如何在手册 97.12 中更改为虚线？

Question

此示例取自手册pgf​。它完美地解释了我想要做的事情，但我需要由虚线组成的矩形的边框。

\begin{tikzpicture}
   \pgfsetcornersarced{\pgfpoint{5mm}{5mm}}
   \pgfpathrectanglecorners{\pgfpointorigin}{\pgfpoint{3cm}{2cm}}
   \pgfusepath{stroke}
\end{tikzpicture}

谢谢！

Answer 1

请阅读下一节\pgfsetdash：

\documentclass{article}
\usepackage{pgf}
\begin{document}
\begin{pgfpicture}
  \pgfsetcornersarced{\pgfpoint{5mm}{5mm}}
  \pgfpathrectanglecorners{\pgfpointorigin}{\pgfpoint{3cm}{2cm}}
  \pgfsetdash{{3pt}{2pt}}{0pt}
  \pgfusepath{stroke}
\end{pgfpicture}
\end{document}

TikZ 中也是一样：

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \draw[
    rounded corners=5mm,
    dash pattern=on 3pt off 2pt,
  ] (0, 0) rectangle (3, 2);
\end{tikzpicture}
\end{document}
