Beamer - 叠加使 tikzpicture 动起来

Question

以下代码使第一层相对于第二层和第三层定位不同（具有水平偏差）。

如果去掉colums和环境，这三个图形就处于相同的位置。columns

\documentclass[aspectratio=169]{beamer}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{multimedia}
\usepackage{booktabs}

\usetheme{AnnArbor}
\useoutertheme[right]{sidebar}
\useinnertheme{rounded}
\usecolortheme{dove}
\setbeamercovered{dynamic}
\setbeamercolor{alerted text}{fg=red}


\begin{document}

    \begin{frame}{uffaaa}
        \begin{columns}
            \begin{column}{0.7\textwidth}
            \end{column}
            \begin{column}{0.3\textwidth}
                \tikzsetnextfilename{figures/externalized/matCred}
                \includegraphics<1>[height=.8\textwidth]{figures/tikz/matrix/matCcirculdetailxox-red.tikz}
                \tikzsetnextfilename{figures/externalized/matCtrunc}
                \includegraphics<2>[height=.8\textwidth]{figures/tikz/matrix/matCcirculdetailxx.tikz}
                \tikzsetnextfilename{figures/externalized/matCtrunc-part}
                \includegraphics<3>[height=.8\textwidth]{figures/tikz/matrix/matCcirculdetailxx-partitioned.tikz}
            \end{column}
        \end{columns}
    \end{frame}


\end{document}

您可以使用代码

\begin{tikzpicture}
    \draw (0,0) rectangle (1,1);
\end{tikzpicture}

这三个*.tikz文件。

Answer 1

您必须注释掉后面的行\tikzsetnextfilename以避免插入虚假空格，例如

\tikzsetnextfilename{figures/externalized/matCred}%

代码：

\begin{filecontents*}{pic1.tikz}
\begin{tikzpicture}
    \draw[orange] (0,0) rectangle (1,1);
\end{tikzpicture}
\end{filecontents*}
\begin{filecontents*}{pic2.tikz}
\begin{tikzpicture}
    \draw[red] (0,0) rectangle (1,1);
\end{tikzpicture}
\end{filecontents*}
\begin{filecontents*}{pic3.tikz}
\begin{tikzpicture}
    \draw[red!50!blue] (0,0) rectangle (1,1);
\end{tikzpicture}
\end{filecontents*}
