Me gustaría poner el texto con derechos de autor de una imagen actualmente en la Lista de Figuras, pero tal vez tenga que cambiarlo y colocarlo (también) debajo de cada imagen.
Este MWE funciona bien:
\documentclass{article}
\usepackage{graphicx}
\usepackage{caption}
\newcommand\after[1]{#1}
\newcommand\afterlof{; \after}
\newcommand\aftercap{ }%for optional use
\begin{document}
\begin{figure}[htb]
\includegraphics[width=.5\textwidth]{example-image-a}
\def\after{the copyright for this image}
\caption%
[caption for LOF\afterlof]%
{caption below the image\aftercap}
\end{figure}
\begin{figure}[htb]
\includegraphics[width=.5\textwidth]{example-image-a}
\def\after{the copyright for another image}
\caption%
[caption for LOF\afterlof]%
{caption below the image\aftercap}
\end{figure}
\listoffigures
\end{document}
Mi pregunta:
Hay alguna manerano¿poner los dos comandos (
afterlof
yaftercap
) en cada título manualmente? ¿De modo que, por definición, el título siempre se verá así\caption[ \afterlof]{ \aftercap}
?

Propongo una interfaz clave-valor:

\usepackage{xparse}
\ExplSyntaxOn

\lukascb_make_caption:VVVV
\l_lukascb_caption_text_tl
\l_lukascb_caption_aftercap_tl
\l_lukascb_caption_loftext_tl
\l_lukascb_caption_afterlof_tl

Si no especifica loftext
, se utiliza el texto del título principal. El valor de afterlof
se añade a la lista de figuras, el valor de aftercap
al título principal.
Por lo tanto, sólo tienes que agregar las claves si quieres usarlas.
Una extensión para \subcaptionbox
, la sintaxis es similar: el primer argumento opcional \subcaptionbox
se convierte en una lista de opciones.

Un 'truco' rápido mediante una redefinición de \caption
with xparse
's \NewDocumentCommand
y probando si \after
etc. está definido.
Use \def\after{...}
o \newcommand{\after}
dentro del entorno de la figura, como tal, que el comando no esté definido afuera y la prueba hará la false
rama, no imprima texto adicional.
