Abstract
Abstract A method and system for creating a freeform drawing object having any desired combination of polygonal and freehand segments. In a preferred embodiment, at any time during creation of the freeform drawing object, a polygonal segment is created by releasing a mouse at a polygonal cursor start point and then depressing it at a polygonal segment end point, and a freehand segment is created by dragging the mouse from a freehand cursor start point to a freehand cursor end point. Interpretation of whether a depress-move-release sequence should be considered a drag is based on the amount of time the mouse button is held down before being released. Any combination of polygonal and freehand segments is thus provided until the freeform object is completed by double clicking the mouse or by clicking the mouse at a cursor location within a predetermined distance from an original cursor point. During the creation of a polygonal segment a polygonal cursor is displayed and a straight rubber band line is drawn from the starting to current cursor location. During the creation of a freehand segment a freehand cursor is displayed which differs in appearance from the polygonal cursor, and a solid line is drawn along the cursor path.
