Greetings.
Previewing Latex fragments is one cool feature. However, I have one
problem tailoring it to my use.
In my emacs config file I now have:
(plist-put org-format-latex-options :foreground "white")
(plist-put org-format-latex-options :scale 2)
These seem to set the correct properties, because my value of
org-format-latex-options is
(:foreground "white" :background default :scale 2 :html-foreground "Black" :html-background "Transparent" :html-scale 1.0 :matchers
("begin" "$1" "$" "$$" "\\(" "\\["))
The scale factor property works just fine: I get a larger
preview. Unfortunately changing foreground has no effect. The default
black foreground - which I still get - is pretty useless for me, because
my default background in buffers is dark blue.
Any tips?
Jarmo

This works for me but in the context that I also change the background
to black (which does not necessarily match my Emacs background...). Try
that just to see? It may be a LaTeX issue.

Hello,
Here is mine. But I live with a black background. You might have trouble
with the table environment though. For some mysterious reason, although
the background changes,the foreground in the table environment remains black.
(setq org-format-latex-options '(:foreground "White" :background "Black" :scale 1.8
:html-foreground "Black"
:html-background "Transparent" :html-scale 1.1 ))
HTH,
Jeremie

This seems to be a compatibility issue with the forest package in
Latex. The problem is demonstrated and explained in the org file
below. I don't know yet what the solution is.

# ---------------------------------------------------------------------
#+LATEX_HEADER: \usepackage{forest}
* \LaTeX{} fragments: package ~forest~ confuses foreground color setting
Interestingly enough, the foreground color set by
#+BEGIN_SRC elisp
(plist-put org-format-latex-options :foreground "White")
#+END_SRC
does /not/ change the foreground color in this simple invariant
equation \[ ab^n = ab\cdot b^{n-1} \] if ~usepackage{forest}~ is
included in \LaTeX{} header. When package ~forest~ is not used,
setting the color works just fine.
To make things a bit more complicated, after commenting or
uncommenting the ~LATEX_HEADER~ line, you need to remove the
contents of directory ~ltximg~ in the working directory to see the
difference, because the system caches the generated images of the
equations there.
