Subject: /usr/share/images/desktop-base/spacefun-grub.png too visually complex for grub's scaler

Date: Thu, 2 Dec 2010 16:38:10 -0400

[Message part 1 (text/plain, inline)]

Package: desktop-base
Version: 6.0.1
Severity: normal

The image is 1024x768, so on a display such as my netbook's 1024x600, it
has to be scaled. Grub2's image scaler does not do any smoothing
apparently, the result is similar to the attached screenshot.png 
(taken using zxgv, but a similar effect, although I don't think the text
looked as bad in grub). Notice particularly the swirl. The fine, smooth
white lines outlining it do not survive scaling well and become jagged, and
the result looked very unpolished when I saw it for the first time at boot.

Hey,

did you try to use the widescreen alternative?

It still needs to be scaled down to may laptop's screen (in both
dimensions), so I still see a jagged border around the swirl, and some
degredation around the vertical risers in the text.

Until grub supports svg (not sure it's a great idea either though :),
I'm not sure we can do anything about that. Shipping an alternative for
each and every resolution isn't really doable, so there will be some
resize anyway.

You can use images that do not contain fine detail (in highly
contrasting colors) that degrades badly when scaled. The moreblue theme
did not have this problem to any significant degree. Removing the fine
white lines from around the swirl and removing the small-font text would
eliminate the worst part of this problem.

I'm adding Valessio to CC: in case he missed the thread on

Sorry, but I'm not quite know how to solve it.

Maybe having a high-resolution image. Using a script with  
"imagemagick" to cut and resize the ideal format.

I have tried to solve this, if this is OK with Valessio.

Please take a look at:

<http://wiki.debian.org/DebianArt/desktop-base-bugfix605732>

I hope this helps.

It may sound obvious, but grub2 config set default gxfmode to 640x480,
which results in ugly rendering.

Did you try raising GRUB_GFXMODE in /etc/default/grub ? 
(don't know whether 1024x600 is supported, but 800x600 would definitely render
better than default resolution) ? 

BTW, do you think it would be reasonable to set higher default resolution
in grub2 when using themes ? (it would be a shame all the art efforts cannot be
rendered correctly by default)

Valessio gave his OK for this bugfix.

So can we consider this problem solved? Or is there anything else that 
should be changed in the grub pictures?

best regards
Ulrich

Ok, I'll take the iso ones from that page, so the readability is
improved too.

fixed 605732 7.0.0
thanks

We don't use spacefun anymore, and I believe the new branding is quiet
enough to not pose a problem.

Thanks!

Looks like the bug report was missing a mail to 605732-done@bugs.debian.org to 
actually be closed.
