Thanks for your fix, Werner. Good catch! "ctest --verbose --tests-regex
pstex" works for me now (on Debian stable). It appears this device driver
is generally working now. However, I noticed some obvious scale errors in
my experiments with it (see below) which tweaked my memory of a fix
recommended by Bill Paxton more than two years ago. When I tried the fix
(now possible because the device is working again), the scale problems
disappeared so I have just now committed Bill's fix.
It appears all this device needs now is some documentation of exactly how to
use its results. Here is a first attempt at that, but I hope somebody
improves on this and transcribes it to doc/docbook/src/drivers.xml since
I am really short of time.
The results from this device are two files. One is an EPS file (e.g.,
x01c.eps) of the plots without the characters, and the other is a file of a
latex fragment (e.g., x01c.eps_t) which imports that EPS file and uses latex
commands to render the characters in a way that is perfectly aligned with
the EPS file.
You may use the generated files with the following latex code:
****x01c.tex*****
\documentclass{article}
\usepackage[dvips]{graphicx}
\begin{document}
\input{x01c.eps_t}
\end{document}
****x01c.tex*****
Then you generate a postscript file from this using the commands:
latex x01c.tex
dvips -f <x01c.dvi >x01c.ps
The results look good (aside from an obvious bounding-box problem) and should
be useful for Latex enthusiasts.
