mathjax vs. imagemagick

mathjax vs. imagemagick

[Joseph Vidal-Rosset]

[-- Attachment #1: Type: text/plain, Size: 339 bytes --]

Hello,

In order to convert a tikzpicture into html webpage, one needs
#+OPTIONS: tex:imagemagick
and it means that the other equations are no more converted via Mathjax.

Is there a mean to combine the use of imagemagick only for tikzpicture, and
keeping the use of Mathjax to read the other equations in the html file?

Best wishes

Jo.

Hi,

You don't need to set the tex:imagemagick option globally. With the
example bellow, the HTML export should use Mathjax to render math
fragments:

#+begin_src org
  ,#+TITLE: Test
  ,#+AUTHOR: Blah
  ,#+LATEX_CLASS: article
  ,#+LATEX_CLASS_OPTIONS: [american]
  #
  # Setup tikz package for both LaTeX and HTML export:
  ,#+LATEX_HEADER: \usepackage{tikz}
  ,#+PROPERTY: header-args:latex+ :packages '(("" "tikz"))
  #
  ,#+PROPERTY: header-args:latex+ :imagemagick (by-backend (latex nil) (t "yes"))
  ,#+PROPERTY: header-args:latex+ :exports results :fit yes
  
  ,* One Diamond
  
  ,#+name: diamond
  ,#+header: :iminoptions -density 600 -resample 100x100
  ,#+header: :file (by-backend (latex "diamond.tikz") (t "diamond.png"))
  ,#+begin_src latex :results raw file
    \begin{tikzpicture}
      \draw (1,0) -- (0,1) -- (-1,0) -- (0,-1) -- cycle;
    \end{tikzpicture}
  ,#+end_src
  
  ,#+attr_latex: :float nil :width ""
  ,#+results: diamond
  
  ,* LaTeX
  
  Inline math follows \(\left\{ x \right\}\)…
  
  ,* COMMENT setup
  
  ,#+name: setup
  ,#+begin_src emacs-lisp :results silent :exports none
    (defmacro by-backend (&rest body)
      `(case (if (boundp 'backend) (org-export-backend-name backend) nil) ,@body))
  ,#+end_src
  
  # Local variables:
  # eval: (org-sbe "setup")
  # End:
  
#+end_src

Regards,

Many thanks for this help Nicolas. I do not succeed  to adapt your example
to my file. I am afraid that it is too complicated for me.

I meet always difficulties with html export, and now it is a failure of
bibtex2html...

Thanks again

Best regards

Jo.
