load-icon-image returns an image object which can be drawn to port using draw-image and which must be freed using free-image when no longer needed.

When id specifies a file and width and height are specified, then the most appropriate image is chosen from the icon file and is scaled accordingly. If width and height are nil the first image in the file is used at its natural size. width defaults to nil and height defaults to width .

Note: load-icon-image is defined only in LispWorks for Windows.
