在每个图形（包括标题）的上方和下方添加一条规则

Question

我有一份包含大量图片的文档，我想修改它们，以便每个图片的上方和下方都有一条水平线，使其与文本区分开来。也就是说，我希望它看起来像这样：

文本.... 文本.... 文本....

文本.... 文本.... 文本....

- - - - - - - - - - - - - - - - ％ 规则

点击此处

...........

图片标题：blah blah

------------------------------- %另一条规则

文本.... 文本.... 文本....

我知道我可以单独去修改每个图形，但我想知道是否有办法自动对所有图形执行此操作......

您可以使用float。

\documentclass{article}
\usepackage{graphicx}
\usepackage{float}

\makeatletter
\newcommand\fs@tbruled{%
  \def\@fs@cfont{\normalfont}%
  \let\@fs@capt\floatc@plain
  \def\@fs@pre{\hrule\kern2pt}%
  \def\@fs@post{\kern2pt\hrule\relax}%
  \def\@fs@mid{\vspace{\abovecaptionskip}}%
  \let\@fs@iftopcapt\iffalse
}
\makeatother

\floatstyle{tbruled}
\restylefloat{figure}

\begin{document}

Some text before your figure. Some text before your figure. Some text before your figure. 
Some text before your figure.
\begin{figure}[htp]
\centering

\includegraphics{example-image-a}
\caption{My caption}

\end{figure}
Some text after your figure. Some text after your figure. Some text after your figure. 
Some text after your figure.

\end{document}

让我们看看这些命令的作用：

\def\@fs@cfont{\normalfont}%              The font for the caption label
\let\@fs@capt\floatc@plain %              Use plain style caption
\def\@fs@pre{\hrule\kern2pt}%             The rule at the top
\def\@fs@post{\kern2pt\hrule\relax}%      The rule at the bottom
\def\@fs@mid{\vspace{\abovecaptionskip}}% Material to be inserted before the caption
\let\@fs@iftopcapt\iffalse %              We don't want the caption is moved at the top

如果你想要在顶部规则之后有更多空间，请更改为

\def\@fs@pre{\hrule\kern12pt}%

或任何你认为合适的空间。底部的规则也类似。

只需创建您自己的环境。

\documentclass{article}
\usepackage{graphicx}
\newenvironment{myfigure}%
    {\begin{figure}[htb]\hrule\vspace{3ex}\centering}%
    {\vspace{3ex}\hrule\end{figure}}

\begin{document}
Some text before your figure. Some text before your figure. Some text before your figure. Some text before your figure.%
\begin{myfigure}
    \includegraphics{example-image-a}
    \caption{My caption}
\end{myfigure}
Some text after your figure. Some text after your figure. Some text after your figure. Some text after your figure.
\end{document}
