure}[t]{0.32\linewidth}\centering
\includegraphics[height=2cm]{viscous_damper.png}
\caption{\label{fig:viscous_damper} Viscous damper}
\end{subfigure}
\caption{\label{fig:force_deflection_characteristics}
Force-deflection characteristics}
\end{figure}

Thanks :)

Hi,
First of all, thank you for this package, very useful! :)

I would like to be able to tune the size of the subfigures, ideally individually, but at least setting one default size.

For now, it seems it takes the default width defined by =org-latex-image-default-option= or =org-latex-image-default-width=.

Can I tune that for subfigures? Like having one variable =org-latex-subfigure-width=?

Thanks

In my org-mode setup I need to have the option "Org Latex Tables Centered" disabled, because of issues when using threeparttable and sidewaystable (see link)
https://www.mail-archive.com/[email protected]/msg104079.html

To still center all float environments I inserted:

+LATEX_HEADER: \makeatletter

+LATEX_HEADER: \g@addto@macro@floatboxreset\centering

+LATEX_HEADER: \makeatother

But this does not work with ox-latex-subfigure, and :align option only allows for t,c,b
Is there some possibility to get \centering on export with "Org Latex Tables Centered" disabled?
Or could you indicate what to change in your code to get that behaviour (I see \centering at various points, but do not know where to change it). In my use case I would always center align, so no need for any conditional....

Only the captions were updated but no figures were exported. So I updated today.
Now I only get the error message:

if: Search failed: "\\\\
?"

Hello. Thank you very much for your package.
I want to let you know that it is currently braking my table.el for some reasons. I commented the sections of my .emacs where ox-latex-subfigure is, and table.el is working again. I get a wrong-type-argument integer-or-marker-p nil . I checked the issues in the repo, and I don't think that it's the same as #6

I'm attaching my configuration for org-mode.

Hi!
I like this package. Do you have an idea to add this package to MELPA?
Registering with MELPA allows more Emacs users to use this package.

If you think it is troublesome, I will Fork and register. If you don't like having too many repositories, you can help with ongoing maintenance by making me a collaborator.

Best,

Hello,

I tried ox-latex-subfigure today. I loaded it with the code you provided and tried your minimal example,
changing path of both of course. It still exports to table...
What am I doing wrong?
\begin{table}[!htbp]
\caption{\label{fig:hello}
Use figure/subfigure instead of tabular, remember to set \texttt{:environment}}
\begin{subfigure}{0.4\textwidth}{c}
\includegraphics{/home/mcg/picture1.jpg} & \includegraphics{/home/mcg/picture2.jpg}
tttttt & zzzzzz
\end{subfigure}
\end{table}
\end{document}

Hi,
I just updated to last version, and I have a problem of additional \end{subfigure} added as shown in the below generated latex code.

\begin{figure}[htbp]
\centering
\begin{subfigure}[b]{0.3\linewidth}\centering
\includegraphics[\end{subfigure}
]{nyquist_point.png}
\caption{\label{fig:nyquist_point} Point receptance}
\end{subfigure}
\begin{subfigure}[b]{0.3\linewidth}\centering
\includegraphics[]{nyquist_transfer.png}
\caption{\label{fig:nyquist_transfer} Transfer receptance}
\end{subfigure}
\caption{\label{fig:nyquist_frf_plots}
Nyquist FRF plot for proportionally-damped system}
\end{figure}

I had not this problem previously.

Thanks :)
