.SH DESCRIPTION
|
||
|
|
.I Colors
|
||
|
|
presents a grid showing the colors in the current color map.
|
||
|
|
If the display is true color,
|
||
|
|
.I colors
|
||
|
|
shows a grid of the RGBV color map
|
||
|
|
(see
|
||
|
|
.IR color (6)).
|
||
|
|
.PP
|
||
|
|
Clicking mouse button 1 over a color in the grid will display the map index for that color,
|
||
|
|
its
|
||
|
|
red, green, and blue components,
|
||
|
|
and the 32-bit hexadecimal color value as defined in
|
||
|
|
.IR allocimage (2).
|
||
|
|
If the
|
||
|
|
.B -x
|
||
|
|
option is specified, the components will also be listed in hexadecimal.
|
||
|
|
.PP
|
||
|
|
The
|
||
|
|
.B -r
|
||
|
|
option instead shows, in the same form, a grey-scale ramp.
|
||
|
|
.PP
|
||
|
|
A menu on mouse button 3 contains a single entry, to exit the program.
|
||
|
|
.PP
|
||
|
|
On 8-bit color-mapped displays,
|
||
|
|
.I getmap
|
||
|
|
loads the display's color map (default
|
||
|
|
.BR rgbv ).
|
||
|
|
The named
|
||
|
|
.I colormap
|
||
|
|
can be a file in the current directory or in the standard repository
|
||
|
|
.BR /lib/cmap .
|
||
|
|
It can also be a string of the form
|
||
|
|
.B gamma
|
||
|
|
or
|
||
|
|
.BI gamma N\f1 ,
|
||
|
|
where
|
||
|
|
.I N
|
||
|
|
is a floating point value for the gamma, defining the contrast for a monochrome map.
|
||
|
|
Similarly,
|
||
|
|
.B rgamma
|
||
|
|
and
|
||
|
|
.BI rgamma N
|
||
|
|
define a reverse-video monochrome map.
|
||
|
|
Finally, the names
|
||
|
|
.B screen
|
||
|
|
or
|
||
|
|
.B display
|
||
|
|
or
|
||
|
|
.B vga
|
||
|
|
are taken as synonyms for the current color map stored in the display hardware.
