I am beginner in pst-opexp and I have a problem with positioning component. When I try no draw a lens in the position (2,1) (see code after), I get a lens in the position (1.92,1) (see figure). The gap of almost 0.08 unit annoys me. Does anyone have an explanation or, even better, a solution? Thank you very much. The code I use is

\documentclass[pstricks,margin=1cm]{standalone}
\usepackage{pst-optexp}
\begin{document}
\begin{pspicture}[showgrid](0,-0.3)(3,2.3)
  \pnodes(0,1){A}(4,1){B}
  \lens[abspos=2](A)(B)
\end{pspicture}
\end{document}

And the result is :

  • @eamy: Compiling your code (latex,dvips,ps2pdf) with \documentclass{article} and \usepackage{pst-optexp} produces a correct output on my machine.

Please update your TeX-Distribution, then it should work. It is a trailing space in showgirl
