org-create-formula-image inserts LaTeX code:
...
(with-temp-file texfile
(insert latex-header)
(insert "\n\\begin{document}\n"
"\\definecolor{fg}{rgb}{" fg "}%\n"
(if bg
(concat "\\definecolor{bg}{rgb}{" bg "}%\n"
"\n\\pagecolor{bg}%\n")
"")
"\n{\\color{fg}\n"
string
"\n}\n"
"\n\\end{document}\n"))
...
that, /in principle/, would make it incompatible with the :standalone
argument (in my patch), which allows writing all LaTeX code from scratch
in the block content.
Anyway, it is true that org-babel-execute:latex has grown in a somewhat
irregular way. For example, I don't quite understand why the simple
output to PDF and the conversion to an image with :imagemagick live in
the same conditional:
(or (string= "pdf" extension) imagemagick)
I would propose three main branches in this function:
- A PDF branch, using org-format-latex-header with its valid options,
and other sub-branches with conversion from the PDF, for example, the
use of :imagemagick. Or you could even think of any possible
conversion process using a hypothetical :pdf-postprocess
- A branch for orf-create-formula-image
- a third branch to export to html, with org-babel-latex-htlatex.
Having three clearly differentiated branches would make the code easier
to maintain.
