I recall something changed about the handling of color/pyxgraphics
recently but can't find it. So I'm asking for help here. (I've bisected
and solved the epsfile problem myself already, so this is only fair :) )
The following fragment used to work:
text.set(mode="latex")
text.preamble(r"""%
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{stone}
\usepackage{multicol}
\usepackage[english]{babel}
\usepackage[pyx]{xcolor}
\usepackage[pyx]{graphicx}
\usepackage[14]{sizedef}
\usepackage{sizesub}
\usepackage{xspace}
%
\parindent=0pt
\parskip=3.5ex
\multicolsep=0pt
\hyphenpenalty=10000\exhyphenpenalty=10000
\newcommand{\tline}[1]{\hglue0pt\hbox to \textwidth{#1}}
\newcommand{\topic}[1]{{\rmfamily\textbf{#1:}}}
%
""") #, [text.texmessage.ignore])
midgray = color.gray(128./255)
text.preamble(r"\definecolor{midgray}{gray}{%(gray)f}" % midgray.color)
lcdgray = color.gray(0.75)
text.preamble(r"\definecolor{lcdgray}{gray}{%(gray)f}" % lcdgray.color)
capgray = color.gray(0.25)
text.preamble(r"\definecolor{capgray}{gray}{%(gray)f}" % capgray.color)
(The Augsburg gang will recognize where this comes from...)
Most of the preamble lines shoud be irrelevant, of course, but waht do I
know.
Now I am getting the following with that:
File ".py", line 47, in <module>
text.preamble(r"\definecolor{midgray}{gray}{%(gray)f}" % midgray.color)
File "/home/mjg/src/pyx/pyx/text.py", line 1149, in preamble
self.execute(expr, texmessages)
File "/home/mjg/src/pyx/pyx/text.py", line 1023, in execute
raise TexResultError("unhandled TeX response (might be an error)", self)
pyx.text.TexResultError: unhandled TeX response (might be an error)
The expression passed to TeX was:
\definecolor{midgray}{gray}{0.501961}%
\PyXInput{5}%
After parsing the return message from TeX, the following was left:
*! Undefined control sequence.
<*> \definecolor
{midgray}{gray}{0.501961}%
! LaTeX Error: Missing \begin{document}.
So, \definecolor is not defined (while it used to be). What's going on?
Cheers,
Michael
