[README.Schema]
The schemata offered in the Options/Schema menu are
taken from from configurations files with a *.schema
pattern either located in $KDEDIR/share/apps/konsole
or ~/.kde/share/apps/konsole.
Schemata allow to configure the color set that konsole
uses, together with some more information on rendition
processing.
Syntax
File
:: { [Line] ['#' Comment] '\n' }
Line
:: "title" Title
:: "image" Usage PathToPictureFile
:: "transparency" Fade Red Green Blue
:: "color" Slot Red Green Blue Transparent Bold
:: "rcolor" Slot Saturation Value Transparent Bold
:: "sysfg" Slot Transparent Bold
:: "sysbg" Slot Transparent Bold
Meaning
- Title is the text to appear in the Option/Schema menu.
It should be unique among all other schemata therefore.
- The "image" clause allows to place an image on the
konsole's background.
- Usage can be either
- "tile" - the image is tilewise replicated.
- "center" - the image is centered.
- "full" - the image is stretched to fit the window size.
- The Path of the picture can both be relative
(to kde wallpapers) or absolute.
When a schema uses a background image (or transparency)
one has to make at least one color slot transparent to
achive any visible effect. Please read below about the
"Transparent" field in color,sysbg,sysfg.
- The "transparency" clause picks and uses the background
of the desktop as if it where an image together with
a fade effect. This effect will fade the background
to the specified color.
The "Fade" is a real value between 0 and 1, indicating
the strength of the fade. A value of 0 will not change
the image, a value of 1 will make it the fade color
everywhere, and in between. This will make the "glas"
of the window be of the color given in the clause and
being more(1) or less(0) intransparent.
- The remaining clauses (color,sysbg,sysfg) are used
to setup konsoles rendition system.
To this end, konsole offers 20 color slots.
Slot Meaning
----- --------------------------
0 regular foreground color
1 regular background color
2-9 regular bgr color 0-7
10 intensive foreground color
11 intensive background color
12-19 intensive bgr color 0-7
The traditional meaning of the "bgr" color codes
has a bitwise interpretation of an additive three
primary color scheme inherited from early EGA
color terminals.
Color Bits Colors
----- ---- -------
0 000 Black
1 001 Red
2 010 Green
3 011 Yellow
4 100 Blue
5 101 Magenta
6 110 Cyan
7 111 White
One may or may not stick to this tradition.
Konsole allows to assign colors freely to slots.
The slots fall apart into two groups, regular
and intensive colors. The later are used when
BOLD rendition is used by the client.
Each of the groups have a default fore- and
background color and the said bgr colors.
Normal terminal processing will simply use
the default colors.
The color desired for a slot is indicated
in the Red Green Blue fields of the color
clause. Use the sysfg or the sysbg clause
to indicate the default fore and background
colors of the desktop.
To specify randomized color for a slot use
the clause rcolor. The two parameters to it
being Saturation - the amount of colour,
and Value, the darkness of the colour.
To use transparency/images and to simulate
the behavior of the xterm, one can supply
two additional tags to each slot:
- Transparent (0/1) meaning to show the
background picture, if any.
- Bold (0/1) to render characters bold.
If you know about the escape codes, you might have
noticed that intensive and bold rendition are sort
of confused. This is inherited by the xterm which
konsole is simulating.
One can use the colortest.sh script supplied
with the konsole source distribution to test
a schema.
The schema installed with konsole are more or
less demonstrations and not really beauty,
beside the Linux.schema, perhaps, which is
made after the VGA colors.
