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?
