PURPOSE:To surely display a graphic on a display screen even when it belongs to memory space where no clipping processing is performed on part of the graphic originally by magnifying the area attribute or clipping area of each memory space by prescribed magnification, and executing the clipping processing based on the area attribute. CONSTITUTION:A clipping part 3 by area attribute magnifies the area attribute or the clipping area 13 of each memory space by the prescribed magnification, and checks whether or not a magnified area attribute 14 is superimposed on a set clipping area 13, or each area attribute is superimposed on a magnified clipping area 15, and extracts the memory space where clipping by the graphic is executed. In such a way, it is possible to prevent the memory space to which the graphic to be displayed belongs rounded off, and to prevent the omission of the display of the graphic that belongs to the memory space where no clipping processing is performed on part of the graphic originally occurring. |
