为什么两条“曲线”不具有相同的坐标？

Question

\documentclass[border=15pt,pstricks,12pt]{standalone}
\usepackage{pst-intersect}
\begin{document}
\begin{pspicture}[showgrid](3,2)
{\psset{linestyle=dashed}
\pssavepath{MyPath}{\pscurve(0,2)(0,0.5)(3,1)}
\pssavebezier{MyBez}(0,0)(0,1)(1,2)(3,2)(1,0)(3,0)
\psintersect[showpoints]{MyPath}{MyBez}}

\psclip{\pscurve(0,2)(0,0.5)(3,1)}{
\pscustom[fillstyle=vlines]{\pssavebezier{hi}(0,0)(0,1)(1,2)(3,2)(1,0)(3,0) 
\gsave \grestore}}
\endpsclip
\end{pspicture}
\end{document}

两个数字不一致。为什么呢？

Answer 1

你有很多尾随空格：

\documentclass[border=15pt,pstricks,12pt]{standalone}
\usepackage{pst-intersect}
\begin{document}
    \begin{pspicture}[showgrid](3,2)
    {\psset{linestyle=dashed}
        \pssavepath{MyPath}{\pscurve(0,2)(0,0.5)(3,1)}%%%
        \pssavebezier{MyBez}(0,0)(0,1)(1,2)(3,2)(1,0)(3,0)%%%%
        \psintersect[showpoints]{MyPath}{MyBez}}%%%%%
    \psclip{\pscurve(0,2)(0,0.5)(3,1)}{%
        \pscustom[fillstyle=vlines]{%
            \pssavebezier{hi}(0,0)(0,1)(1,2)(3,2)(1,0)(3,0)}}
    \endpsclip
    \end{pspicture}
\end{document}
