[pstricks] Re : AlgParser inside raw coordinates (! PS code)

[mluque5130 at aol.com]

 Christophe,
    
This code works. But this is perhaps not the answer you want? It must be improved ...

\documentclass{article}
\usepackage{pstricks}
\begin{document}
\SpecialCoor
\begin{pspicture}[showgrid=true](5,5)
\pstVerb{/Pi 3.14159 def
         /rpn {AlgParser cvx} def
         /xA (5*cos(Pi/4)) rpn def
         /yA (5*sin(Pi/4)) rpn def}
  \psdot(! xA  yA)
\end{pspicture}
\end{document}

M.L.

Sujet : [pstricks] AlgParser inside raw coordinates (! PS code)










Hello all,

I don't understand why I get a postscript error with the felowing code.
(expression) AlgParser cvx doesn't seem to put a number on the stack.
Maybe I misunderstand something.

\listfiles
\documentclass{article}
\usepackage{pstricks}
\begin{document}
\SpecialCoor
\def\lpar{(}
\def\rpar{)}
\begin{pspicture}[showgrid=true](5,5)
  \psdot(!5 45 cos mul 5 45 sin mul)
  \psdot(!
    \lpar 5*cos\lpar 45\rpar\rpar\space AlgParser cvx 
    \lpar 5*sin\lpar 45\rpar\rpar\space AlgParser cvx)
\end{pspicture}
\end{document}
