http://orgmode.org/manual/Math-formatting-in-HTML-export.html

Hello the list,

Unfortunately, I do not know how to use Mathjax in order to convert any
mathematical symbol or any proof in html. Therefore the only solution that
I see is to use imagemagick.
But the line

 #+OPTIONS: tex:imagemagick

in my setup gives always corrupted png images and I do not succeed to
understand why.
I would be thankful if someone could tell me how to configure my emacs
in order to use imagemagick to convert any proof in png image to
export it in html.

Thanks !

Jo.

  What version of Emacs and org mode are you using?
  
  What is your configuration?
  
  What action did you perform on what document?
  
  What did you want and expect to have happen with that action?
  
  What happened instead?

      This works perfectly fine for me with both dvipng (my default choice)
      and imagemagick.  The problem may be in your LaTeX installation: what
      fonts are used etc.?
      
      What does the PDF or DVI for this LaTeX file:
      
      --8<---------------cut here---------------start------------->8---
      % Created 2014-10-13 Mon 12:43

      \neg A \to (A \to B)
      \end{equation}
      % Emacs 24.4.50.1 (Org mode 8.3beta)
      \end{document}
      --8<---------------cut here---------------end--------------->8---
      
      look like?

        I have just tested 
        and it works. I conclude that the problem comes from imagemagick. 
        
        But dvipng does not succeed to make png images of proofs via bussproofs.sty. 
        
        For example, I do not succeed to transform this proof into a png image: 
        
        \begin{prooftree}
        \def\fCenter{\ \Rightarrow\ }
        \AxiomC{}
        \RightLabel{\scriptsize{Ax.}}
        \UnaryInf$A \to \bot, \bot \fCenter \bot$
        \RightLabel{\scriptsize{$L\neg$def.}}
        \UnaryInf$ \neg A, \bot \fCenter \bot$
        \RightLabel{\scriptsize{$R\neg$}}
        \UnaryInf$\bot \fCenter \neg \neg A$
        \AxiomC{}
        \RightLabel{\scriptsize{Ax.}}
        \UnaryInf$A, \bot \fCenter \bot$
        \RightLabel{\scriptsize{$R\neg$}}
        \UnaryInf$\bot \fCenter \neg A$
        \RightLabel{\scriptsize{$R\land$}}
        \BinaryInf$\bot \fCenter \neg \neg A \land \neg A$
        \end{prooftree}
        
        
        I succeeded also to do it with Gnus by adding #+LaTeX_HEADERS:
        \usepackage{bussproofs} on the top of the message, and no it does not no
        more... that's another problem...

          Have a look at the following variable and note the SNIPPET argument:

            Thanks Eric.
            
            I have tested this solution that works with imagemagick and html export. I
            have added these lines in my init.el :
            
            ; Include the latex-exporter
            (require 'ox-latex)
            ;; Add minted to the defaults packages to include when exporting.
            ;(add-to-list 'org-latex-packages-alist '("" "minted"))
            ;; Tell the latex export to use the minted package for source
            ;; code coloration.
            (setq org-latex-listings 'minted)
            ;; Let the exporter use the -shell-escape option to let latex
            ;; execute external programs.
            ;; This obviously and can be dangerous to activate!
            (setq org-latex-pdf-process
                  '("xelatex -shell-escape -interaction nonstopmode -output-directory
            %o %f"))
            
            and it works.
            
            But now it does not work in my Gnus if I want to include some png images of
            proofs... I have to deleted these "dangerous lines"...
            
            I do not understand why I need minted and shell-escape...
            
            Best wishes

              I don't know why you need minted (I have not followed the conversation),
              but to use minted you *need* -shell-escape: minted requires running an
              external program (pygments), but tex does not like doing that for
              security reasons - the -shell-escape option gives tex permission to run
              such an external program.

                Thanks for this explanatio Nick. I need minted, strangely, in order to get
                png images in html export. If I try to avoid the use of minted, the png
                images are corrupted...
                
                Best wishes
                
                Jo.

              Sorry, I missed this the first time around.  What does gnus have to do
              with this?  You were talking about exporting to HTML but never mentioned
              gnus in the original post.
              
              If you are trying to write an html based email, you should be looking at
              different functionality than exporting.  Check out org-mime-htmlize, for
              instance.  Exporting creates files which reference other files (for
              images).  Messages are different.

                Yes, I'm using precisely org-mime-htmlize with gnus when want to send
                messages with png images. But with minted in my setup (to export correctly
                html), the preview function does not work and then org-mime-htmlize
                fails...
                
                Again thanks !
                
                Best wishes

                  Interesting.  The following has three LaTeX equations, one without any org LaTeX directives, one for inline use and one for LaTeX blocks.  Only the first works.
                  
                  (please accept my apologies for sending an HTML formatted email to this list ;-)
                  
                  * test
                  
                  This is a test of the equations:
                  
                  \begin{equation}
                  y = \sqrt{x}
                  \end{equation}
                  
                  Alternatively, using LaTeX directives: first, the single line ~#+latex~ directive for an equation inline, say,
                  #+LATEX: y = f(x)
                  followed by a begin/end latex block:
                  
                  * summary
                  
                  The last one has disappeared completely.  The second is there in the raw email but has not been translated.  Only the first case works.  The export engine must work differently when exporting as a string?  It is indeed surprising that the whole begin/end latex block is removed from the raw text version, as you indicated in your OP.
                  
                  This behaviour does seem rather strange.  Looking at org-mime.el, it is not obvious (to me) what is wrong.
