Evaluating LaTeX source blocks had an issue where header options would be
ignored when exporting to SVG; this appears to have been addressed in
246df88. I have patched this commit into my 8.2.7c installation. While
the headers now seem to work, I’ve noticed that LaTeX still doesn’t like
the generated temporary files when SVG-output is selected. Below is an
example which fails to work when SVG output is chosen, but which will
work when PNG is used.
#+HEADERS: :headers '("\\usepackage{tikz}" "\\usetikzlibrary
{shapes,arrows,positioning}")
#+BEGIN_src latex :file test.svg :imagemagick
\begin{tikzpicture}
\node {quux quux quux};
\end{tikzpicture}
#+END_SRC
The generated temporary LaTeX file is shown below.
\documentclass[preview]{standalone}
\def\pgfsysdriver{pgfsys-tex4ht.def}
\usepackage[usenames]{color}
\usepackage{tikz}
\usepackage{color}
\usepackage{listings}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,positioning}
\begin{document}\begin{tikzpicture}
\node {quux};
\end{tikzpicture}\end{document}
By default, LaTeX will choke on this with a lot of undefined command
errors. I have no clue about PGF, but I’ve noticed that if I insert
«\usepackage{pgf}» before the «\def\pgfsysdriver» line, this will resolve
those errors. Should this be done in ob-latex too?
After these errors are resolved, though, LaTeX will still complain about
an option clash for the color package. At first I thought this might be
because the colors package is imported twice. But apparently PGF will
also import colors, so that both the «\usepackage{pgf}» and the «\def
\pgfsysdriver» had to come after «\usepackage[usenames]{color}».
Best regards,
T.
