使用矩阵缩放 tikzpicture 的最佳方法

我在一份文档中找到了以下图形，我想将其放入一些投影仪幻灯片中。该图形太宽，幻灯片放不下，所以我想将所有内容缩小 2 倍。

\begin{frame}
\begin{figure}
\centering
\begin{tikzpicture}[text depth=0.5ex, text height=2ex]
\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 2/.style={minimum width=3em, nodes={rectangle, draw}}]
at (0.5,0) 
(mat1)
{
b_{n+1} \\
{} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat1, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 2/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat2)
{
b_n \& \ldots \& b_{i+1} \& b_i \& b_{i-1} \& \ldots \& b_2 \& b_1 \\
{} \& {\hspace{1.5cm}} \& {} \& {} \& {} \& {\hspace{1.5cm}} \& {} \& {} \\
};
\node[above=0pt of mat2]
  (cellb) {$B_\mathcal{C}$};

\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 1/.style={minimum width=3em, nodes={rectangle, draw}}]
at (0,-3) 
(mat3)
{

b_{n+1} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat3, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat4)
{
{} \& {\hspace{1.5cm}} \& {} \& {} \\
b_{m_{n- \delta}} \& \ldots \& b_{m_2} \& b_{m_1} \\
};
\node[below=0pt of mat4]
  (celld) {$B_U$};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat4, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat5)
{

b_{k_{\delta}} \& \ldots \& b_{k_2} \& b_{k_1} \\
};
\node[below=0pt of mat5]
  (celle) {$B_R$};

\begin{scope}[shorten <= -2pt]

\end{figure}
\end{frame}

我尝试过 [scale=0.5]，但无济于事。最方便的方法是什么？

我不确定，如果我猜对了所有软件包，我仍然会收到字体警告。但是，您通过选择单位将大多数元素缩放到字体大小em。因此，要减小尺寸，您必须更改字体大小，我在第 9 行中这样做了\tiny：

\documentclass[]{beamer}
\usepackage{tikz}
\usetikzlibrary{matrix, positioning, arrows}

\begin{document}
\begin{frame}
\begin{figure}
\centering
\tiny
\begin{tikzpicture}[text depth=0.5ex, text height=2ex]
\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 2/.style={minimum width=3em, nodes={rectangle, draw}}]
at (0.5,0) 
(mat1)
{
b_{n+1} \\
{} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat1, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 2/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat2)
{
b_n \& \ldots \& b_{i+1} \& b_i \& b_{i-1} \& \ldots \& b_2 \& b_1 \\
{} \& {\hspace{1.5cm}} \& {} \& {} \& {} \& {\hspace{1.5cm}} \& {} \& {} \\
};
\node[above=0pt of mat2]
  (cellb) {$B_\mathcal{C}$};

\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 1/.style={minimum width=3em, nodes={rectangle, draw}}]
at (0,-3) 
(mat3)
{
{} \\
b_{n+1} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat3, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat4)
{

b_{m_{n- \delta}} \& \ldots \& b_{m_2} \& b_{m_1} \\
};
\node[below=0pt of mat4]
  (celld) {$B_U$};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat4, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat5)
{

或者另一个选择是扩展节点以及你的 tikz 图片的字体scale=0.7, every node/.style={scale=0.7}

\documentclass[]{beamer}
\usepackage{tikz}
\usetikzlibrary{matrix, positioning, arrows}

\begin{document}
\begin{frame}
\begin{figure}
\centering

\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 2/.style={minimum width=3em, nodes={rectangle, draw}}]
at (0.5,0) 
(mat1)
{
b_{n+1} \\
{} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat1, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 2/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat2)
{

{} \& {\hspace{1.5cm}} \& {} \& {} \& {} \& {\hspace{1.5cm}} \& {} \& {} \\
};
\node[above=0pt of mat2]
  (cellb) {$B_\mathcal{C}$};

\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 1/.style={minimum width=3em, nodes={rectangle, draw}}]
at (0,-3) 
(mat3)
{

b_{n+1} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat3, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat4)
{

b_{m_{n- \delta}} \& \ldots \& b_{m_2} \& b_{m_1} \\
};
\node[below=0pt of mat4]
  (celld) {$B_U$};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat4, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat5)
{

b_{k_{\delta}} \& \ldots \& b_{k_2} \& b_{k_1} \\

transform canvas={scale=0.7}您可以使用以下示例来缩放图形

\documentclass[]{beamer}
\usepackage{tikz}
\usetikzlibrary{matrix, positioning, arrows}
\begin{document}
\begin{frame}
\begin{figure}
\centering
\begin{tikzpicture}[transform canvas={scale=0.7}]
\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 2/.style={minimum width=3em, nodes={rectangle, draw}}]
at (-6,0) 
(mat1)
{
b_{n+1} \\
{} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat1, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 2/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat2)
{
b_n \& \ldots \& b_{i+1} \& b_i \& b_{i-1} \& \ldots \& b_2 \& b_1 \\
{} \& {\hspace{1.5cm}} \& {} \& {} \& {} \& {\hspace{1.5cm}} \& {} \& {} \\
};
\node[above=0pt of mat2]
  (cellb) {$B_\mathcal{C}$};

\matrix[matrix of math nodes, anchor=west, row sep=-\pgflinewidth, column sep=-\pgflinewidth, row 1/.style={minimum width=3em, nodes={rectangle, draw}}]
at (-6.5,-3) 
(mat3)
{
{} \\
b_{n+1} \\
};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat3, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat4)
{
{} \& {\hspace{1.5cm}} \& {} \& {} \\
b_{m_{n- \delta}} \& \ldots \& b_{m_2} \& b_{m_1} \\
};
\node[below=0pt of mat4]
  (celld) {$B_U$};

\matrix[matrix of math nodes, ampersand replacement=\&, right=of mat4, row sep=-\pgflinewidth, column sep=-\pgflinewidth,row 1/.style={minimum width=3em, nodes={rectangle, draw}}] 
(mat5)
{
{} \& {\hspace{1.5cm}} \& {} \& {} \\
b_{k_{\delta}} \& \ldots \& b_{k_2} \& b_{k_1} \\
};
\node[below=0pt of mat5]
  (celle) {$B_R$};

\begin{scope}[shorten <= -2pt]
\draw[*->]
    (mat5-1-1.north) -- (mat2-2-1.south);
\draw[*->]
    (mat4-1-1.north) -- (mat2-2-3.south);
\draw[*->]

\end{tikzpicture}
\end{figure}
\end{frame}
