将自动文本添加到图号

将自动文本添加到图号

我想根据（自动）参考编号向图号添加一些自动文本。

一个最小的例子。

\documentclass{article}

\begin{document}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is figure 1}
\label{fig1}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 2}
    \label{fig2}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 3}
    \label{fig3}
\end{figure}

i want to get "figure (1)'de" when i write " figure (\ref{fig1})",\\
i want to get "figure (2)'se" when i write "figure (\ref{fig2})",\\
i want to get "figure (3)'te" when i write "figure (\ref{fig3})" 

\end{document}

答案1

据我理解，图号后应出现后缀de或se。我已定义一个宏，可自动添加这些后缀，假设图号大于或等于 3 时仍应保留后缀。作为额外奖励，该宏会自动将单词“图”添加到参考资料中。te\frefte

输出如下：

在此处输入图片描述

代码如下：

\documentclass{article}
\usepackage{refcount}
\newcommand\fref[1]{%
  Figure~(\getrefnumber{#1})`\ifcase\getrefnumber{#1}\or de\or se\else te\fi}

\begin{document}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is figure 1}
\label{fig1}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 2}
    \label{fig2}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 3}
    \label{fig3}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 4}
    \label{fig4}
\end{figure}

Reference for fig1: \fref{fig1}.

Reference for fig2: \fref{fig2}.

Reference for fig3: \fref{fig3}.

Reference for fig4: \fref{fig4}.

\end{document}

需要注意的是，这适用于您的 MWE，但如果图形编号包含章节或节号，例如看起来像 3.4，那么就需要进行修改。

编辑

正如已经强调的那样，如果图号包含节号或章节号，则上述解决方案将不起作用。以下贡萨洛·梅迪纳，以下是处理这种情况的一种方法：

\documentclass{amsart}
\numberwithin{figure}{section}

\usepackage{refcount}
\usepackage{xstring}
\newcommand\fref[1]{\IfRefUndefinedExpandable{#1}{??}{Figure~(\ref{#1})`\addrefending{#1}}}
\newcommand\addrefending[1]{\StrBehind{\getrefnumber{#1}}{.}[\fignumber]%
  \ifcase\fignumber\relax\or de\or se\else te\fi}

\begin{document}

\section{Section with figures}
\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is figure 1}
\label{fig1}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 2}
    \label{fig2}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 3}
    \label{fig3}
\end{figure}

\begin{figure}
    \centering
    \rule{1cm}{1cm}
    \caption{This is figure 4}
    \label{fig4}
\end{figure}

Reference for fig1: \fref{fig1}.

Reference for fig2: \fref{fig2}.

Reference for fig3: \fref{fig3}.

Reference for fig4: \fref{fig4}.

\end{document}
