fs28 NSCachedImageRep, a subclass of NSImageRep, defines an object that stores its source data as a rendered image in a window, typically a window that stays off-screen. The only data that'27s available for reproducing the image is the image itself. Thus an NSCachedImageRep differs from the other kinds of NSImageReps defined in the Application Kit, all of which can reproduce an image from the information originally used to draw it. Instances of this class are generally used indirectly, through an NSImage object.
