[O] resize png in org-toggle-latex-fragment

[Uwe Brauer]

Hello

I am using GNU emacs 25.0.50, and 8.3.1.

The png generated ny org-toggle-latex-fragment are too small for my
taste.

I found two solutions
http://emacs.stackexchange.com/questions/3387/how-to-enlarge-latex-fragments-in-org-mode-at-the-same-time-as-the-buffer-text


(defun update-org-latex-fragments ()
  (org-toggle-latex-fragment '(16))
  (plist-put org-format-latex-options :scale text-scale-mode-amount)
  (org-toggle-latex-fragment '(16)))
(add-hook 'text-scale-mode-hook 'update-org-latex-fragments)


(defun update-org-latex-fragment-scale ()
  (let ((text-scale-factor (expt text-scale-mode-step text-scale-mode-amount)))
    (plist-put org-format-latex-options :scale (* 4.3 text-scale-factor))))

(add-hook 'text-scale-mode-hook 'update-org-latex-fragment-scale)

None of them worked for me.

Does somebody know a different one?

Thanks
