Monochrome art can be somewhat non-exciting. How do we get colors? From
colormaps and visuals.
A visual is a description of the color capabilities of a particular graphics
mode. A colormap is a table of available colors for a particular visual.
Color in GDK is represented by a GdkColor class which contains an RGB value
and a pixel. The red, green, and blue values are in the range 0 to 65535
(16-bit). Contents of the pixel field depend on the visual.
<?php
class GdkColor {
var $red;
var $green;
var $blue;
var $pixel;
}
?>
