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 |

Dear Michael, you probably missed to install pyx.def, color.cfg and graphics.cfg in your latex environment. This is required in order to force the graphics specials to be written in PyX style. You asked to do so by the [pyx] parameters to the xcolor and graphicx packages. (A quick and dirty solution could be to just place the three files in the current directory.) Usually you don't need to take care of all that when using the graphics/x package and/or the color package, as there is a hack in PyX to automatically choose the output style to be in PyX mode. However, this doesn't seem to work for the xcolor package (at least seemed broken when I just tried it).

The patch is trivial and this sort of issue, that the file suffix is important, was not expected at all. Fixed in changeset 3204.
