A map of colors that relates a specific value to a color. The colors are added to the maps data component.
The color options in a graphics system, arranged by index number. Typically, the system has a default colormap. The index of colors in the colormap can be reallocated, however, depending on the application.
A color lookup table that stores a set of RGB values. Applications index into the colormap to get the values to drive the red, blue, and green guns of an RGB monitor.
a color lookup table, where every entry specifes a color by a red, green and blue value in the RGB color model
a device-independent mapping between pixel values and colors displayed on the screen
an association between pixel values and colors
an object that contains the mapping between the color values stored in memory and the RGB values that are used to display color values
A colormap is a portable mechanism allowing pixel values to be mapped to RGB colors for display. In GTK+, the colormap is stored in a GdkColormap structure. More than one colormap may be installed at any given time, allowing the windows associated with those maps to display with true colors. The system colormap in most cases is a limited resource that should be conserved by selecting RGB values from the predefined color database, i.e. rgb.txt.
Another name for a palette; that is, a table of RGB color values (usually no more than 256) that is referenced by index in the main part of the image.
A mapping of pixel values to RGB color values. Use by color index windows.
The range of colors that can be used for display. It is the same as palette but colormap is the term used in the X Window System. A colormap is a list of red, green, and blue values. The values are referenced by an index into the list: entry 0 might be pink, entry 1 might be blue, entry 2 might be black, and so forth. X image data does not contain the actual color information but it does contain the index. This is either to reduce the amount of information contained in the image or because a display cannot handle true color. An 8 bits/pixel image can use 256 colors (28) and a 4 bits/pixel image can use 16 colors (24). A 24 bits/pixel image is true color and does not use a colormap.
an ordered set of colorcells, which is used to perform a function on a set of input values.
