使用 axodraw4j 包绘制费曼图时出错

Question

我试图绘制一个简单的费曼图，但画得不正确。当我编译它时，动量标签没有画出线条。

这是我的代码：

\documentclass[12pt,twoside]{report}

\usepackage{axodraw4j}
\usepackage{pstricks}
\usepackage{color}

\begin{document}

\begin{center}
\fcolorbox{white}{white}{
  \begin{picture}(176,146) (183,-125)
    \SetWidth{1.0}
    \SetColor{Black}
    \Line[arrow,arrowpos=0.5,arrowlength=16,arrowwidth=10,arrowinset=1](342,20)(270,-52)
    \Line[arrow,arrowpos=0.5,arrowlength=16,arrowwidth=10,arrowinset=1](198,-124)(270,-52)
    \Line[arrow,arrowpos=0.5,arrowlength=16,arrowwidth=10,arrowinset=1](342,-124)(270,-52)
    \Line[arrow,arrowpos=0.5,arrowlength=16,arrowwidth=10,arrowinset=1](198,20)(270,-52)
    \Text(180,-34)[lb]{\Large{\Black{$\textbf{k}_1$}}}
    \Text(180,-88)[lb]{\Large{\Black{$\textbf{k}_2$}}}
    \Text(324,-88)[lb]{\Large{\Black{$\textbf{k}_3$}}}
    \Text(324,-34)[lb]{\Large{\Black{$\textbf{k}_4$}}}
  \end{picture}
}
\end{center}

\end{document}

请帮忙。谢谢！
