等尺寸子图

Question

我希望我的子图看起来统一，因此每个子图都具有相同的宽度和高度。此外，两行中的每一行都应该有一个中心，该行中的所有子图都围绕该中心居中。

我希望这能够自动发生，而无需摆弄高度、宽度和比例参数，直到一切都适合。

我的代码：

\documentclass{article}
\usepackage[abs]{overpic}
\usepackage{graphicx}
\usepackage{subfig}
\usepackage{siunitx}
\begin{document}

\iffalse
\begin{overpic}[grid,tics=10,width=\textwidth]{pictures/reflectors/whiteboard-back/frontal.jpg}
\end{overpic}
\vskip 1cm
\begin{overpic}[grid,tics=10,trim=20 10 20 0,width=\textwidth]{pictures/reflectors/whiteboard-back/frontal.jpg}
\end{overpic}
\vskip 1cm
\begin{overpic}[grid,tics=10,trim=20 10 20 0,clip,width=\textwidth]{pictures/reflectors/whiteboard-back/frontal.jpg}
\end{overpic}
\fi

\subfloat[\SI{30}{\degree} left]{\includegraphics[height=0.4\textwidth]{results/rp/glassdoor-aac-30deg_left_rp.pdf}} \qquad
\subfloat[\SI{30}{\degree} right]{\includegraphics[height=0.4\textwidth]{results/rp/glassdoor-aac-30deg_right_rp.pdf}} \qquad

\subfloat[\SI{60}{\degree} right]{\includegraphics[height=0.4\textwidth]{results/rp/glassdoor-aac-60deg_right_rp.pdf}} \qquad
\subfloat[\SI{90}{\degree}]{\includegraphics[height=0.4\textwidth]{results/rp/glass-door-90deg_rp.pdf}} \qquad
\subfloat[Measurement location]{\includegraphics[angle=-90,origin=c,height=0.4\textwidth]{pictures/reflectors/glassdoor/frontal.jpg}} \qquad

Answer 1

这是我建议的答案（尽管有点冗长）。

• 定心：它使用\minipages（因为您已经知道它将有 3 行 2 列） + \hfill，并\adjustbox使用 esvalign=t,center选项将最后一个居中。
• 足够大小我们使用根据给定的宽度和高度，将包含的图形缩放到更高的比例，而不是更低的比例：使用keepaspectratio选项\includegraphics，结合定义（最大）width和height（根据（a）与（e）图片的比例：我在这里假设它们是 3/4 -- 因此width = 0.75\textwidth）

Answer 2

这是一个更简单的解决方案。我使用 \tempheight 来均衡高度，使用 \raisebox 来对齐底部。唯一需要调整的是适合页面。

\documentclass{article}
    \usepackage{graphicx}
    \usepackage{siunitx}
    \usepackage{showframe}% check centering
    \newlength{\tempheight}
\begin{document}

\begin{figure}
  \settoheight{\tempheight}{\includegraphics[width=0.4\textwidth]{example-image-a}}
  \hfil\begin{tabular}{cc}
      \includegraphics[width=0.4\textwidth]{example-image-a} &
        \includegraphics[width=0.4\textwidth]{example-image-a} \\
      \SI{30}{\degree} left & \SI{30}{\degree} right \\[1ex]
      \includegraphics[width=0.4\textwidth]{example-image-a} &
        \includegraphics[width=0.4\textwidth]{example-image-a} \\
      \SI{60}{\degree} left & \SI{60}{\degree} right \\[1ex]
      \includegraphics[width=0.4\textwidth]{example-image-a} &
        \raisebox{\depth}{\includegraphics[width=\tempheight, angle=-90]{example-image-b}} \\
      \SI{90}{\degree} & Measurement location
  \end{tabular}
\caption{Range measurements for clear glass at 30,60,90 degree angles of incidence from the left and the right side}
\label{fig:rp_glassdoor}
\end{figure}
