Tikz 的阴影键为弯曲路径创建实体形状而不是阴影 - 如何创建阴影？

Question

我正在制作字形。我希望最终的形状有阴影。

为箭头创建阴影的效果与预期一致。在底部的弯曲路径下创建阴影则不行。当我按下按键时，反而会创建一个奇怪的纯灰色填充drop shadow。如何将阴影放置在正确的位置*，就像箭头一样？

• = 任意偏移对我来说都有效。我将其用于shadow xshift=.725pt, shadow yshift=-.725pt箭头。

Answer 1

这是匆忙做出的一些尝试。因此可能需要进行一些微调。

\documentclass[border={1pt -15pt 1pt 1pt},convert={density=3000,outext=.png}]{standalone}
\usepackage{tikz}
\usetikzlibrary{fadings,shadows}
\tikzfading[name=fade,right color=black!10, left color=black]
\definecolor{rgray}{RGB}{188,188,214}
\begin{document}
\begin{tikzpicture}
\draw[path fading=fade, postaction={drop shadow={shadow scale=1, shadow xshift=0.5pt, shadow yshift=-0.5pt, opacity=.8, fill=gray!40}}, fill opacity=.9, draw=rgray] 
(1.475,0.11) .. controls (1.45,.825) and (1.45,0.9875) .. (2,1)
-- (2,1) -- (2,.95) -- (2.23,1.1) -- (2,1.25) -- (2,1.2) 
.. controls (1.45,1.1) and (1.45,1.3) .. (1.475,0.011);
\path[fill=white]
(1.475,0.11) .. controls (1.45,.825) and (1.45,0.9875) .. (2,1)
-- (2,1) -- (2,.95) -- (2.23,1.1) -- (2,1.25) -- (2,1.2)
.. controls (1.45,1.1) and (1.45,1.3) .. (1.475,0.011);
\end{tikzpicture}
