.SH DESCRIPTION
|
|
|
|
|
.B rgb
|
|
|
|
|
reads from standard input lines of the form:
|
|
|
|
|
.PP
|
|
|
|
|
.nf
|
|
|
|
|
.I

.PP
|
|
|
|
|
where
|
|
|
|
|
.I red
|
|
|
|
|
/
|
|
|
|
|
.I green
|
|
|
|
|
/
|
|
|
|
|
.I blue
|
|
|
|
|
are decimal values between the range 0 to 255, and
|
|
|
|
|
.I name
|
|
|
|
|
is a description of the color.
|
|
|
|
|
.B rgb
|
|
|
|
|
then builds a color name database in
|
|
|
|
|
.B __RGB_DB_TYPE__
|
|
|
|
|
format. The color name database provides a mapping between ASCII color
|
|
|
|
|
names and RGB color values. It is useful for increasing the
|
|
|
|
|
portability of color programs. The input source for the database is
|
|
|
|
|
in \fI__RGB_DB__.txt\fP. \fIrgb.txt\fP
|
|
|
|
|
is compiled into the __RGB_DB_TYPE__ files
|
|
|
|
|
.IR "__RGB_DB_FILES__" .
|
|
|
|
|
When the server first starts up, it consults the contents of these
|
|
|
|
|
files to build an internal representation of their contents. This
|
|
|
|
|
internal representation is consulted to map color names to color
|
|
|
|
|
values.
|
|
|
|
|
.PP
|
|
|
|
|
.B rgb
|
|
|
|
|
uses the default color name database of \fI__RGB_DB__.txt\fP.
