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. |
