DesktopImage is a Cocoa sample application that demonstrates how to use the NSDesktopImages category of NSWorkspace. It shows how to use this set of APIs to set the desktop image for a given screen. An NSURL is used to describe that image.
An "options" dictionary controls how the image is presented: scaling factor, clipping state which affects the interpretation of Proportional scaling types, and fill color applied to any empty space around the image.
