Asynchronous interfaces are method calls such as * getWidth(ImageObserver) and drawImage(img, x, y, ImageObserver) * which take an ImageObserver object as an argument.

The image which was being * tracked is passed in using the img argument. Various constants * are combined to form the infoflags argument which indicates what * information about the image is now available.
