Re: [O] unwelcome tmp and ltxpng directories in my home

[Joseph Vidal-Rosset]

Thank you Nick for this helpful email.

The good news is that I have succeeded to get the png image in /tmp/ltxpng/ directory.

The bad news is that my gnus persist in saying to me that there is no /tmp/ltxpng/image.png ...  here is the message :

Loading reftex...done

I attach the orgtex6500qb1.tex  and orgtex6500qb1.log

Again thanks for this help.

Best regards,

Jo.

When you do org-preview-latex-fragment, a ltxpng subdirectory is created
under the directory that contains the org file. So if you have
/home/joseph/foo.org and you preview it, you are going to get
/home/joseph/ltxpng as a subdirectory. That is controlled by the setting
of org-latex-preview-ltxpng-directory however:

,----
| org-latex-preview-ltxpng-directory is a variable defined in `org.el'.
| Its value is "ltxpng/"
|
| Documentation:
| Path to store latex preview images.
| A relative path here creates many directories relative to the
| processed org files paths.  An absolute path puts all preview
| images at the same place.
`----

So you could customize it to store all the png files into /tmp/ltxpng
e.g.

No idea where the tmp/ directory comes from, but I don't think it's from
the preview.
