如何减少特定图形的 \subcaption 中的标题字体

如何减少特定图形的 \subcaption 中的标题字体

如何缩小\subfigureBeamer 环境中特定图形的字体大小。我知道如何缩小标题字体全球 \usepackage[font=small]{subcaption}，但我正在寻找字体大小处理本地。

\subfigure我使用from包在一个框架中显示四个子图\subcaption。问题是子图的各个标题，（A B C D），与子图片中使用的标签文本相比，它们太大了。因此，如果我增加单个子图的高度，\begin{subfigure}{.49\textwidth}那么这四张图片就会超出页面，如果我减小它的大小，那么与标题相比，图中使用的字体就会太小。因此，我想减小标题字体，这样图片中使用的文本看起来就不会太糟糕。

答案1

我会添加说明

\captionsetup[subfigure]{font=scriptsize,labelfont=scriptsize}

之后\begin{figure}。这样，设置更改就只针对这个特定figure环境。

        \label{fig7a}
    \end{subfigure} \hspace*{\fill}
    \begin{subfigure}{.49\textwidth}

    \begin{subfigure}{.49\textwidth}

    \end{subfigure}
    \caption{\textbf{My caption}}
    \label{f7}
\end{figure}
\end{frame}

\end{document}

附录：如果您想要让整个图形标题显示在框架中，则必须减小图像的尺寸，可能类似于下面的示例。

随后重新定义\thesubfigure并恢复正常字体大小即可得到所需的结果：

\documentclass{beamer}

\usetheme{Warsaw}
\useoutertheme{infolines}

\usepackage{caption}
\usepackage[labelformat=simple]{subcaption}

\setbeamertemplate{caption}[numbered] 

\captionsetup{font=bf}

\renewcommand\thesubfigure{\normalfont(\alph{subfigure})}

\begin{document}

    \begin{frame}
        \begin{figure}[h!]
            \begin{subfigure}{.49\textwidth}
                \renewcommand\thesubfigure{\fontsize{5}{8}\selectfont (\alph{subfigure})}
                \includegraphics[width=1\linewidth]{pic}
                \caption{ }
                \label{fig7a}
                \renewcommand\thesubfigure{\normalfont (\alph{subfigure})}
            \end{subfigure} 
            \begin{subfigure}{.49\textwidth}
                \includegraphics[width=1\linewidth]{pic}
                \caption{ }
                \label{fig7b}
            \end{subfigure}
            \caption{My caption}
            \label{f7}
        \end{figure}
    \end{frame}

  • 不需要，graphicx本身已经提供了beamerbeamer
  • 也不需要像[h!]中的放置选项beamer，因为它beamer禁用了浮动机制。
