减少用户定义环境中的行距

Question

我的文档中有很多图表和表格，我创建了两个命令\source和\notes来格式化图表/表格的源并添加任何注释（请参阅 MWE）。正文有双倍行距，如何在我新定义的环境中将行距减少到一半或单倍行距\notes？

\documentclass[a4paper, 12pt]{report}

\usepackage[english,frenchb]{babel}
\usepackage{graphicx}
\usepackage{adjustbox}
\usepackage{subcaption}

\linespread{1.6} %Setting double spacing for document

%---- Create 'source' and 'notes' commands ----%
\newcommand{\source}[1]{\vspace{-1.5em}
\captionsetup{justification=justified} \caption*{\raggedright\textnormal{\footnotesize{\textit{#1}}}}}

\newcommand{\notes}[1]{\vspace{-0.5em} 
% Would like 1.5 spacing for 'notes' environment
\captionsetup{justification=justified} \caption*{\textnormal{\scriptsize{\textit{#1}}}}}

\linespread{1.6}

\begin{document}

\begin{figure}[h!]
\begin{center}
\caption{A figure}
\resizebox{!}{70mm}{\includegraphics{{example-image-a}}}
\end{center}
      \source{Source : source of figure.}
      \notes{Notes : Some very long notes spread over several lines of which I would like to reduce linespacing. Some very long notes spread over several lines of which I would like to reduce linespacing. Some very long notes spread over several lines of which I would like to reduce linespacing. Some very long notes spread over several lines of which I would like to reduce linespacing.}
\end{figure}

Answer 1

只需将\linespread{0.0}（单倍行距，或任何其他您喜欢的数字）添加到\notes宏的定义中即可。

\documentclass{report}
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{lipsum}

\linespread{1.6}

\newcommand{\source}[1]{%
    \vspace{-1.5em}%
    \captionsetup{justification=justified}%
    \caption*{\raggedright\footnotesize\textit{#1}}%
}

\newcommand{\notes}[1]{%
    \linespread{0.0}\vspace{-0.5em}%
    \captionsetup{justification=justified}%
    \caption*{\scriptsize\textit{#1}}%
}

\begin{document}

\begin{figure}[h!]
    \begin{center}
        \caption{A figure}
        \includegraphics[height=70mm]{example-image-a}
    \end{center}
    \source{Source : source of figure.}
    \notes{Notes : \lipsum[1]}
\end{figure}

\lipsum[2]

\end{document}

Answer 2

将格式说明添加到\captionsetup并使用setspace。请注意\linespread{1.6}本质上与 相同\doublespacing。

\documentclass[a4paper, 12pt]{report}

\usepackage[english,frenchb]{babel}
\usepackage{graphicx}
\usepackage{adjustbox}
\usepackage{subcaption}
\usepackage{setspace}

\doublespacing

%---- Create 'source' and 'notes' commands ----%
\newcommand{\source}[1]{%
 \begingroup
 \captionsetup{justification=raggedright,font={footnotesize,it,onehalfspacing}}%
 \caption*{#1}%
 \endgroup
}

\newcommand{\notes}[1]{%
  \begingroup
  \captionsetup{justification=justified,font={scriptsize,it,onehalfspacing}}%
  \caption*{#1}%
  \endgroup
}

\begin{document}

\begin{figure}[htp!]
\centering
\caption{A figure}
\includegraphics[width=70mm]{example-image-a}

\source{Source : source of figure.}
\notes{Notes : Some very long notes spread over several lines of which 
  I would like to reduce linespacing. Some very long notes spread over
  several lines of which I would like to reduce linespacing. Some very
  long notes spread over several lines of which I would like to reduce
  linespacing. Some very long notes spread over several lines of which
  I would like to reduce linespacing.}
\end{figure}
