The issue are the options
in
call-process "dvipng" nil nil nil
After trying out different configurations, I found out that
the option
"-D" dpi
Does not work well with Xemacs.
So
(call-process "dvipng" nil nil nil
"-fg" fg "-bg" bg
;; "-D" dpi
;; "-x" scale "-y" scale
"-T" "tight"
"-o" pngfile
dvifile)
is ok, however the back and foreground setting as generated
by org-dvipng-color, even with Julian Bradfield's patch do
not produce very nice results. In my Xemacs setting it is better to
comment them out.
So there are two small changes necessary to make
org-preview-latex-fragment work in Xemacs. One is the above
change, the other
(font-height (face-font 'default))
instead of
(font-height (get-face-font 'default))
I can send a patch against 7.8.03
