New look for Emacs-23.0

New look for Emacs-23.0

Hi,

Please find attached a new set of splash images for Emacs-23.0. These
are anti-aliased versions of the current ones for Emacs and gnus. The
idea is that as font aliasing is a great improvement for next release,
I think that the visual and aesthetic aspect of Emacs should be also
slightly updated.

'splash.*' images should go to the 'etc/images/' directory; 'gnus.*'
images to 'etc/images/gnus/' ('svg' images are fully scalable and they
include copyright and licensing information; 'png' images were
directly obtained from the respective 'svg' images).

Below there are also a couple of patches, for files 'lisp/startup.el'
and 'lisp/gnus/gnus.el' files. These patches add support for 'svg' and
'png' image formats on those displays that support them. Otherwise,
current images are used ('xpm' or 'bmp' format, depending on the
display capabilities).

They are very nice and look much better that the default xpm splash
screen (at least on Windows).

A minor glitch: The lower left end of the `s' looks like a serifed
form which doesn't match the appearance of all other letters -- the
anti-aliased version pronouces this stronger than the old one.  With
other words, it shouldn't have a serif but rather a hook (like the
hook in the lower left of the `a').

I think it's fine.

Thank you for improving the look of Emacs.

Looks fine to me.  Could someone help check this in?

Thanks.

Just to let you know, you might have used this SVG version:
http://commons.wikimedia.org/wiki/Image:Emacs-logo.svg. Looks a bit
tidier regarding some curves in the GNU head area. This logo may also be
found somewhere on gnu.org site already. Gnus logo is also available:

This code still needs to be tuned to correctly pay attention to the
color depth: testing display-planes only when we don't support SVG and
PNG doesn't make any sense.

May be what's wrong is that 'x-display-planes' is used to test whether
'splash8.xpm' or 'splash.xpm' must be displayed. I think it's wrong
because both images are not so different. Judging by the name of these
images, I did suppose they had different color depth. Surprisingly,
I've found this:

splash.xpm
**************************************************
static char *splash[] = {
/* width height num_colors chars_per_pixel */
"   270   217        4            1",
/* colors */
". c None",
"# c #c64e3b",
"a c #000000",
"c c #2076c1",
**************************************************

splash8.xpm
**************************************************
static char * splash_xpm[] = {
"270 217 4 1",
" 	c None",
".	c #C64E3B",
"+	c #000000",
"@	c #2076C1",
**************************************************

So, in terms of color depth, what's the difference between these images?

Indeed, I also saw that the 2 images are low-color versions, so the test
didn't make much sense, but the situation now is very different because
the new files use up many colors, so the display-depth should be used to
guard the use of those new high-color images.

You're right, so my proposal is to use the following patch and to delete the
file 'splash8.xpm' from the repository.

That sounds good.  Can someone make this change?
