preserving images, and image contrast

hi,
I had two questions about preview-latex:

1. Currently, when I kill emacs, all the preview images (and IIRC, the .efmt
file too), are deleted. I have customized the auto-cache variable to be on, but
I suppose the cache is only on a per-session basis? Is there a way to make
previe-latex not delete all those images at the end of the session? If the
previews are up-to-date (or even reasonably so) at the end of the session, I'd
like a way to reuse them at the next start-up, instead of going through the
whole thing again.

2. Currently, images for inline math are low on contrast, and somewhat blurry. I
compensate for that somewhat by setting preview-scale-function to the number
1.25. Even so, I'd be interested to know a way to address the problem directly.
(The background for my default face in emacs is beige, but the problems persist
even for a white background.)

This is on CVS emacs (precompiled binary from crasseux.com) running on WinXP.
Thanks,

Rajneesh.

Here's the state info, in case it's useful. sorry for any bad indentation, gmane
complains if any lines are longer than 80 characters(?!). I tried filling it
sensibly in emacs before posting, but didn't do a very good job.

Customize that and add

         -gamma 1.4

or so (default 1, higher number=more contrast).

His settings clearly don't make use of dvipng.  If he has dvipng
installed, he could use

M-x customize-variable RET preview-image-type RET

to set the image type to "dvipng", and then your advice might make a
difference.

Actions in multifile documents.

Hello,

is it -- or will it be -- possible to perform a certain set of
actions for all files of a multifile document?  For instance, I
would like to find all occurrences of a string in my document.  I
know that package `edit-utils' supports searching in many buffers
in its buffer and window management section. Thus to use that
facility, I would have to open all files belonging to a document
(which yields another possible application of doing things for
all files in a multifile document).

Another feature I would like to see, is to have a function that
lets one directly jump to the file referred to by an `\include'
macro after having placed the cursor into the macro's argument.
So far, I am not aware that any of these features are part of the
multifile handling in AUCTeX.

Franz.

Ah, sorry. I didn't see "dvipng" in image-types so I mistakenly thought
dvipng was enbled by default when choosing 'png.

AUCTeX Folding: Feature Request

Hi there,

regarding the wonderful folding function of AUCTeX, I would like to
suggest two minor improvements.

\documentclass{scrartcl}
\begin{document}
\begin{description}
\item[A label] It has a nice description of a variable
  X\textsubscript{foo} and Y\textsuperscript{bar}.
\end{description}
\end{document}

Folding this shows two things: First, the item label is hidden, which
may lead to confusion. Instead of
* It has a nice description of a variable
it would be nice to see
*[A Label] It has a nice description of a variable

Second, wouldn't it be nice to process the textsu[b|per]script in the
same way it is the case in math mode for "^" and "_"?

Should one or both features be already existant, I would like to
apologise and ask for a hint how to activate.

Best
Joachim

reftex-search-document is an interactive autoloaded Lisp function in `reftex-global'.
[Arg list not available until function definition is loaded.]

Regexp search through all files of the current TeX document.

ffap is an alias for `find-file-at-point' in `ffap.el'.
(ffap &optional FILENAME)

Find FILENAME, guessing a default from text around point.
If `ffap-url-regexp' is not nil, the FILENAME may also be an URL.
With a prefix, this command behaves exactly like `ffap-file-finder'.
If `ffap-require-prefix' is set, the prefix meaning is reversed.
See also the variables `ffap-dired-wildcards', `ffap-newfile-prompt',

If your document structure is reflected in your file structure, then
reftex-toc will help you navigate quickly.

Take a look at the documentation for RefTeX.

Best wishes,

Peter

Thanks friend, it worked.
