Abstract:
1. A processing apparatus for processing graphic data which displays a graphic formed by combining graphic elements, each graphic element being represented by a location coordinate which indicates the position to be located and configuration thereof, comprising: a calculating unit that calculates a range coordinate representing coordinates of vertexes of a four-cornered shape which circumscribes each graphic element; and a sorting unit that sorts, into separate attributes of the graphic elements, the location coordinates and the range coordinates of the graphic elements as the graphic element data for displaying the graphic elements which constitute the graphic data; a first comparing unit that compares number of first tables where the graphic element data for displaying graphic elements which constitute a first graphic data are sorted into separate attributes and number of second tables where the graphic element data for displaying graphic elements which constitute a second graphic data are sorted into separate attributes; a second comparing unit that compares, with respect to each corresponding attribute, number of the graphic elements represented by the graphic element data sorted in said first tables and number of the graphic elements represented by the graphic element data sorted in said second tables; a third comparing unit that compares with, respect to each corresponding attribute, the range coordinates included in the graphic element data sorted in said first tables and the range coordinates included in the graphic element sorted in said second tables; a determining unit that determines whether or not the graphic element data whose range coordinates match with each other are found in each of the tables, when it is judged that the range coordinates included in all graphic element data in all corresponding tables are identical; and a fourth comparing unit that compares the location coordinates of the graphic elements sorted in said first tables corresponding to the attribute of said table and the location coordinates of the graphic elements sorted in said second tables corresponding to the same, when it is judged that the graphic element data whose range coordinates match with each other are found in any table.
