Abstract
The present invention provides a method and apparatus for storing and rapidly yet recognizably displaying graphic data. Digital ink is sampled at a predetermined sampling frequency to derive a set of points representing the graphic data. This set of points is reduced in number in order to define an approximate yet recognizable form of the graphic data. The rapid rendering of the graphic data in its approximate form allows the user to glance through several or more fields of graphic data similar to the way in which one would flip through pages in a paper notebook. Reduction in the number of points also facilitates efficient storage of the graphic data.
