使用 onslide 与 tcolorbox 在同一张幻灯片上显示四张图片

Question

我的问题是，我有两列幻灯片，tcolorbox每侧都包含一个图形。我尝试使用命令\onslide显示四张图片。这是我的代码：

\documentclass{beamer}
\usepackage{beamerthemesplit}
\usepackage{tikz}
\DeclareGraphicsExtensions{.pdf,.png,.jpg,.eps}
\usepackage{epsfig} 
\usepackage{epstopdf}
\usepackage{tcolorbox}
\graphicspath{{./figs/}}

\begin{document}
\begin{frame}[t]{Robotic Arm Applications}

    %   Robotic arms are typically used in industry. Their  applications include:
    \begin{columns}[c]
        %       \onslide<-2>{

            \column{2.2in}
            \onslide<1->\begin{tcolorbox}[width=\textwidth,colback={green},title={  \includegraphics[width=\textwidth,height=0.65\textheight]{Robot_welding}},colbacktitle=yellow,coltitle=blue,left=0mm,right=0mm,top=0mm,bottom=0mm,boxsep=1mm,arc=0mm,boxrule=0.5pt]
                \centering In Welding
            \end{tcolorbox} 

            \onslide<3->\begin{tcolorbox}[width=\textwidth,colback={green},title={      \includegraphics[width=\textwidth,height=0.65\textheight]{Robot_medical}},colbacktitle=yellow,coltitle=blue,left=0mm,right=0mm,top=0mm,bottom=0mm,boxsep=1mm,arc=0mm,boxrule=0.5pt]    
                \centering In Medical
            \end{tcolorbox}
            %               }
            %       \onslide<-1>{
            \column{2.2in}
            \onslide<2->\begin{tcolorbox}[width=\textwidth,colback={green},title={      \includegraphics[width=\textwidth,height=0.65\textheight]{Robot_handling}},colbacktitle=yellow,coltitle=blue,left=0mm,right=0mm,top=0mm,bottom=0mm,boxsep=1mm,arc=0mm,boxrule=0.5pt]    
                \centering Material Handling
            \end{tcolorbox} 
            %               }

            \onslide<4->\begin{tcolorbox}[width=\textwidth,colback={green},title={  \includegraphics[width=\textwidth,height=0.65\textheight]{Robot_automotive}},colbacktitle=yellow,coltitle=blue,left=0mm,right=0mm,top=0mm,bottom=0mm,boxsep=1mm,arc=0mm,boxrule=0.5pt]    
                \centering Automotive Industry
            \end{tcolorbox}

        \end{columns}
        %------------------

    \end{frame}

Answer 1

您必须用 替换\onslide，其中\only不覆盖未覆盖情况下的空间。此外，覆盖规范必须略作修改。

得出：

\usepackage{tikz}
\DeclareGraphicsExtensions{.pdf,.png,.jpg,.eps}
\usepackage{epsfig}
\usepackage{epstopdf}
\usepackage{tcolorbox}
