2.37.1 Goals

ee1f37
52772c

This section describes the steps we followed to construct the

52772c
Flame artistic motif. This section may be useful for anyone
52772c
interested in reproducing the Flame artistic motif, or in
52772c
creating new artistic motifs for The CentOS Project corporate visual
52772c
identity (see section The <tt>`trunk/Identity'</tt> Directory).
52772c

52772c
52772c
52772c

2.37.2 Description

52772c
52772c

The Flame artistic motif was built using the flame filter of

52772c
Gimp 2.2 in CentOS 5.5.
52772c

52772c

The flame filter of Gimp can produce stunning, randomly generated

52772c
fractal patterns. The flame filter of Gimp gives us a great oportunity
52772c
to reduce the time used to produce new artistic motifs, because of its
52772c
"randomly generated" nature. Once the artistic motif be created, it
52772c
is propagated through all visual manifestations of CentOS Project
52772c
corporate visual identity using the <tt>`centos-art.sh'</tt> script
52772c
(see section The <tt>`trunk/Scripts/Bash'</tt> Directory) inside the CentOS Artwork Repository.
52772c

52772c

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

52772c
could reuse the CentOS distribution major release schema.  I.e., we
52772c
could produce a new visual style, every two years, based on a new
52772c
"randomly generated" flame pattern, and publish the whole corporate
52772c
visual identity (i.e., distribution stuff, promotion stuff, websites
52772c
stuff, etc.) with the new major release of CentOS distribution all
52772c
together at once.
52772c

52772c

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

52772c
defined the artistic motif, we need to propagate it through all visual
52772c
manifestations of The CentOS Project corporate visual identity. When
52772c
we say that we could produce one new visual style every two years we
52772c
really mean: to work two years long in order to propagate a new visual
52772c
style to all visual manifestations of The CentOS Project corporate
52772c
visual identity.
52772c

52772c

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

52772c
visual manifestations of The CentOS Project corporate visual identity,
52772c
we need first to know which the visual manifestations are.  To define
52772c
which visual manifestations are inside The CentOS Project corporate
52772c
visual identity is one of the goals the CentOS Artwork Repository and
52772c
this documentation manual are both aimed to satisfy.
52772c

52772c

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

52772c
define how to produce them, and this way, organize the automation
52772c
process. Such automation process is one of the goals of
52772c
<tt>`centos-art.sh'</tt> script.
52772c

52772c

With the combination of both CentOS Artwork Repository and

52772c
<tt>`centos-art.sh'</tt> scripts we define work lines where translators,
52772c
programmers, and graphic designers work together to distribute and
52772c
reduce the amount of time employed to produce The CentOS Project
52772c
monolithic corporate identity.
52772c

52772c

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

52772c
we are producing a new visual style for the same theme (i.e.,
52772c
Flame). It would be another flame design but still a flame
52772c
design. This idea is very important to be aware of, because we are
52772c
somehow "refreshing" the theme, not changing it at all. 
52772c

52772c

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

52772c
inside the monolithic conception we are trying to be attached to
52772c
(i.e., one unique name, and one unique visual style for all visual
52772c
manifestations).
52772c

52772c

Producing artistic motifs is a creative process that may consume long

52772c
time, specially for people without experienced knowledge on graphic
52772c
design land. Using "randomly generated" conception to produce
52772c
artistic motifs could be, practically, a way for anyone to follow in
52772c
order to produce maintainable artistic motifs in few steps. 
52772c

52772c

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

52772c
Flame pattern is not always the same when we use Flame
52772c
filter interface.
52772c

52772c

Using the same pattern design for each visual manifestation is

52772c
essential in order to maintain the visual connection among all visual
52772c
manifestations inside the same theme.  Occasionally, we may introduce
52772c
pattern variations in opacity, size, or even position but never change
52772c
the pattern design itself, nor the color information used by images
52772c
considered part of the same theme.
52772c

52772c
Important

Important

52772c
When we design background images, which are considered part of the
52772c
same theme, it is essential to use the same design pattern always.
52772c
This is what makes theme images to be visually connected among
52772c
themeselves, and so, the reason we use to define the word "theme"
52772c
as: a set of images visually connected among themeselves.
52772c

52772c
52772c

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

52772c
Flame filter interface provides the <samp>`Save'</samp> and <samp>`Open'</samp>
52772c
options. The <samp>`Save'</samp> option brings up a file save dialog that
52772c
allows you to save the current Flame settings for the plug-in, so that
52772c
you can recreate them later.  The <samp>`Open'</samp> option brings up a file
52772c
selector that allows you to open a previously saved Flame settings
52772c
file.
52772c

52772c

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

52772c

52772c

2.37.3 Construction

ee1f37
632e8b
52772c
52772c

2.37.3.1 Step 1: Set image size

ee1f37
52772c

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

52772c
(000000) color. Image dimensions depend on the final
52772c
destination you plan to use the image for. For the sake of our
52772c
construction example we used an image of 640x480 pixels and 300 pixels
52772c
per inch (ppi).
52772c

ee1f37
52772c
52772c

2.37.3.2 Step 2: Add base color and pattern information

ee1f37
52772c

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

52772c
layer and fill it with the base color (7800ff) you want to have
52772c
your background image set in.  Add a mask to <samp>`Base'</samp> layer using
52772c
radial gradient and blur it.  You may need to repeat this step more
52772c
than once in order to achieve a confortable black radial degradation
52772c
on the right side of your design.
52772c

52772c

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

52772c
<samp>`Paper'</samp> layer over <samp>`Base'</samp> layer. Remove content of
52772c
<samp>`Paper'</samp> layer and fill it with <samp>`Paper (100x100)'</samp> pattern.
52772c
Once you've done with black radial degradation, reduce the
52772c
<samp>`Paper'</samp> layer opacity to 20%. 
52772c

52772c

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

52772c
to layer is preserved from previous to next layer. This saves us some
52772c
of the time required to produce different layers with the same mask
52772c
information on them.
632e8b

52772c

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

52772c
paper pattern from <samp>`Stripes'</samp> layer. Fill <samp>`Stripes'</samp> layer
52772c
with <samp>`Stripes (48x48)'</samp> pattern and reduce the <samp>`Stripes'</samp>
52772c
layer opacity to 15%.
52772c

52772c
52772c
52772c

2.37.3.3 Step 3: Add flame motif

ee1f37
52772c

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

52772c
(003cff) and background (0084ff) colors to the gradient
52772c
you want to build the flame motif. 
52772c

52772c

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

52772c
Nature > Flame...'</samp>) on <samp>`Flame'</samp> layer. We used a layer mask, with
52772c
a radial gradient on it to control the boundaries of flame motif on
52772c
<samp>`Flame'</samp> layer.
52772c

52772c

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

52772c
Blur' below <samp>`Flame'</samp> layer. Apply Gussian blur filter
52772c
(<samp>`Filters > Blur > Gussian Blur...'</samp>) until reaching the desiered
52772c
effect.
52772c

52772c

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

52772c
another based on the place the image will be finally placed on.  For
52772c
example, images used as desktop background have the <samp>`Flame'</samp> layer
52772c
opacity set at 100% but <samp>`Flame Blur'</samp> is set to 70%.  However, you
52772c
may find that background images used in anaconda progress slides have
52772c
opacity reduced differently, in order to reduce brightness in a way
52772c
that texts could look clean and readable over it.
52772c

52772c
52772c
52772c

2.37.3.4 Step 4: Add foreground color

52772c
52772c

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

52772c
layers and fill it with plain color (4c005a). Reduce
52772c
<samp>`Color'</samp> layer opacity to 20%. You can use the <samp>`Color'</samp> layer
52772c
to control the right side color information you want to produce the
52772c
image for.
52772c

52772c

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

52772c
<samp>`Color#1'</samp>. Place <samp>`Color#1'</samp> layer on top of layer named
52772c
<samp>`Color'</samp>. Remove the mask information from <samp>`Color#1'</samp> layer
52772c
and recreate a new one using an inverted alpha channel as reference.
52772c
Remove <samp>`Color#1'</samp> layer content and fill it back with plain black
52772c
(000000) color. Reduce <samp>`Color#1'</samp> opacity to 20%.  In this
52772c
step we created a mask to protect the flame artistic motif from black
52772c
color, so when we decrement or increment the opacity of layer, the
52772c
flame artistic motif wouldn't be affected, just the environment
52772c
suround it.
52772c

52772c

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

52772c
needs to be indexed to 14 and 16 colors, in order to produce Grub and
52772c
Syslinux visual manifestations respectively. Using many different
52772c
colors in the artistic motif may reduce the possibility of your design
52772c
to fix all different situations in.  Likewise, using more colors in
52772c
one design, and less colors in another design will reduce the
52772c
connectivity among your designs, since color information is relevant
52772c
to visual identity. 
52772c

52772c

When you propagate your artistic motif visual style to different

52772c
visual manifestations of CentOS Project corporate visual identity, it
52772c
is up to you to find out justice and compromise among all possible
52772c
variables you may face.
