How to export LaTeX amsmath align bmatrix to ODT?

How to export LaTeX amsmath align bmatrix to ODT?

[edgar]

Hello,

I have been making progress with my export procedure to ODT. I would 
like to know if someone knows how to export the following LaTeX block to 
ODT correctly:

\[\begin{align} \begin{bmatrix} a = 1 & b=2 \\ c=3 & d = 4 \end{bmatrix} 
\end{align}\]

\[\begin{align}  a = & 1 + 2 + 3 + 4 \\ c = &  4 \end{bmatrix} 
\end{align}\]

As always, any help is welcome :) .

By the way, I tried with latexmlmath and mathtoweb.jar without success.

Ok. I got it (with a minor glitch). If someone can help me to get the 
right colors on the screen (my screen is black; the \tensor symbol is 
also black), I would appreciate it. Now I can export to ODT with my 
custom symbols and the bmatrix environment.

For the record, I had modified org-preview-latex-process-alist to get 
custom symbols, and this got in the way of the LaTeX bmatrix environment 
(I don't know how; I was loading a file with with :latex-header as 
"\\input{preamble.tex}").

My partial answer (it is partial, because the \tensor preview renders in 
a different color than the rest of symbols): Instead of modifying 
org-preview-latex-process-alist, the answer I modified 
org-format-tex-header. I added the following at the end of M-x 
customize-variable org-format-tex-header (I leave it here for posterity; 
I added some symbols: tensor, derivative, vector, Roman numeral, etc.)

I'm a bit lost here. In particular, I'm able to export the example above
out-of-the-box, provided I add "#+options: tex:dvipng" or some such in
the document.

I don't think you need to modify `org-format-latex-header' at all. There
is `org-latex-packages-alist' for that.

So, is there a bug in the ODT export back-end? If so, could you post an
ECM? Loads of LaTeX code doesn't help understanding the issue.

Check out org-format-latex-options.  I have, for the same or similar scenario:

#+begin_src emacs-lisp
  (setq org-format-latex-options
        '(:foreground "white" :background "black" :scale 3
                      :html-foreground "Black" :html-background "Transparent"
                      :html-scale 1.0
                      :matchers ("begin" "$1" "$" "$$" "\\(" "\\[")))
#+end_src

Thanks, Eric. Unfortunately, that did not work. It does change the 
background and foreground colors, but the \tensor symbol is now 
"invisible" (it is black, and the background is also black). The rest of 
the equation looks fine.

Strange.  Maybe post an ECM for others to experiment with?

Hello Eric,

What is an ECM and how do I produce it? (this is a honest question).

Sorry: French for minimal but complete example so that others can try to
reproduce the problem.  See the FAQ:

Yes, indeed, without modifying any variable, the code exports correctly, 
but I had modified org-preview-latex-process-alist to include my 
symbols.tex file like this:

     I managed to get the special symbols by

     1. M-x customize-variable org-preview-latex-process-alist
     2. Doing [Ins] into the dvipng (or imagemagick) section
     3. typing :latex-header in the Key: field
     4. typing "\\input{./symbols.tex}" in the Value: field

After I did that, some symbols would export correctly, but others would 
not. I was not importing any LaTeX packages within that file. I use this 
file to export PDF (through LaTeX: C-c C-e l p). One of the things that 
did not work was the matrix environment. I thought that it was better to 
start a new question regarding the matrix, because I thought it was 
independent of the symbols.

This is related to the following:

I don't really know how to modify org-latex-packages-alist to have a 
latex command like this in my tex file:

\newcommmand{\mysymbol}[1]{\mathrm{my_{#1}}}

I do have a bunch of packages with custom options over there :P !

I think that the only bug is that I don't know how to use it very well 
;) . I don't know what a ECM is :S , sorry. I typed ECM emacs on a web 
search engine, and only got ECB. Is it the same? If you are willing to 
tell me how to get one, I'll do my best.

Right now, I am having a glitch on the screen. I get some of my custom 
symbols in black (all the others are in light gray) on a black 
background (my screen has a black background; see attached picture: 
there is an I with two tildes underneath next to the p). I would like to 
know if you or someone else can help me to get a light gray on that 
symbol too. I suspect that it may have to do with the stackengine 
(LaTeX) package, because all of my other symbols are doing well. This is 
the snippet of code that I have in org-format-latex-header to define the 
\tensor symbol

\newcommand{\tensor}[1]{
   
\stackunder[0pt]{\stackunder[1pt]{#1}{\scriptscriptstyle\sim}}{\scriptscriptstyle\sim}}

I also opened a new emacs with -Q, did a (require 'org), yanked my 
configuration of org-format-latex-header and created a new Org file. 
Then, changed the theme to a dark one and I typed $\tensor{F}$ $a$. For 
the $\tensor{F}$ I get a white square with a black font face. For the 
$a$ I get the same set of colors as the theme (dark background, 
light-gray font face).

Thank you a lot for you time!

I fixed a bug in "ox-odt.el". Now, when using convertion to png, you can
add

 #+latex_header: \newcommmand{\mysymbol}[1]{\mathrm{my_{#1}}}

Hopefully, it should solve, at least partly, your issue.
