[README.Schema]

The schemata offered in the Options/Schema menu are
taken from from configurations files with a *.schema
pattern either located in $TDEDIR/share/apps/konsole
or ~/.trinity/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.
