<p>PURPOSE:To perform the designation of an area with an easy operation, by setting an arbitrary point as an origin, calculating a distance between two points based on the coordinate data of arbitrary two points, and designating a rectangular area in which the distance is set as a diagonal line. CONSTITUTION:The designation of the origin is performed by moving a mouse M to the origin 18. Next, the designation of a start point is performed by mov ing the M to the start point 19, and furthermore, the designation of an end point is performed by moving the M to the end point 20. The coordinate data designated in such a way is sent to and processed at a g graphic processor from the M, and is transmitted as an area data. In such a way, the area of oblique line part enclosed with the start point 19, the end point 20, a point A21, and a point B22 is designated. In such a way, it is possible to select a coordinate freely and to designate the area with the easy operation.</p> |
