在同一页面中对齐多个图像

Question

我还剩下 3/4 的页面空间来对齐 4 张图片。页面空间有限，我想让它们全部都合适。

\documentclass{article}
\usepackage{graphicx} % Required for inserting images

\title{sample}

\begin{document}

\maketitle

\begin{frame}{}
\begin{figure}[ht]
    \begin{minipage}[b]{0.45\linewidth}
        \centering
        \includegraphics[scale=0.45]{Figures/edaaml1.jpg}
        \caption{AMLSim: All transactions in each timestep}
        \label{fig:16}
    \end{minipage}
    \hspace{0.5cm}
    \begin{minipage}[b]{0.45\linewidth}
        \centering
        \includegraphics[scale=0.45]{Figures/edaaml2.jpg}
        \caption{AMLSim: SAR transactions in each timestep}
        \label{fig:17}
    \end{minipage}
    \begin{minipage}[b]{0.45\linewidth}
        \centering
        \includegraphics[scale=0.32]{Figures/edaellip.jpg}
        \caption{Elliptic: All transactions in each timestep}
        \label{fig:18}
    \end{minipage}
    \hspace{0.5cm}
    \begin{minipage}[b]{0.45\linewidth}
        \centering
        \includegraphics[scale=0.35]{Figures/edaellip2.jpg}
        \caption{Elliptic: Illicit transaction graph in timestep 41}
        \label{fig:19}
    \end{minipage}
\end{figure}
\end{frame}

\end{document}

目前看起来是这样的：

问题是图像太小（试图将其放在一页中）并且标题太拥挤。可以减少边距以容纳它们，但我只能更改此页面的边距吗（我不想破坏文档其余部分的对齐方式），或者是否有图像网格可以让我适当地调整这些数字？

我猜，你正在经历这样的事情：

对于上图，我们使用了framed包。框架在浮动内消失figure：

\documentclass{article}
\usepackage{graphicx} % Required for inserting images
\usepackage{framed}   % for frame around images

\begin{figure}[ht]
\setkeys{Gin}{width=\linewidth}
\begin{framed}  % <--
    \begin{minipage}[b]{0.45\linewidth}
        \includegraphics{example-image-duck}% {Figures/edaaml1.jpg}
        \caption{AMLSim: All transactions in each timestep}
        \label{fig:16}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.45\linewidth}
        \includegraphics{example-image-duck}% {Figures/edaaml2.jpg}
        \caption{AMLSim: SAR transactions in each timestep}
        \label{fig:17}
    \end{minipage}\\

\medskip  
    \begin{minipage}[b]{0.45\linewidth}
        \includegraphics{example-image-duck}% {Figures/edaellip.jpg}
        \caption{Elliptic: All transactions in each timestep}
        \label{fig:18}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.45\linewidth}
        \includegraphics{example-image-duck}% {Figures/edaellip2.jpg}
        \caption{Elliptic: Illicit transaction graph in timestep 41}
        \label{fig:19}
    \end{minipage}
\end{framed}
    \end{figure}

在这种情况下，图形突出外边框的量为\marginparwidth+\marginparsep：

\documentclass{article}
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%
\usepackage{lipsum}% For dummy text. Don't use in a real document
