2.26.1 Goals

b9dbd3
b9dbd3

This section describes the steps we followed to construct the

b9dbd3
Flame artistic motif. This section may be useful for anyone
b9dbd3
interested in reproducing the Flame artistic motif, or in
b9dbd3
creating new artistic motifs for The CentOS Project corporate visual
b9dbd3
identity (see section The <tt>`trunk/Identity'</tt> Directory).
b9dbd3

b9dbd3
b9dbd3
b9dbd3

2.26.2 Description

b9dbd3
b9dbd3

The Flame artistic motif was built using the flame filter of

b9dbd3
Gimp 2.2 in CentOS 5.5.
b9dbd3

b9dbd3

The flame filter of Gimp can produce stunning, randomly generated

b9dbd3
fractal patterns. The flame filter of Gimp gives us a great oportunity
b9dbd3
to reduce the time used to produce new artistic motifs, because of its
b9dbd3
"randomly generated" nature. Once the artistic motif be created, it
b9dbd3
is propagated through all visual manifestations of CentOS Project
b9dbd3
corporate visual identity using the <tt>`centos-art.sh'</tt> script
b9dbd3
(see section The <tt>`trunk/Scripts/Bash'</tt> Directory) inside the CentOS Artwork Repository.
b9dbd3

b9dbd3

To set the time intervals between each new visual style production, we

b9dbd3
could reuse the CentOS distribution major release schema.  I.e., we
b9dbd3
could produce a new visual style, every two years, based on a new
b9dbd3
"randomly generated" flame pattern, and publish the whole corporate
b9dbd3
visual identity (i.e., distribution stuff, promotion stuff, websites
b9dbd3
stuff, etc.) with the new major release of CentOS distribution all
b9dbd3
together at once.
b9dbd3

b9dbd3

Producing a new visual style is not one day's task. Once we have

b9dbd3
defined the artistic motif, we need to propagate it through all visual
b9dbd3
manifestations of The CentOS Project corporate visual identity. When
b9dbd3
we say that we could produce one new visual style every two years we
b9dbd3
really mean: to work two years long in order to propagate a new visual
b9dbd3
style to all visual manifestations of The CentOS Project corporate
b9dbd3
visual identity.
b9dbd3

b9dbd3

Obviously, in order to propagate one visual style to all different

b9dbd3
visual manifestations of The CentOS Project corporate visual identity,
b9dbd3
we need first to know which the visual manifestations are.  To define
b9dbd3
which visual manifestations are inside The CentOS Project corporate
b9dbd3
visual identity is one of the goals the CentOS Artwork Repository and
b9dbd3
this documentation manual are both aimed to satisfy.
b9dbd3

b9dbd3

Once we define which the visual manifestation are, it is possible to

b9dbd3
define how to produce them, and this way, organize the automation
b9dbd3
process. Such automation process is one of the goals of
b9dbd3
<tt>`centos-art.sh'</tt> script.
b9dbd3

b9dbd3

With the combination of both CentOS Artwork Repository and

b9dbd3
<tt>`centos-art.sh'</tt> scripts we define work lines where translators,
b9dbd3
programmers, and graphic designers work together to distribute and
b9dbd3
reduce the amount of time employed to produce The CentOS Project
b9dbd3
monolithic corporate identity.
b9dbd3

b9dbd3

From a monolithic corporate visual identity point of view, notice that

b9dbd3
we are producing a new visual style for the same theme (i.e.,
b9dbd3
Flame). It would be another flame design but still a flame
b9dbd3
design. This idea is very important to be aware of, because we are
b9dbd3
somehow "refreshing" the theme, not changing it at all. 
b9dbd3

b9dbd3

This way, as we are "refreshing" the theme, we still keep oursleves

b9dbd3
inside the monolithic conception we are trying to be attached to
b9dbd3
(i.e., one unique name, and one unique visual style for all visual
b9dbd3
manifestations).
b9dbd3

b9dbd3

Producing artistic motifs is a creative process that may consume long

b9dbd3
time, specially for people without experienced knowledge on graphic
b9dbd3
design land. Using "randomly generated" conception to produce
b9dbd3
artistic motifs could be, practically, a way for anyone to follow in
b9dbd3
order to produce maintainable artistic motifs in few steps. 
b9dbd3

b9dbd3

Due to the "randomly generated" nature of Flame filter, we find that

b9dbd3
Flame pattern is not always the same when we use Flame
b9dbd3
filter interface.
b9dbd3

b9dbd3

Using the same pattern design for each visual manifestation is

b9dbd3
essential in order to maintain the visual connection among all visual
b9dbd3
manifestations inside the same theme.  Occasionally, we may introduce
b9dbd3
pattern variations in opacity, size, or even position but never change
b9dbd3
the pattern design itself, nor the color information used by images
b9dbd3
considered part of the same theme.
b9dbd3

b9dbd3
Important

Important

b9dbd3
When we design background images, which are considered part of the
b9dbd3
same theme, it is essential to use the same design pattern always.
b9dbd3
This is what makes theme images to be visually connected among
b9dbd3
themeselves, and so, the reason we use to define the word "theme"
b9dbd3
as: a set of images visually connected among themeselves.
b9dbd3

aaf678
b9dbd3

In order for us to reproduce the same flame pattern always,

b9dbd3
Flame filter interface provides the <samp>`Save'</samp> and <samp>`Open'</samp>
b9dbd3
options. The <samp>`Save'</samp> option brings up a file save dialog that
b9dbd3
allows you to save the current Flame settings for the plug-in, so that
b9dbd3
you can recreate them later.  The <samp>`Open'</samp> option brings up a file
b9dbd3
selector that allows you to open a previously saved Flame settings
b9dbd3
file.
b9dbd3

b9dbd3

The Flame settings we used in our example are saved in the file:

2.26.3 Construction

ee1f37
ee1f37
b9dbd3
b9dbd3

2.26.3.1 Step 1: Set image size

ee1f37
b9dbd3

Create an empty image and fill the <samp>`Background'</samp> layer with black

b9dbd3
(000000) color. Image dimensions depend on the final
b9dbd3
destination you plan to use the image for. For the sake of our
b9dbd3
construction example we used an image of 640x480 pixels and 300 pixels
b9dbd3
per inch (ppi).
b9dbd3

ee1f37
b9dbd3
b9dbd3

2.26.3.2 Step 2: Add base color and pattern information

982d5c
b9dbd3

Create a new layer named <samp>`Base'</samp>, place it over <samp>`Background'</samp>

b9dbd3
layer and fill it with the base color (7800ff) you want to have
b9dbd3
your background image set in.  Add a mask to <samp>`Base'</samp> layer using
b9dbd3
radial gradient and blur it.  You may need to repeat this step more
b9dbd3
than once in order to achieve a confortable black radial degradation
b9dbd3
on the right side of your design.
b9dbd3

b9dbd3

Duplicate <samp>`Base'</samp> layer and name it <samp>`Paper'</samp>. Place

b9dbd3
<samp>`Paper'</samp> layer over <samp>`Base'</samp> layer. Remove content of
b9dbd3
<samp>`Paper'</samp> layer and fill it with <samp>`Paper (100x100)'</samp> pattern.
b9dbd3
Once you've done with black radial degradation, reduce the
b9dbd3
<samp>`Paper'</samp> layer opacity to 20%. 
b9dbd3

b9dbd3

Notice that when we duplicate one layer, the mask information related

b9dbd3
to layer is preserved from previous to next layer. This saves us some
b9dbd3
of the time required to produce different layers with the same mask
b9dbd3
information on them.
b9dbd3

b9dbd3

Duplicate <samp>`Paper'</samp> layer and rename it <samp>`Stripes'</samp>. Remove

b9dbd3
paper pattern from <samp>`Stripes'</samp> layer. Fill <samp>`Stripes'</samp> layer
b9dbd3
with <samp>`Stripes (48x48)'</samp> pattern and reduce the <samp>`Stripes'</samp>
b9dbd3
layer opacity to 15%.
b9dbd3

b9dbd3
b9dbd3

2.26.3.3 Step 3: Add flame motif

ee1f37
b9dbd3

Create a new layer named <samp>`Flame'</samp>. Set the foreground

b9dbd3
(003cff) and background (0084ff) colors to the gradient
b9dbd3
you want to build the flame motif. 
b9dbd3

b9dbd3

To build flame motif, use the flame filter (<samp>`Filters > Render >

b9dbd3
Nature > Flame...'</samp>) on <samp>`Flame'</samp> layer. We used a layer mask, with
b9dbd3
a radial gradient on it to control the boundaries of flame motif on
b9dbd3
<samp>`Flame'</samp> layer.
b9dbd3

b9dbd3

Duplicate <samp>`Flame'</samp> layer and rename it `Flame Blur'. Place `Flame

b9dbd3
Blur' below <samp>`Flame'</samp> layer. Apply Gussian blur filter
b9dbd3
(<samp>`Filters > Blur > Gussian Blur...'</samp>) until reaching the desiered
b9dbd3
effect.
b9dbd3

b9dbd3

The opacity value, in <samp>`Flame'</samp> layers, may vary from one image to

b9dbd3
another based on the place the image will be finally placed on.  For
b9dbd3
example, images used as desktop background have the <samp>`Flame'</samp> layer
b9dbd3
opacity set at 100% but <samp>`Flame Blur'</samp> is set to 70%.  However, you
b9dbd3
may find that background images used in anaconda progress slides have
b9dbd3
opacity reduced differently, in order to reduce brightness in a way
b9dbd3
that texts could look clean and readable over it.
b9dbd3

b9dbd3
b9dbd3
b9dbd3

2.26.3.4 Step 4: Add foreground color

b9dbd3
b9dbd3

Create a new layer named <samp>`Color'</samp>, place it on top of all visible

b9dbd3
layers and fill it with plain color (4c005a). Reduce
b9dbd3
<samp>`Color'</samp> layer opacity to 20%. You can use the <samp>`Color'</samp> layer
b9dbd3
to control the right side color information you want to produce the
b9dbd3
image for.
b9dbd3

b9dbd3

Duplicate <samp>`Flame'</samp> layer and create a new layer named

b9dbd3
<samp>`Color#1'</samp>. Place <samp>`Color#1'</samp> layer on top of layer named
b9dbd3
<samp>`Color'</samp>. Remove the mask information from <samp>`Color#1'</samp> layer
b9dbd3
and recreate a new one using an inverted alpha channel as reference.
b9dbd3
Remove <samp>`Color#1'</samp> layer content and fill it back with plain black
b9dbd3
(000000) color. Reduce <samp>`Color#1'</samp> opacity to 20%.  In this
b9dbd3
step we created a mask to protect the flame artistic motif from black
b9dbd3
color, so when we decrement or increment the opacity of layer, the
b9dbd3
flame artistic motif wouldn't be affected, just the environment
b9dbd3
suround it.
b9dbd3

b9dbd3

When you set color information, remember that the same artistic motif

b9dbd3
needs to be indexed to 14 and 16 colors, in order to produce Grub and
b9dbd3
Syslinux visual manifestations respectively. Using many different
b9dbd3
colors in the artistic motif may reduce the possibility of your design
b9dbd3
to fix all different situations in.  Likewise, using more colors in
b9dbd3
one design, and less colors in another design will reduce the
b9dbd3
connectivity among your designs, since color information is relevant
b9dbd3
to visual identity. 
b9dbd3

b9dbd3

When you propagate your artistic motif visual style to different

b9dbd3
visual manifestations of CentOS Project corporate visual identity, it
b9dbd3
is up to you to find out justice and compromise among all possible
b9dbd3
variables you may face.
