Title: Selecting method for superposed graphic forms
Inventor: YAMAMOTO TETSUYA
IPC: G06F17/50
Filed: 1985-10-04
Abstract: PURPOSE:To select a necessary graphic form without using a selective mask based upon an attribution value by shifting a display position only by a minute distance corresponding to the attribution value of graphic information at the selection of the graphic information and selecting a graphic form on the basis of the shifted display.
