rgb(1)rgb(1)NAMErgb - build the color name database
SYNOPSISrgb [ dbname ]
DESCRIPTIONrgb reads from standard input lines of the form:
red green blue name
where red / green / blue are decimal values between the range 0 to 255,
and name is a description of the color. rgb then builds a color name
database in dbm 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 /usr/openwin/lib/rgb.txt. rgb.txt is compiled into the
dbm files rgb.dir and rgb.pag. When the server first starts up, it
consults the contents of these files to build an internal representa‐
tion of their contents. This internal representation is consulted to
map color names to color values.
rgb uses the default color name database of /usr/open‐
win/lib/X11/rgb.txt.
OPTIONS
dbname Color name database.
EXAMPLES
example% rgb rgb < rgb.txt
example% cat /usr/openwin/lib/rgb.txt
FILES
/usr/openwin/lib/rgb.txt color name database source. Maps color
names to RBG color values.
/usr/openwin/lib/rgb.dir dbm file containing color name to RGB
mapping.
/usr/openwin/lib/rgb.pag dbm file containing the color name to RGB
mapping.
