NAME
getmap, colors – display color map
SYNOPSIS
colors
[
-rx
]
getmap
[
colormap
]
DESCRIPTION
Colors
presents a grid showing the colors in the current color map.
If the display is true color,
colors
shows a grid of the RGBV color map
(see
color(6)).
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
allocimage(2).
If the
-x
option is specified, the components will also be listed in hexadecimal.
The
-r
option instead shows, in the same form, a grey-scale ramp.
A menu on mouse button 3 contains a single entry, to exit the program.
On 8-bit color-mapped displays,
getmap
loads the display’s color map (default
rgbv).
The named
colormap
can be a file in the current directory or in the standard repository
/lib/cmap.
It can also be a string of the form
gamma
or
gammaN,
where
N
is a floating point value for the gamma, defining the contrast for a monochrome map.
Similarly,
rgamma
and
rgammaN
define a reverse-video monochrome map.
Finally, the names
screen
or
display
or
vga
are taken as synonyms for the current color map stored in the display hardware.
