[Tex/LaTex] AUCTeX preview font size too small

auctexemacspreviewwindows

I have Emacs 24 and AUCTex on a Windows 7 machine, however the preview font size is just way too small. Is there a way to make them bigger?

enter image description here

Add the following to your .emacs file:

(set-default 'preview-scale-function 1.2)

Adjust the value according to your needs.

Worked through the problem and have three points to stress:

\PreviewEnvironment should not work in a tex file's preamble.
One way to add custom environments is by adding full \PreviewEnvironment{..} entries after the last string of the default Preview Default Preamble string (expected to be ]{preview}[2004/11/05]). It's equivalent for .emacs: (setq preview-default-preamble (quote ("\\RequirePackage[" ("," . preview-default-option-list) "]{preview}[2004/11/05]" "\\PreviewEnvironment{center}" "\\PreviewEnvironment{enumerate}"))), where center and enumerate are example custom environments. Alternatives are (preview-latex.pdf, p. 11):
- including custom environments in local file variables
- a configuration file in the project's directory
M-x preview-environment (C-c C-p C-e) works only for the customized environments (see 2) and environments from preview-default-option-list.

I was having this same problem when I stumbled across this post. I was able to fix it the following way:

Note, I am using Emacs23.3.1, AUCTeX 11.86, Ubuntu 11.10, Gnome3.2.1

Open a .tex file (or make one). I will assume that you are using Emacs23, using an Xwindow (Mine is in Gnome). Go to the menu bar and do:

Preview -> Customize -> Browse Options

In this buffer, do:

Preview GS -> Preview GS options -> [click on the little arrow to show the options] -> del -dSAFER

C-x C-s to save, and reload Emacs. Previews should work now!
