投影仪幻灯片中的图形

Question

我正在尝试在投影仪中制作如下幻灯片：

% !TeX TS-program = xelatex
\documentclass{beamer}

\usecolortheme[rgb={0.7,0.2,0.2}]{structure}
\beamertemplateshadingbackground{red!70}{yellow!85}

\mode<article>{
    \usepackage{fullpage}
  \usepackage[bookmarks=false]{hyperref}
}

\mode<presentation>{
    %\setbeamertemplate{background canvas}[vertical shading][bottom=red!10,top=blue!10]
    \usetheme{Darmstadt}
}

\newtheorem*{remark6}{\footnotesize Prediction, The Main Purpose of Spatial Analysis}

\title[\textcolor{yellow}{Analysis of Non-Gaussian Spatial Models with Covariates Measurement Error}]

\begin{document}



\begin{frame}
\frametitle{\initfamily Prediction}
\begin{remark6}
\begin{columns}
\begin{column}{0.39\textwidth}
\vspace{-0.2cm}
\begin{alertblock}{}
            \begin{figure}
                    \center\vspace{-0.1cm}
                    \includegraphics<1>[width=\textwidth, height=0.75\textwidth]{F13.png}
                    \includegraphics<2>[width=\textwidth, height=0.75\textwidth]{F14copy.png}
                    \includegraphics<3>[width=\textwidth, height=0.75\textwidth]{F13.png}
                    \includegraphics<4>[width=\textwidth, height=0.75\textwidth]{F14copy.png}
            \end{figure}
\end{alertblock}
\end{column}
\begin{column}{0.49\textwidth}
\pause

但图形框的尺寸不同，如下：

和

我该如何修复它？

Answer 1

主要问题是图片后面的行尾未受保护。要解决这个问题，您必须%在每个图片后面添加一个（有关更多信息，请参阅行尾的百分号 (%) 有什么用？（为什么我的宏会产生额外的空间？））

---

我建议使用\centering而不是\center。事实上，你在图中根本不需要它，因为

1. 在 Beamer 中，图形默认居中

2. 您的图片跨越了整个文本宽度，因此居中没有区别

更进一步：你实际上不需要环境，figure因为你没有标题。这将节省你手动处理垂直空间的时间。

的定义remark6看起来有点可疑，为什么不简单地使用block？
