A set of values that describe the manner in which the pixel values for a visual are converted into RGB values for display.
|Each pixel value indexes a grayscale value directly.
|Each pixel is an index into a color map that maps pixel values into grayscale values. The color map can be changed by an application.
|Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values.
|Each pixel is an index into a color map that maps pixel values into rgb values. The color map can be changed by an application.
|Each pixel value directly contains red, green, and blue components. The red_mask, green_mask, and blue_mask fields of the visual structure describe how the components are assembled into a pixel value.
|Each pixel value contains red, green, and blue components as for Gdk::TRUE_COLOR, but the components are mapped via a color table into the final output table instead of being converted directly.
