NAME
gnome-background-properties - customize your desktop background
SYNOPSIS

DESCRIPTION
The Background preferences tool allows you to customize the desktop background. The desktop background is the part of the desktop where
there are no interface graphical items, such as panels and windows. The desktop background is always beneath the other interface items.
You can customize the desktop background in the following ways:
o Select an image to display on the desktop background. The image is superimposed on the desktop background color. The desktop back-
ground color is visible if you select a transparent image or if the image does not cover the entire desktop background.
o Select a color for the desktop background. You can select a solid color, or create a gradient effect with two colors. A gradient
effect is a visual effect where one color blends gradually into another color.
