This works quite well, in a geeky kind of way ;-) However, I do want to display a couple of equations and using latex fragments is the most appealing mechanism. When I try to use org-preview-latex-fragment, the latex image is generated. Unfortunately, as I use a black background on my display, I cannot see the fragment as it is being generated with black text on a transparent background by default. Note, I am using dvipng for the image conversion. I can customise org-format-latex-options to fix this, or so I thought. No matter what I do, the resulting latex fragment has black text. The problem appears to be that the -fg option to dvipng does not work so it doesn't matter how I customise org-format-latex-options. Can anybody suggest a workaround (without changing the actual latex itself)? I can customise the above variable to set the background for latex images to white, which at least allows the equations to be seen, but this is a mildly ugly solution. :( And ruins any geek street cred I might have had ;-) Thanks, eric -- : Eric S Fraga, GnuPG: 0xC89193D8FFFCF67D : in Emacs 24.3.50.1 and Org release_7.9.3d-874-gf11acc
