[pstricks] Difficulties with pst-pdf

Fri May 15 05:12:01 CEST 2009

Herbert,

Ouch! Did not know this, as our textbook now have 8 chapters to date  
and lots of pstricks that is not in a pspicture or psmatrix envrionment.

So, what to do?

As I may have mentioned in the past, we have this Optimath system  
we've built (perl, shell scripts, pdflatex, mysql, html):

http://msenux.redwoods.edu/cgi-bin/online/s09/OTlogin.cgi

It serves up quizzes, homework, etc., and builds the files on the  
fly, fully randomized. It is filled with metapost graphics that are  
built on the fly. We'd like to include pstricks graphics as well. One  
of the scripts of our system uses a perl script to take this file:

This is all served off a linux server. What we need to know is how to  
compile the latter file so that all the pstricks output will shop up  
in the resulting pdf file. We're not wedded to pst-pdf, but are just  
looking for a robust way to compile the latter file. We need some  
solid advice.

Thanks.

pst-pdf scans only the pspicture and psmatrix environment.

\documentclass[12pt]{article}

\usepackage{pst-pdf}
\usepackage{pstricks}
\def\psFrame[#1](#2)(#3){\begin{pspicture}(#2)(#3)\psframe[#1](#2)(#3) 
\end{pspicture}}

\begin{document}
In the shaded box that follows, enter the inequality symbol $<$ or $>$
so that the resulting inequality is a true statement.

$-3\quad\psFrame 
[linewidth=2pt,fillstyle=solid,fillcolor=lightgray,framearc=0.2](0,0) 
(0.5,0.5)\quad
-2$

\end{document}
