如何用 tikz 製作 suncross？

Question

我的問題是關於標題的。我想讓箭頭指向太陽十字，就像這？我可以自己製作箭頭，你能幫我製作太陽十字嗎？

Answer 1

繪製一個內部帶有十字符號的圓形節點，類似訊號調製器的乘法器

\documentclass{article}
\usepackage{tikz} 
\usetikzlibrary{calc}

\begin{document}
    \begin{tikzpicture}[cross/.style={path picture={ 
                \draw[black,line width=1pt]
                (path picture bounding box.south east) -- (path picture bounding 
        box.north west) (path picture bounding box.south west) -- (path picture 
          bounding box.north east);
        }}]
        
        \node [draw,circle,cross,minimum width=1 cm,line width=1pt](B) at (3,0){}; 
        \draw[<-,line width=1pt,stealth-] (B.south 
        west)to[out=225,in=75,looseness=1.3]($(B.south)+(-3,-6)$);
        
    \end{tikzpicture}
    
\end{document}
