Title: Graphic coordinate managing method
Inventor: ANEHA YUMIKO
IPC: G06F17/50
Filed: 1988-03-14
Abstract: PURPOSE:To reduce the amount of index data and to improve the efficiency of a retrieval processing by setting plural grid blocks with different grid intervals and shape, and making the data belong to the grid block at a preceding stage when a graphic which traverses the blocks exists. CONSTITUTION:The maximum and the minimum ranges are calculated from the graphics (A-D), and next, the highest-order range (1, 1) is bi-sected into an upper and a lower parts, which generate grid blocks b1(1, 1) and b2(2, 1). Next, the graphic extending over the blocks b1 and b2 is discriminated, and when no graphic exists, a pointer 20a is set at 0, and the highest-order range is bi-sected into a right and a left parts, which generate the grid blocks c1(1, 1) and c2(1, 2). Since the graphic B extending over the blocks c1 and c2 exists, (1) representing the existence of the graphic B is inserted to the (1, 1) of the pointer 20b of the block b1 at the one preceding stage, then, the B is set on an index 21. When the same processing is applied to the grid block with the minimum range, the number of data in the index 21 becomes equal to that of graphic data, then, the number of the index data can be reduced. Also, by designating a retrieval range, a double retrieval prevention processing is not required, thereby, the efficiency of the retrieval processing can be improved.
