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 direc‐
tory 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.
