![指向 \thefigure 的超目标](https://linux22.com/image/323282/%E6%8C%87%E5%90%91%20%5Cthefigure%20%E7%9A%84%E8%B6%85%E7%9B%AE%E6%A0%87.png)
希望这是我问的最后一个问题,关于扩展图形标题宏。在上一个版本中这里,hyperref
不影响\addefcline
或\efcline
,每次使用该函数时,我都必须在图形上定义一个超目标\extcaption
。
简而言之,我如何才能创建一个指向的超目标,\thefigure
以使该过程自动化?此外,是否有某种ifhyperref
包(用于检查 hyperref 是否已加载)?
这是 MWE

\begin{figure}

\extcaption{\lipsum[1-2]}
\end{figure}
\begin{figure}
\includegraphics{example-image-b.pdf}
\caption{Picture of a big B}\hypertarget{fig:\thefigure}{}
\extcaption{The reasons why B is awful
\begin{itemize}
\item "B" like Bad
\item "B" like Banana

}

\section{Extended figure captions}
\printextcaptions

答案1
hyperref
使用的变量找到了解决方案。这\@currentHref
给出了最终的代码:
% Redefinition of \addcontentsline
\long\def\addefcline#1#2#3{%
\addtocontents{#1}{\efcline{#2}{#3}{\thepage}}}
% Redefinition of \contentsline
\makeatletter
\long\def\efcline#1{\csname l@#1\endcsname}
% Extended figure caption
\AtBeginDocument{\@ifpackageloaded{hyperref}{ % If hyperref loaded
\newcommand{\extcaption}[1]{% Write to .efc file
\addefcline{efc}{extfig}{{%
\bfseries \protect\hyperlink{\@currentHref}{Figure \thefigure, page~\thepage:}} %
\unexpanded{\unexpanded{#1}}}}}{% If hyperref not loaded
\newcommand{\extcaption}[1]{% Write to .efc file
\addefcline{efc}{extfig}{{%
\bfseries Figure \thefigure, page~\thepage:} %
\unexpanded{\unexpanded{#1}}%
}}}}
% Read .efc file
\newcommand{\printextcaptions}{\@starttoc{efc}}
\newcommand{\l@extfig}[2]{\noindent #1 \vspace{\parskip} \par}% How each .efc entry is handled
\makeatother
回顾一下,在浮动图形中添加了一个扩展的图形标题,如下所示
\begin{figure}
\includegraphics{example-image-a.pdf}
\caption{Picture of a big A}
\extcaption{\lipsum[1-2]}
\end{figure}
,生成一个.efc
包含所有内容的文件\extcaption{}
,由 打印
\printextcaptions
