LaTeX 图像添加边框 - 如何使用 \fbox 命令

\begin{figure}\centering\begin{minipage}[c]{0.48\textwidth}\centering\fbox{\includegraphics[height=0.2\textheight]{总.png}}\subcaption{}\end{minipage}\begin{minipage}[c]{0.48\textwidth}\centering\fbox{\includegraphics[height=0.2\textheight]{总 (2).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (3).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (4).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (5).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (6).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (7).png}}\subcaption{}\end{minipage}\caption{恢复后（b）分割前（a）的文档}\end{figure} 要为图片添加边框，可以使用\fbox命令将图片包裹在一个框中。修改代码如下： \begin{figure}\centering\begin{minipage}[c]{0.48\textwidth}\centering\fbox{\includegraphics[height=0.2\textheight]{总.png}}\subcaption{}\end{minipage}\begin{minipage}[c]{0.48\textwidth}\centering\fbox{\includegraphics[height=0.2\textheight]{总 (2).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (3).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (4).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (5).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (6).png}}\fbox{\includegraphics[height=0.2\textheight]{总 (7).png}}\subcaption{}\end{minipage}\caption{恢复后（b）分割前（a）的文档}\end{figure} 这样，每个图片都会被一个带有边框的框包围起来。
