tikz - 使用 to 命令进行形状跟踪

我使用 inkscape 跟踪工具得到了一个形状，它运行完美，但我想使用命令跟踪该形状以获得更简单的 tex 代码（目前使用 3 个点）。

它看起来不错，但与下面显示的原始图像仍略有不同：

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture}
        \node[anchor=south west,inner sep=0,opacity=0.8] (image) {
            \begin{tikzpicture}[y=0.80pt, x=0.80pt, yscale=-1,xscale=1,inner sep=0pt, outer sep=0pt]
                \draw[] (472.1277,432.2926) -- (462.9696,432.0051) -- (460.1149,421.0051) .. controls (454.0316,397.5641) and (444.2057,371.7197) .. (436.3491,358.4951) .. controls (427.0138,342.7815) and (413.1269,332.7275) .. (399.4016,331.7455) .. controls (378.6775,330.2627) and (362.5159,345.6736) ..

(208.2530,423.7551) -- (205.9828,432.5051) -- (196.6343,432.5051) .. controls (191.4925,432.5051) and (187.2857,432.2604) .. (187.2857,431.9613);
            \end{tikzpicture}           
        };
        \begin{scope}[x={(image.south east)},y={(image.north west)}]
            \begin{scope}[shift={(0.5,0.5)}]
                \draw[red,line width=1pt]
                (-0.435,-0.5) to[out=70,in=180] (-0.2,0.48) to[out=0,in=120] (0.015,-0.2);
            \end{scope}
        \end{scope}
    \end{tikzpicture}
\end{document}

希望调整代码以完全匹配原始形状！ 在此处输入图片描述

这是我做的贝塞尔曲线完美适合您的图片（可能需要缩放）但更简单： 贝塞尔曲线

\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}
    \begin{tikzpicture}
        \draw[line width=1pt]
            (0,0)       .. controls ++ (1.2,5.1)    and ++ (-1.1,0) ..
            (3.9,6)     .. controls ++ (2,0)        and ++ (-0.8,1) ..
            (7.6,1.8)   .. controls ++ (0.8,1)      and ++ (-2,0) ..
            (11.3,6)    .. controls ++ (1.1,0)      and ++ (-1.2,5.1) ..
            (15.2,0);
    \end{tikzpicture}
\end{document}
