<p>PROBLEM TO BE SOLVED: To systematically and efficiently operate each operation by dividing a picture, and allowing the functions of the enlargement, reduction, movement, and scroll of a picture to belong to a mouse index in each range. SOLUTION: A screen is divided into 9 ranges 3-11, and all the ranges 3-11 are rectangular and come into contact with each other. Those ranges 3-11 are mutually demarcated with a line 15. Then, when a mouse index 12 is present in one of the ranges 3, 5, 9, or 11, the enlargement or reduction of a picture 2 can be attained. When a mouse index 14 is present in the range 7, the movement of the picture 2 can be attained. When a mouse index 13 is present in either one of the ranges 4, 6, 8, or 10, the scroll of the picture 2 can be attained. In this case, at the time of dragging with the mouse index, a pixel at the lower side of the mouse index follows up the operation of the mouse index in the begging of the operation. At the time of movement, all the pixels which can be displayed are relatively moved to the mouse index.</p> |
