Abstract
A graphic processing method and apparatus allows the operator to easily draw a curve with any curvature in any section of a graphic on the display screen of a computer. A frame appears when selecting a subject graphic to be transformed by operating a mouse. The frame has an operating member for size change, an operating member for movement, operating members for rotation, and an operating member for movement of the center. Each of the rotation operating members has a frame and a subject graphic rotation operating member, a frame rotation operating member, or a subject graphic rotation member. By selecting any one of the operating members, the subject graphic and frame rotate together, or only the frame or subject graphic rotates. The ratio for enlargement or reduction can be changed in accordance with the direction of the subject graphic by rotating only the frame or subject graphic and moving the transformation center according to necessity before changing the size. Therefore, it is possible to draw a curve with any curvature in any section of a graphic.
