The critical concept necessary for understanding graphics and imaging on the Java platform is the idea of user space and device space because they will be used extensively in this and other sections of the book.
User space is the coordinate space in which the user operates. At instantiation, the origin of user space is at the top-left corner of the screen with the x coordinate increasing to the right and the y coordinate increasing downward.
