Abstract
A figure data display method and system in which the contents to be stored and constituting data are stored in the form of figure data divided into a plurality of partial areas, a file information table is prepared which registers therein figure area information, along with volume information of the figure data, in the sequence of serial numbers allocated to the partial areas dependent on their positions, and those partial areas, which are necessary for display of the figure data, are searched within a range of the registered serial numbers. By preparing the figure data represented in the compressed form by taking relative values between the coordinate values of respective features points in the figure data, or by retrieving file names in a manner involving direct searching the figure data from a storage medium, operation from the step of reading the figure data to the step of displaying the same can be speeded up. High-speed infinite scrolling can also be achieved by setting an adjacent area based on the above retrieval when the predetermined area to be displayed is exceeded upon scrolling of the display area, and then deleting the unnecessary area.
