如何缩进 captionof 内的文本？

Question

有人知道如何缩进 captionof 中的文本吗？我有一个很长的标题，我想将其分成两段，但缩进似乎不起作用。

\documentclass{article}

\usepackage{caption}
\usepackage[demo]{graphicx}

% make demo figure
\makeatletter
  \AtBeginDocument{%
    \def\Ginclude@graphics#1{%
      \begingroup\fboxsep=-\fboxrule
      \fbox{\rule{\@ifundefined{Gin@@ewidth}{150pt}{\Gin@@ewidth}}{0pt}%
        \rule{0pt}{\@ifundefined{Gin@@eheight}{100pt}{\Gin@@eheight}}}\endgroup}}
\makeatother

\begin{document}

\noindent
\begin{minipage}[c]{\linewidth}
\centering
\includegraphics{}
\captionof{figure}{\textbf{Title} \newline
\indent Paragraph 1 is found here with a lot of text lot of text lot of text lot of text lot of text lot of text \newline
\indent Paragraph 2 is found here with a lot of text lot of text lot of text lot of text lot of text lot of text}
\label{fig:angio}
\end{minipage}

\end{document}

Answer 1

这是因为两个原因。首先， 会使minipage的值无效\parindent。其次，标题通常也以避免缩进的方式设置。您可以保存当前\parindent并手动强制对齐：

\documentclass{article}

\usepackage{caption}
\usepackage{graphicx}

\newlength{\savedparindent}
% Save \parindent
\AtBeginDocument{\setlength{\savedparindent}{\parindent}}

\begin{document}

\noindent
\begin{minipage}{\linewidth}
  \centering
  \includegraphics[width=.5\linewidth]{example-image}
  \captionof{figure}[Title]{\textbf{Title} \newline
  \hspace*{\savedparindent}Paragraph 1 is found here with a lot of text lot of text lot of text lot of text lot of text lot of text \newline
  \hspace*{\savedparindent}Paragraph 2 is found here with a lot of text lot of text lot of text lot of text lot of text lot of text}
\end{minipage}

\end{document}

您可以使用以下功能caption使用选项 自行存储[parindent=\parindent]。但是，这要求您将每个段落指定为段落- 在它们之间留一行空行：

  \captionof{figure}[Title]{\textbf{Title}

  Paragraph 1 is found here with a lot of text lot of text lot of text lot of text lot of text lot of text

  Paragraph 2 is found here with a lot of text lot of text lot of text lot of text lot of text lot of text}

请注意，我使用了可选标题Title来避免 LoF 中的内容复杂化。

Answer 2

我不会使用\newline(不开始新段落) 但\par(或空白行) 来获取真正的段落。然后我会设置\captionsetup{parindent=\parindent}并删除\indent。需要在可选参数中指定一个较短的版本，而没有段落分隔符，以避免错误：

\documentclass{article}

\usepackage{caption}
\captionsetup{parindent=\parindent}
\usepackage[demo]{graphicx}

\begin{document}

\begin{center}
  \includegraphics{foo}
  \captionof{figure}[\textbf{Title}: shorter version]{\textbf{Title}\par
    Paragraph 1 is found here with a lot of text lot of text lot of text lot
    of text lot of text lot of text \par
    Paragraph 2 is found here with a lot of text lot of text lot of text lot of
    text lot of text lot of text.}
\label{fig:angio}
\end{center}
