[pstricks] A bug in saveNodeCoors

[Donut E. Knot]

Hi folks,

According to Christoph in his answer http://tex.stackexchange.com/a/156100/19356, there is a bug in saveNodeCoors that can be fixed as follows.

\documentclass[preview,border=1cm]{standalone}
\usepackage{pst-tools}
\usepackage{pst-node}
\makeatletter
% the following is the definition from pst-node.tex v 1.30, with the mentioned changes
\def\pst at newnode#1#2#3#4{%
\pst at killglue
\leavevmode
\pst at getnode{#1}\pst at thenode
\pst at Verb{
  \ifPst at saveNodeCoors
    \ifx\relax#3\relax 
      0 0 
    \else 
      gsave 
        tx at Dict begin 
          STV CP T
        end
        #3 \tx at UserCoor
      grestore
    \fi 
%  startGlobal
%  \tx at UserCoor
  /N-#1.y\space exch def
  /N-#1.x\space exch def
%  endGlobal
  \fi
  \pst at nodedict
  {#3}
  \ifx\psk at name\relax false \else \psk at name true \fi
  \pst at thenode
  #2
  {#4}
  \tx at NewNode
  end 
}%
%
\global\let\psk at name\relax%
\pstree at nodehook%
\global\let\pstree at nodehook\relax}
\makeatother

\psset{saveNodeCoors}

\begin{document}
\begin{pspicture}(5,3)
    \pnode(1,1){A}
    \rput(0,2){\psPrintValue{N-A.x}}
    \rput(0,1){\psPrintValue{N-A.y}}
    %
    \nodexn{(1,1)}{B}
    \rput(2,2){\psPrintValue{N-B.x}}
    \rput(2,1){\psPrintValue{N-B.y}}
    % 
    \pnode(A){C}
    \rput(4,2){\psPrintValue{N-C.x}}
    \rput(4,1){\psPrintValue{N-C.y}}
\end{pspicture}
\end{document}


Hopefully the PSTricks maintainers consider this patch whether or not it should be implemented in the next update of pstricks.tex.


Thank you in advance.
