Display is a machine architecture independent image processing and display program.
It can display an image on any workstation display running an X server. The image can be displayed as background image of any window. Display first determines the hardware capabilities of your workstation. If the number of unique colors in an image is less than or equal to the number the workstation can support, the image is displayed in an X window . Otherwise the number of colors in the image is first reduced to match the color resolution of the workstation before it is displayed.
