我尝试减少标题文本（而不是自动标签“图片”）并将其与回忆录更好地对齐。我尝试这样做这没有成功，我在回忆录文档中搜索，并尝试了一些命令，但也没有成功。
我的示例代码：
\documentclass[a4paper, 12pt,twoside, openright]{memoir}
\usepackage{polyglossia}
\setdefaultlanguage{french}
\usepackage{fontspec}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage[autostyle=true,french=guillemets,maxlevel=3]{csquotes}
\usepackage{xparse}
\usepackage{graphicx}
\usepackage[protrusion=true]{microtype}
\graphicspath{{FigureIntroduction/}}
\tolerance=1000
\sidecapmargin{outer}
\setsidecappos{t}
\makeatletter
%\renewcommand{\fnum@figure}[1]{\textbf{\figurename~\thefigure}}
\renewcommand{\fnum@figure}{\textbf{Figure~\thefigure~--}}
\makeatother
\captiondelim{\newline}
\captionstyle{\centerlastline}% for title
\setlength{\belowcaptionskip}{\onelineskip}
\setlength{\footnotesep}{\onelineskip}
\captionnamefont{\small}
\captiontitlefont{\small}
\begin{document}
\chapterstyle{bringhurst}
\begin{figure}[!h]

%\resizebox*{\textwidth}{!}{\includegraphics{champignonKaplan.png}}
\includegraphics[width=\linewidth]{champignonKaplan.png}
\end{sidecaption}
\end{figure}

结果如下：
答案1
您正在查看的宏是\sidecapstyle（在章节10.10.1 调整，文档第 199 页memoir）具有默认定义：
\newcommand*{\sidecapstyle}{%
%%% \captionnamefont{\bfseries}%
\ifscapmargleft
\captionstyle{\raggedleft}%
\else
\captionstyle{\raggedright}%
\fi}
您可以在那里介绍您的修改：
\renewcommand*{\sidecapstyle}{%
\ifscapmargleft
\captionstyle{\justifying\scriptsize}%
\else
\captionstyle{\justifying\scriptsize}%
\fi}
（\justifying需要ragged2e包）。完整的示例：
\documentclass[a4paper, 12pt,twoside, openright]{memoir}
\usepackage{polyglossia}
\setdefaultlanguage{french}
\usepackage{fontspec}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage[autostyle=true,french=guillemets,maxlevel=3]{csquotes}
\usepackage{xparse}
\usepackage{graphicx}
\usepackage[protrusion=true]{microtype}
\usepackage{ragged2e}
\usepackage{lipsum}
\sidecapmargin{outer}
\setsidecappos{t}
\makeatletter
\renewcommand{\fnum@figure}{\textbf{Figure~\thefigure~--}}
\makeatother
\captiondelim{\newline}
\renewcommand*{\sidecapstyle}{%
\ifscapmargleft
\captionstyle{\justifying\scriptsize}%
\else
\captionstyle{\justifying\scriptsize}%
\fi}
\begin{document}
\chapterstyle{bringhurst}
\begin{figure}[!ht]
\begin{sidecaption}[fortoc]{Le "champignon informationnel" proposé par Frédéric Kaplan est révélateur de l'augmentation du champs d'expérimentation rendu possible par la numérisation des données, puis la simulation numérique.}[fig:I_Champi]
\includegraphics[width=\linewidth,height=5cm]{example-image-a}
\end{sidecaption}
\end{figure}
\lipsum[4]
\end{document}
但是请注意，现在您可能会得到（如示例代码所示）某些行中的间距不好的结果，因为为标题保留的空间太窄了。也许您应该重新考虑关于对齐的决定。
