Consider the following simplified code. 

\documentclass[pstricks,border=2cm]{standalone}

\usepackage{pst-eucl}
\psset{saveNodeCoors}

%\def\xy#1{!\psGetNodeCenter{#1} #1.x #1.y}% cannot  be reflected!
\def\xy#1{!N-#1.x N-#1.y}

\begin{document}
\begin{pspicture}[showgrid](-3,-1)(3,3)
    \pstGeonode
        (2,0){A}
        (2,2){B}
    \nodexn{.25(A)+.25(B)+(0,2.5)}{C'}
    \pstGeonode(C'){C}
    \def\common{\psline(\xy{A})(\xy{B})(\xy{C})}%
    \pscustom
    {
        \common
        \reversepath
        \scale{-1 1}
        \common
        \closepath
    }
\end{pspicture}
\end{document}

enter image description here

Why can't the abscissa and ordinate obtained from \psGetNodeCenter be reflected?

  • You'd have to redefine the (same) nodes after setting \scale{-1 1} or \psset{xunit=-1}, I think. – Werner Dec 29 '13 at 20:34
  • I curious about what happened to your other question related to these points. I've been playing around with it and found it rather perplexing. Did you come up with a solution? – A.Ellett Dec 29 '13 at 23:05
  • I got very different results just by changing the border.... So it sems there is still a question: "Why must you go through code as you do below?" It seems something isn't working correctly with \nodexn. – A.Ellett Dec 29 '13 at 23:10
  • I think you should repost it as a question about \nodexn or report it as a bug. – A.Ellett Dec 29 '13 at 23:12

    I was trying to get it work outside of \pscustom and I was still getting strange values. I boiled my examples down to just loading pstricks and pst-node. I did not load pst-eucl. Performance differed if I used article document class. If I used standalone I got different results depending on how border was set in the class options. – A.Ellett Dec 30 '13 at 00:52
  • This is the same behavior as explained in http://tex.stackexchange.com/a/163411/33933 : I would consider closing this question as duplicate because it is about the difference between saveNodeCoors and \psGetNodeCenter. – Christoph Mar 03 '14 at 23:53
