I attach one at the end of the message. 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 Uwe Brauer
