GRAPHICS CONTRIBUTIONS TO KNOPPIX
==========================================================================

Since our painting/drawing capabilities are very limited (you can guess
from the Knoppix 2.1 wallpaper...), Knopper.Net offers the following to
all interested graphic artists:

 You send us a graphics package for inclusion in Knoppix, and, if the
 package is accepted for a Knoppix release, we promote your website or
 business via a link that you can place on the desktop wallpaper (see
 below) in return. 


GENERAL TERMS AND CONDITIONS
============================

Most important, Licenses: All graphics must be licensed by and from the
author(s) for "free distribution, for non-commercial as well as
commercial use, without restrictions" for inclusion in Knoppix and
derivates thereof. Especially, it must be possible for third parties to
distribute and sell remastered Knoppix CDs or DVDs including the
graphics, unchanged or in modified form. A good starting point for a
Knoppix-compatible graphics license is this version of the Creative
Commons:

http://creativecommons.org/licenses/by/2.5/deed.en

All graphics should NOT include the Knoppix or Knopper.Net logo or any
version numbers, since we would like to use the same pictures for
different versions and derivates, and fill in these items by ourselves
(using Gimp) on demand later.


TECHNICAL SPECIFICATIONS:
=========================

Wallpaper
=========

Format: 1024x768 Pixels, suitable for post-processing with GIMP.

Colors: Preferably dark, not too much contrast, because of readability
of icons and texts. The picture should still look good in 16 bit color
depth. The leftmost and bottom part of the picture should leave
sufficient space for desktop icons and the KDE menu bar. The right
border of the picture would be optimal for holding the authors copyright
and web address in a decent and unobtrusive way ("designed by:
webaddress", for example). KDE Desktop theme is usually "plastik" or
"keramik", which doesn't mean that the picture has to match this style.

File size: When compressed as PNG (good for pictures without gradients)
or JPEG (good for pictures with gradients), the wallpaper should not
exceed 500kB, since this could cause a performance loss in loading speed
from CD or DVD otherwise.


Bootscreen:
===========

Format: 640 x 400 Pixels in 16 Colors (!), Color No. 7 should be a light
color, because it's the text color in the isolinux splash screen.

Colors: No gradients if possible, since the picture will be
runlength-encoded.

File size: Compressed GIF, max. 12kB.

Additional: There should be enough free room for fitting a "KNOPPIX
versionnumber" logo and a very short help, which will be added using
GIMP without changing colors.


ksplash_top.png (possibly also other ksplash files)
===================================================

Format: 400x265 Pixels, suitable for postprocessing with GIMP.

Colors: of your choice, but should still look OK with a 16bit indexed
color table.

Additional: Usually, the KDE-splashscreen is just the somewhat changed
and downscaled wallpaper. It doesn't have to be that way, though.


Background graphics for the HTML help files
===========================================

Format: ca. 800x600 Pixels, maybe larger. Picture will be placed as text
background via CSS, non-repeating. It should probably fade-out in black
at the bottom and right corners.

Additional: On top of the graphics, there should be space for a Knoppix
headline and writing of about 100 pixels in width, 20 pixels in height.


Taking part in the knoppix-graphics contest:
============================================

Send contributions to: knoppix-graphics (at) knopper (dot) net. Since
most graphics file formats are already compressed, it is sufficient to
just attach the individial files instead of creating an archive (which
may be subject to accidentially get deleted by virus/spamfilters on the
intermediate mail gateways anyways). But most important: Please make
sure to include a plaintext LICENSE file that matches the conditions
mentioned above. Otherwise we will have to delete the pictures, unseen,
following german copyright law.

(If mailtraffic exceeds a certain amount, we will probably provide
a webform for upload instead of an email address).
