Claims

[Claims for Utility Model Registration] A display means, a cursor means for pointing out a point on the display means with a cursor, a coordinate detection means for detecting the coordinate value of the point pointed out by the cursor means, and a coordinate detection means for detecting the coordinate value of the point pointed out by the cursor means. a calculation means for calculating new coordinate values of the two points by calculating the coordinate values of the detected two points based on a predetermined magnification; and a calculation result of the calculation means or the coordinates of the two points detected by the coordinate detection means. rectangle drawing means for drawing a rectangle whose vertices at both ends of one diagonal line are either of the values, and a first rectangle previously displayed on the display means by the rectangle drawing means. rectangular fixed point display means for displaying handles, one of which is fixed in position by the cursor means; and pointing an arbitrary point within the first rectangular area using the cursor means and moving it to a predetermined position. 2 detected by the coordinate detection means at this time.
and memory means for holding the set of coordinate values, and the calculation means has two coordinate values held in the memory means.
The rectangle drawing means calculates new coordinate values by adding or multiplying the difference between the sets of coordinate values as the predetermined magnification, and draws a second rectangle with the handle specified by the rectangular fixed point display means as the origin. A graphic display device comprising means for transmitting two sets of coordinate values.
