# render_loadConfig.sh -- This function defines CentOS brands

# pre-rendering configuration script. This function is used to produce

# CentOS brands translation files.

#

# The rendering process used to produce CentOS Brands translation

# files is a bit different to that commonly found in other artwork

# components inside CentOS Artwork Repository. Relevant differences

# are described below:

#

#  1) Translation files are not regular files, but symbolic links

#  pointing to the common template translation structure, inside the

#  translation template (`Tpl') directory.

#

#  2) Translation files are created using design templates as

#  reference. This script creates a translation structure where the

#  translation template (`Tpl') directory structure applies to each

#  single design template available.

#

#  For instance, if the translation template (`Tpl') directory

#  structure has 30 translation files and there are 20 design

#  templates, this script creates a translation structure of symbolic

#  links where the 30 translation files apply the 20 design templates

#  one by one, producing 600 images as result ---without counting

#  possible formats convenction that may happen during the

#  post-rendering actions---.

#

# Translation file names inside translation template (`Tpl') directory

# have special meaning:

#

#  1) Conventional file name (i.e. `blue.sed', `2c-a.sed', etc.): In

#  this case, replacements inside translation file are applied to

#  design template and the translation file name is used as final

#  image name. The final image is saved with same dimensions that its

#  design template has.

#

#  2) Numeric file name only (i.e. `300.sed', `200.sed', etc.): In

#  this case, replacements inside translation files are applied to the

#  design template, and the translation file name is used as final

#  image name. The final image is saved using an specific `width'

#  defined by the number part of the translation file name. The image

#  `height' is automatically scaled based on the previous `width'

#  definition to maintain the design template proportions. 

#

#  For instance, if your design template has 400x200 pixels of

#  dimension, and you apply a translation file named `300.sed' to it,

#  the final image you get as result will have 300x100 pixels of

#  dimension. 

#

#  The same is true if you use higher numbers like `1024.sed',

#  `2048.sed', etc. In these cases you have bigger images

#  proportionally.

#

#  As we are using scalable vectorial graphics as source, image size

#  definition starts to be a problem on very small generated images.

#  Bigger images have better definition. As it is bigger, more is the

#  image definition you have. But take care, too much definition for

#  an image that was not designed for such a big dimension can result

#  in something that looks different from what you expect. Just try,

#  look, and decide by yourself.

#

# Generally, translation files inside translation template (`Tpl')

# directory structure contain color replacements only. The color used

# as replacement pattern is black (#000000).

#

# Using CentOS Brand translation files rendering script, CentOS Brand

# designers can work freely and use this script to generate the

# translation files that renderImage needs, in order to produce CentOS

# Brand images in different dimensions and colors.
