尝试通过敲击来调整这个答案:https://tex.stackexchange.com/a/134297/3929具有蛇形装饰的路径。
有点效果,但我希望曲线的粗细均匀。下图中的曲线看起来或多或少像是用书法笔画的。
有任何想法吗?

\usetikzlibrary{fadings}%
\usetikzlibrary{decorations.pathmorphing}
\begin{tikzfadingfrompicture}[name=custom fade]%
\path(-0.2cm,0.2cm) rectangle (1.2cm,2.5cm); % Arrow line is an overlay!
\pgfinterruptboundingbox
\draw[

答案1
代码在问题中链接的 percusse 的答案对我来说实际上不起作用。我猜这是由于 TikZ 的变化。从 TikZ 的角度来看,2013 年基本上是古代历史。
我认为这里的问题在于你不希望 TikZ 像默认那样适应淡入淡出。那么你只需要确保一切都适合以获得预期的结果。
注意
line around/.style={
decoration={
pre=curveto,
pre length=0*#1,
post length=#1,
},
},
line around=3pt,
相当于
decoration={
pre=curveto,
pre length=0pt,
post length=#3pt,
},
并且我不完全确定此代码背后的想法是什么,因此为了简单起见,我在示例中将其删除。
\documentclass[tikz,border=10pt,multi]{standalone}

\usetikzlibrary{fadings,decorations.pathmorphing}
\begin{tikzfadingfrompicture}[name=custom fade]%
\path [fill=transparent!100] (-5mm,-10mm) rectangle (5mm,10mm);
\draw[

\end{tikzfadingfrompicture}
\begin{document}
\begin{tikzpicture}
\path[
path fading=custom fade,
fit fading=false,

但迄今为止,这并不令人满意。
