TikZ：仅在路径的一部分上有圆角

Question

rounded corners=<length>如果我只想要部分（封闭的）路径，那么正确的语法是什么？

\documentclass[margin=5mm]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[]
\draw[rounded corners=5.5] (77:1.5) arc (77:180-77:1.5) -- ++(0,1) 
-- ++(-0.5,0.5) -- ++(0.5,0.5) % here rounded corners...
-- ++(0,1) -- ++(0.5,0) -- cycle;
\end{tikzpicture}
\end{document}

Answer 1

您可以在路径中途打开圆角，稍后再将其关闭：

\documentclass[margin=5mm]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[]
\draw (77:1.5) arc (77:180-77:1.5) -- ++(0,1) 
[rounded corners=5.5] -- ++(-0.5,0.5) [sharp corners]  -- ++(0.5,0.5) % here rounded corners...
 -- ++(0,1) -- ++(0.5,0) -- cycle;
\end{tikzpicture}
\end{document}
