使侧边图适合页面宽度，包括标题和来源

Question

我正在尝试在文档中添加侧向图形，但是当我将宽度设置为时，\textwidth它显得太宽了。

这是我的代码：

\usepackage{rotating}

\begin{sidewaysfigure}
   \centering
   \begin{minipage}{\textwidth}
      \caption{The caption}
      \includegraphics[width=\textwidth]{img/diagramm_hs.png}\\
      \source{The source}
      \label{fig:diagramm_hs}
   \end{minipage}
\end{sidewaysfigure}

结果如下：

如您所见，图像比文本宽度宽（textwidth与标题中的行一样宽），尤其是标题和来源。

如何才能使页面上的图像尽可能大，同时让所有内容（包括标题和来源）保留在文本区域中？

编辑：图像尺寸为 1327x960 像素。这是我的文档类：

\documentclass[
paper=A4,
fontsize=12pt,
BCOR12mm,
DIV14,
parskip=half*,
headsepline,
listof=totoc,
footinclude=false,
headinclude=true,
final
]{scrartcl}

Answer 1

\textwidth首先，使用 会丢失原始数据sidewaysfigure。其次，我需要测试总数字是否太大。最后，我需要使用 来计算图像高度，[width=\textwidth]以确定[height=]应该用 来补偿什么。

我进行了测试\listoffigures以确保仅出现一个标题。

\documentclass{article}
\usepackage{showframe}
\usepackage[Export]{adjustbox}
\usepackage{rotating}
\usepackage{caption}
\captionsetup{justification=raggedright,
               singlelinecheck=false}

\newcommand{\source}[1]{\ttfamily #1}

\newsavebox{\tempbox}
\newlength{\tempdima}
\newlength{\tempdimb}
\newlength{\tempdimc}

\begin{document}
  \tempdima=\textwidth% inside \textwidth=\linewidth=\textheight
  \begin{sidewaysfigure}
  \textheight=\tempdima
  \settoheight{\tempdimb}{\includegraphics[width=\textwidth]{example-image-a}}% default height
  \savebox{\tempbox}{\begin{minipage}{\textwidth}
    \caption{The caption}
    \addtocounter{figure}{-1}% reset
    \rule{\textwidth}{\tempdimb}% same size but faster
    \par\source{The source}
    \end{minipage}}%
  \tempdima=\ht\tempbox\relax% can't get \dimexpr to work
  \advance\tempdima by \dp\tempbox\relax
  \tempdimc=\tempdimb
  \ifdim\textheight<\tempdima
    \advance\tempdimb by \textheight
    \advance\tempdimb by -\tempdima
  \fi
  \tempdima=\dimexpr \tempdimb*\textwidth/\tempdimc\relax% compute scaled width
  \hfil\begin{minipage}{\tempdima}
  \caption{The caption}
  \includegraphics[width=\textwidth]{example-image-a}\par
  \source{The source}
  \end{minipage}
  \end{sidewaysfigure}
\end{document}

Answer 2

据我所知，您尚未提供任何有关图像自然大小（或其自然高宽比）、文本块尺寸甚至您使用的文档类别的信息。因此无法提供非常具体的建议。

我能想到的建议就是将图像的宽度设置为\textwidth，高度设置为0.7\textheight；见下面的屏幕截图。根据图像的自然尺寸，您可能需要调整系数0.7；设置选项 也可能会很有用keepaspectratio。

\documentclass{report}
\usepackage{caption}
\captionsetup{justification=raggedright,
               singlelinecheck=false}
\usepackage{rotating}
\usepackage[showframe]{geometry}
\begin{document}    

\begin{sidewaysfigure}
   \caption{The caption}
   \label{fig:diagramm_hs}
   \includegraphics[width=\textwidth,
                    height=0.7\textheight,
                    %keepaspectratio  % may need to uncomment this option
                   ]{example-image-a}
