Hello

I made some progress in getting the function to work in
Xemacs.


The main problem seemed to be the function 
org-dvipng-color which is called in
org-create-formula-image.

The original formulation was 

(defun org-dvipng-color (attr)
  "Return an rgb color specification for dvipng."
  (apply 'format "rgb %s %s %s"
	 (mapcar 'org-normalize-color
		 (color-values (face-attribute 'default attr
		 nil)))))



Which does not work for Xemacs. Thanks to Julian Bradfield,
the solution seems to be:

(defun org-dvipng-color (attr)
  "Return an rgb color specification for dvipng."
  (apply 'format "rgb %s %s %s"
	 (mapcar 'org-normalize-color
 (color-rgb-components
     (face-property 'default (intern (substring (symbol-name attr) 1)))))))


However the png which were generated where to small to be
readable. I attach one at the end of the message.

So I tried out in GNU Emacs 21.3 to comment out
org-dvipng-color in org-create-formula-image.
org-preview-latex-fragment then still works, so  is not
necessary for generating the pngs.

So I tried to do the same in Xemacs but the formulas in the
png files keep being  too small.

What could be the reason for this behavior?
