缩放 tikz 箭头

Question

我想缩放一些 tikz 图像，scale=.5, every node/.style={scale=0.5}该图像适用于文本和除箭头之外的所有形状。如何正确缩放箭头？

这是我的 MWE：

\documentclass[tikz]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows}
\begin{document}

\begin{tikzpicture}[]
  \draw (0,0) rectangle (3,2);
  \draw[->,>=angle 60] (1,1)--(2,1);

  \begin{scope}[xshift=3.5cm, scale=.5, every node/.style={scale=0.5}]
    \draw (0,0) rectangle (3,2);
    \draw[->,>=angle 60] (1,1)--(2,1);
  \end{scope}

  \begin{scope}[xshift=5.5cm, scale=.25, every node/.style={scale=0.25}]
    \draw (0,0) rectangle (3,2);
    \draw[->,>=angle 60] (1,1)--(2,1);
  \end{scope}
\end{tikzpicture}

\end{document}

Answer 1

如果您缩放线宽，箭头也会缩放。

如果您不想缩放线宽，您可以使用arrows.meta缩放箭头。

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows.meta}
\begin{document}

\begin{tikzpicture}[]
  \draw (0,0) rectangle (3,2);
  \draw[-{Computer Modern Rightarrow[]}] (1,1)--(2,1);

  \begin{scope}[xshift=3.5cm, scale=.5]
    \draw (0,0) rectangle (3,2);
    \draw[-{Computer Modern Rightarrow[scale=0.5]}] (1,1)--(2,1);
  \end{scope}

  \begin{scope}[xshift=5.5cm, scale=.25]
    \draw (0,0) rectangle (3,2);
    \draw[-{Computer Modern Rightarrow[scale=0.25]}] (1,1)--(2,1);
  \end{scope}
\end{tikzpicture}

\end{document}
