粗蓝色箭头

我想创建如图所示的粗箭头来连接图形，但我不知道如何在投影仪上实现它。有什么想法吗？ 在此处输入图片描述

这是我用于 tikz 的代码：

\begin{tikzpicture}[scale=0.8]
%       \includegraph777ics[height=6.5cm]{terre.png};
\node (fullwt) at (0,7){\includegraphics[height=2cm]{fullwt.png}};%

\node (hybrid1) at (3.5,5.5){\includegraphics[height=2cm]{hybrid1.png}};
%
\node (hybrid2) at (7,4){\includegraphics[height=2cm]{hybrid2.png}};
%
\node (fullpv) at (10.5,2.5){\includegraphics[height=2cm]{fullpv.png}};

\draw [>=latex, ->] (fullwt) {} (hybrid2);
\end{tikzpicture}

答案1

这是一个提案，它利用了twisted arrow来自这个答案。样式定义很长，但好处是绘制扭曲箭头变得像说一样简单

\draw[twisted arrow={color=blue}] (A.east) to[bend left=50] (B.110);

箭头将跟随指定的路径。其所有（大多数）参数都存储在 pgf 键中，因此您可以进行调整。
