小页面环境未对齐

Question

我正在尝试并排显示两个小页面。以下是代码（还有：平均能量损失)：

\begin{frame}[t]%
    \fbox{\begin{minipage}[t][\textheight][t]{.48\textwidth}
        All the previous questions are as relevant for cybernetic systems as they are for `simple' systems.

        A principled mathematical framework for the ontology and phenomenology of systems is given by \textbf{categorical system theory} (CST):
    \end{minipage}}
    \begin{minipage}[t][\textheight][t]{.48\textwidth}
        \begin{center}
            \fbox{
                \includegraphics[height=.85\textheight]{CST.png}
            }\\
            \cite{myers2021book}
        \end{center}
    \end{minipage}
\end{frame}

我不明白为什么会发生这种情况：

我使用上一张幻灯片中的相同代码来对齐两页文本，并且运行正常。有什么提示吗？

\documentclass{beamer}

\begin{document}

\begin{frame}[t]%
    \fbox{\begin{minipage}[t][\textheight][t]{.48\textwidth}
        All the previous questions are as relevant for cybernetic systems as they are for `simple' systems.

        \begin{center}
            \fbox{
                \includegraphics[height=.85\textheight,width=\linewidth]{example-image}
            }\\
            ...[example]...

    \end{minipage}
\end{frame}
\end{document}

Answer 1

我会使用投影仪柱：

% !TeX TS-program = lualatex

\documentclass[14pt]{beamer}

% Presento style file
\usepackage{config/presento}

% custom command and packages
\input{config/custom-command}

\begin{document}


\begin{frame}[t]%
  \begin{columns}[onlytextwidth,T]
    \begin{column}{.48\textwidth}
      \fbox{\parbox{\textwidth}{
        \centering
            All the previous questions are as relevant for cybernetic systems as they are for `simple' systems.
        
            A principled mathematical framework for the ontology and phenomenology of systems is given by \textbf{categorical system theory} (CST):
      }}
    \end{column}
    \begin{column}{.48\textwidth}
      \centering
            \fbox{\href{http://davidjaz.com/Papers/DynamicalBook.pdf}{\includegraphics[width=.9\textwidth]{images/skeleton.jpg}}}
      
            \cite{myers2021book}
    \end{column}
  \end{columns}
\end{frame}



\end{document}

Answer 2

您显示的图像左侧第一行文本的基线与右侧图像的基线对齐。

这意味着两个小页面都是顶部对齐的，并且以文本和图像作为第一项。

\documentclass{beamer}

\begin{document}

\begin{frame}[t]%
    \fbox{\begin{minipage}[t][\textheight][t]{.48\textwidth}
        All the previous questions are as relevant for cybernetic systems as they are for `simple' systems.

        A principled mathematical framework for the ontology and phenomenology of systems is given by \textbf{categorical system theory} (CST):
    \end{minipage}}
    \begin{minipage}[t][\textheight][t]{.48\textwidth}
            \fbox{
                \includegraphics[height=.85\textheight,width=\linewidth]{example-image}
            }\\
            ...[example]...
    \end{minipage}
\end{frame}
\end{document}

如果您\vspace在第二个小页面的顶部添加一个，则参考点将移动到第一个项目，因此左列文本将移到更高的位置。center环境（如代码片段中所示）添加了这样的 vspace 节点。

\documentclass{beamer}

\begin{document}

\begin{frame}[t]%
    \fbox{\begin{minipage}[t][\textheight][t]{.48\textwidth}
        All the previous questions are as relevant for cybernetic systems as they are for `simple' systems.

        A principled mathematical framework for the ontology and phenomenology of systems is given by \textbf{categorical system theory} (CST):
    \end{minipage}}
    \begin{minipage}[t][\textheight][t]{.48\textwidth}
\begin{center}
            \fbox{
                \includegraphics[height=.85\textheight,width=\linewidth]{example-image}
            }\\
            ...[example]...
\end{center}
    \end{minipage}
\end{frame}
\end{document}

Answer 3

右侧小页面的参考点是图片的底部。

您可以添加\vspace*{...}以设置不同的参考点。在第一个小页面中，它应该是0pt，在第二个小页面中，您必须通过\fboxrule和进行备份\fboxsep。

\documentclass{beamer}

\begin{document}

\begin{frame}[t]
\frametitle{Cybernetic systems}

\fbox{\begin{minipage}[t][0.7\textheight][t]{.48\textwidth}
   \vspace*{0pt}
   All the previous questions are as relevant for cybernetic systems as they
   are for `simple' systems.

   A principled mathematical framework for the ontology and phenomenology of
   systems is given by \textbf{categorical system theory} (CST):
\end{minipage}}
\begin{minipage}[t][\textheight][t]{.48\textwidth}
   \centering
   \vspace*{-\fboxsep}\vspace*{-\fboxrule}
   \fbox{%
     \includegraphics[height=.65\textheight,width=0.9\textwidth]{example-image-9x16}%
   }

   \cite{myers2021book}
\end{minipage}

\end{frame}

\end{document}
