Имя (Name)
mapscrn - load screen output mapping table
Синопсис (Synopsis)
mapscrn [-V] [-v] [-o map.orig] mapfile
Описание (Description)
The mapscrn command is obsolete - its function is now built-in
into setfont. However, for backwards compatibility it is still
available as a separate command.
The mapscrn command loads a user defined output character mapping
table into the console driver. The console driver may be later
put into use user-defined mapping table mode by outputting a
special escape sequence to the console device. This sequence is
<esc>(K for the G0 character set and <esc>)K for the G1 character
set. When the -o option is given, the old map is saved in
map.orig.
USE
There are two kinds of mapping tables: direct-to-font tables,
that give a font position for each user byte value, and user-to-
unicode tables that give a unicode value for each user byte. The
corresponding glyph is now found using the unicode index of the
font. The command
mapscrn trivial
sets up a one-to-one direct-to-font table where user bytes
directly address the font. This is useful for fonts that are in
the same order as the character set one uses. A command like
mapscrn 8859-2
sets up a user-to-unicode table that assumes that the user uses
ISO 8859-2.
Входной формат (Input format)
The mapscrn command can read the map in either of two formats:
1. 256 or 512 bytes binary data
2. two-column text file
Format (1) is a direct image of the translation table. The
256-bytes tables are direct-to-font, the 512-bytes tables are
user-to-unicode tables. Format (2) is used to fill the table as
follows: cell with offset mentioned in the first column is filled
with the value mentioned in the second column. When values
larger than 255 occur, or values are written using the U+xxxx
notation, the table is assumed to be a user-to-unicode table,
otherwise it is a direct-to-font table.
Values in the file may be specified in one of several formats:
1. Decimal: String of decimal digits not starting with '0'
2. Octal: String of octal digits beginning with '0'.
3. Hexadecimal: String of hexadecimal digits preceded by "0x".
4. Unicode: String of four hexadecimal digits preceded by "U+".
5. Character: Single character enclosed in single quotes. (And
the binary value is used.) Note that blank, comma, tab character
and '#' cannot be specified with this format.
6. UTF-8 Character: Single (possibly multi-byte) UTF-8 character,
enclosed in single quotes.
Note that control characters (with codes < 32) cannot be re-
mapped with mapscrn because they have special meaning for the
driver.
