16 058b0118 2005-01-03 devnull .SH DESCRIPTION
17 058b0118 2005-01-03 devnull .I Colors
18 058b0118 2005-01-03 devnull presents a grid showing the colors in the current color map.
19 058b0118 2005-01-03 devnull If the display is true color,
20 058b0118 2005-01-03 devnull .I colors
21 058b0118 2005-01-03 devnull shows a grid of the RGBV color map
22 058b0118 2005-01-03 devnull (see
23 058b0118 2005-01-03 devnull .IR color (7)).
24 058b0118 2005-01-03 devnull .PP
25 058b0118 2005-01-03 devnull Clicking mouse button 1 over a color in the grid will display the map index for that color,
26 058b0118 2005-01-03 devnull its
27 058b0118 2005-01-03 devnull red, green, and blue components,
28 058b0118 2005-01-03 devnull and the 32-bit hexadecimal color value as defined in
29 058b0118 2005-01-03 devnull .IR allocimage (3).
30 058b0118 2005-01-03 devnull If the
31 058b0118 2005-01-03 devnull .B -x
32 058b0118 2005-01-03 devnull option is specified, the components will also be listed in hexadecimal.
33 058b0118 2005-01-03 devnull .PP
34 058b0118 2005-01-03 devnull The
35 058b0118 2005-01-03 devnull .B -r
36 058b0118 2005-01-03 devnull option instead shows, in the same form, a grey-scale ramp.
37 058b0118 2005-01-03 devnull .PP
38 058b0118 2005-01-03 devnull A menu on mouse button 3 contains a single entry, to exit the program.
39 058b0118 2005-01-03 devnull .PP
40 058b0118 2005-01-03 devnull On 8-bit color-mapped displays,
41 058b0118 2005-01-03 devnull .I getmap
42 058b0118 2005-01-03 devnull loads the display's color map (default
43 058b0118 2005-01-03 devnull .BR rgbv ).
44 058b0118 2005-01-03 devnull The named
45 058b0118 2005-01-03 devnull .I colormap
46 058b0118 2005-01-03 devnull can be a file in the current directory or in the standard repository
47 058b0118 2005-01-03 devnull .BR /lib/cmap .
48 058b0118 2005-01-03 devnull It can also be a string of the form
49 058b0118 2005-01-03 devnull .B gamma
50 058b0118 2005-01-03 devnull or
51 058b0118 2005-01-03 devnull .BI gamma N\f1 ,
52 058b0118 2005-01-03 devnull where
53 058b0118 2005-01-03 devnull .I N
54 058b0118 2005-01-03 devnull is a floating point value for the gamma, defining the contrast for a monochrome map.
55 058b0118 2005-01-03 devnull Similarly,
56 058b0118 2005-01-03 devnull .B rgamma
57 058b0118 2005-01-03 devnull and
58 058b0118 2005-01-03 devnull .BI rgamma N
59 058b0118 2005-01-03 devnull define a reverse-video monochrome map.
60 058b0118 2005-01-03 devnull Finally, the names
61 058b0118 2005-01-03 devnull .B screen
62 058b0118 2005-01-03 devnull or
63 058b0118 2005-01-03 devnull .B display
64 058b0118 2005-01-03 devnull or
65 058b0118 2005-01-03 devnull .B vga
66 058b0118 2005-01-03 devnull are taken as synonyms for the current color map stored in the display hardware.
