<p>PURPOSE:To easily display an optional graphic by sampling the position of a mouse cursor between the start and end point of time of a graphic with a proper interval and generating/displaying a straight line between adjacent sampling points. CONSTITUTION:A mouse 2 is used, the position of a mouse cursor 33 on a display screen 31 is moved optionally to sample the position of the mouse cursor 33 at a proper sampling period, a straight line tying consecutive sampling points is generated by a subroutine program generating a straight line to display the straight line. In decreasing the sampling period, a curve corresponding to the mobile locus of the mouse 2 is displayed, and in sampling the 1st desired position of the mouse cursor 33 and then the 2nd desired position of the mouse cursor 33 next, the straight line tying the 1st and 2nd positions is displayed. Thus, an optional graphic is displayed immediately by the mouse.</p> |
