Title:
GRAPHIC PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JPS60173679
Kind Code:
A
Abstract:
PURPOSE:To furnish a graphic processing system heat indicates only physical quantity (graphic that represents physical quantity) required by a user by designating the feature quantity of a graphic that represents the physical quantity and thereby indicating only a group of graphics that conforms to the designation. CONSTITUTION:A mechanism that decides visible/invisible by deciding the feature quantity of a defined graphic is proyided in terminal side of graphic. For instance, if it is a vector, information on the direction, dimension and area of existence, that is a feature quantity, is extracted by a feature extracting circuit 53, and given to a condition judging device 60 through a signal line 51. The condition deciding device 60 decides conformance of the condition of extraction preset to an extraction condition setting register 40 and the feature quantity extracted from a given graphic by a feature quantity extracting device 50, and the condition of extraction of 40 is given by a signal line 41, and feature quantity of 50 is given to 60 by the signal line 51. A deciding circuit 65 decides whether all of the three conditions 62-64 hold or not, and the result is given to a deciding circuit 67 through a signal line 66. The circuit 67 takes logical sum of the result of decision corresponding to each graphic, and the result is transferred to a gate circuit 70 through a signal line 61.
