Abstract

PURPOSE:To shorten arithmetic processing time by attaching vector data on the connecting point of graphics and moving and connecting the graphics when the graphics with directivity are connected. CONSTITUTION:When the connection processing of the connecting point PB1 of the graphic B to the connecting point PA2 of the graphic A is performed in the connection of the graphic A and the graphic B with directivity, the vector data VA2, VB1 are attached on those connecting points, respectively. A connection processing operation is performed by reading in the vector data VA2, VB1 and finding an angle to rotate the graphic A and travel distance by instructing the graphic to be connected i.e. the graphic to be moved and the position of the connecting point, and the connecting position of the graphic to be connected. A rotational angle goes to the angle formed by a minus component between the vector data VA2 and the vector data VB1. The travel processing of the graphic A is performed based on a calculated value, and the connection of the graphic A to the graphic B is performed.
