Why is pgnus starting xv?

Why is pgnus starting xv?

[Stefan Waldherr]

Hi,

I have a problem which occurs only in Emacs and not in XEmacs. pgnus starts xv
even if there is no image in a mail. For example, pgnus starts xv in Hrvoje's
recent mail <kigr9t5y7xz.fsf@jagor.srce.hr>. What could be the source of this
problem?

Thanks,
Stefan

Found that out myself: do not use gnus-article-display-x-face in
gnus-article-display-hook. Anyway, it is odd that gnus uses xv to display the
x-face.

Because that is the only way to display it under FSF Emacs?

Well, pgnus extracts x-face files into /tmp that are empty. Then xv is started
and -- of course -- bitches about the empty file. A bug?

Do you have the commands specified by gnus-article-x-face-command in
your path?

Well, it works under XEmacs. So the commands should be the same as under EMacs 
(I assume).

No, under XEmacs Gnus uses the built-in X-Face handlers.

Why odd?  Can Emacs display the x-face inline?  If not (though I
understand that the TM/semi group came up with a way to do it in a
MULE enabled Emacs, I couldn't get it to work in 20.3), an external
program is the only way to display it.

You can display x-face inline under Emacs20.{2,3} with the following
packages.

bitmap-mule :
ftp://ftp.jaist.ac.jp/pub/GNU/elisp/bitmap-mule/snapshots/bitmap-mule-SNAP.tar.gz

butmap-mule requires apel :
ftp://ftp.jaist.ac.jp/pub/GNU/elisp/apel/snapshots/apel-SNAP.tar.gz

If you want to display x-face like XEmacs, use x-face-mule :
http://www.jpl.org/elips/x-face-mule-0.24.tar.gz
(README.en is a little wrong...)

I can see x-faces inline under Emacs 20.{2,3}, pgnus-0.66.
