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

Jo.
