我正在使用文档类“beamer”在 LaTeX 中创建演示文稿。我的演示文稿包含大量图片（超过 26 张）。LaTeX 文档编译正确，直到图片数量少于 26 张。后来，我开始收到错误“计数器太大”。我正在使用包“graphixc”和“subfig”。我可以获得该包的信息阿尔法可以使用。但是，我无法正确使用它？我该如何修复此错误，以便我可以将我的所有图表都包含在演示文稿中？随函附上最小工作示例 (MWE)。提前感谢您。

答案1
看来您喜欢用字母对图片进行编号，为此您使用了subfig标题。要将编号扩展到 26 个（子）图片，您只需进行\thesubfig相应定义：
\renewcommand\thesubfigure{\alphalph{\value{subfigure}}}
无关：文档类beamer加载包graphics和hyperref，所以您不需要再次加载它们。
完成 MWE：
\documentclass[demo]{beamer}
\mode<presentation> {
\usetheme{Madrid}
}
\graphicspath{{D:/Figures/}}
\usepackage{alphalph}
\usepackage{subfig}
\renewcommand\thesubfigure{\alphalph{\value{subfigure}}}
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables
\usepackage{natbib}
\usepackage{amsmath,amssymb,amsthm}

附录：
在您的评论之后，您不再完全清楚您喜欢如何对标题进行编号。现在我看到两种可能性：
- 标题已编号，但没有标题标签（例如“图”）
\documentclass[demo]{beamer}
\mode<presentation>
{
\usetheme{Madrid}
%----------------------------------------------------------------------------------------
% FIGURE STYLE
%----------------------------------------------------------------------------------------
\setbeamertemplate{caption}{(\insertcaptionnumber)\ \insertcaption} % <---
\setbeamerfont{caption}{size=\footnotesize} % <---
}
\graphicspath{{D:/Figures/}}
\usepackage{booktabs,
tabularx} % new
\newcolumntype{C}{>{\centering\arraybackslash}X}
\usepackage{natbib}
\usepackage{amsmath,amssymb,amsthm}
\usepackage{gensymb}
%----------------------------------------------------------------------------------------
% TITLE PAGE
%----------------------------------------------------------------------------------------
\title[SAR-MS Fusion]{Pre-synopsis Seminar}
\author{\small Samadhan C. Kulkarni} % Your name
\institute[College of Engineering, Pune]
{
College of Engineering, Pune \\
\medskip
}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}[allowframebreaks]
\frametitle{Overview}
\tableofcontents
\end{frame}
\section{Introduction}
\subsection{Definition}
\begin{frame}
\begin{figure}
\begin{tabularx}{\linewidth}{CC}
\includegraphics[scale=0.1]{coep_logo.jpg}
\caption{Noisy Image}
&
\includegraphics[scale=0.1]{coep_logo.jpg}
\caption{Subset}
\end{tabularx}
\end{figure}
\end{frame}
\begin{frame}
\begin{figure}
\begin{tabularx}{\linewidth}{CC}
\includegraphics[scale=0.1]{coep_logo.jpg}
\caption{Whatever}

\includegraphics[scale=0.1]{coep_logo.jpg}
\caption{Figure 4}
\end{tabularx}
\end{figure}
\end{frame}
\end{document}
结果是：
-
- 带有编号标签的标题。在这种情况下，您需要将上面的 MWE 替换
\setbeamertemplate{caption}{(\insertcaptionnumber)\ \insertcaption}为：
- 带有编号标签的标题。在这种情况下，您需要将上面的 MWE 替换
\setbeamertemplate{caption}[numbered]
它的编译结果是：
笔记：
- 正如您所看到的，两种情况下的图像都被插入到
tabularx表格环境中。 - 如果您仍然希望在某些图中使用子图，那么您需要在上面的 MWE 中在序言中加载包
subfig，然后使用它，例如：
\begin{frame}
\begin{figure}
\subfloat[Noisy Image]{\includegraphics[scale=0.1]{coep_logo.jpg}}
\hfil
\subfloat[Subset]{\includegraphics[scale=0.1]{coep_logo.jpg}}
%
\caption{Figure with two sub figures}
\end{figure}
\end{frame}
