Description

EllipseSegmentSelect is a selection method that selects Segments in response to a mouse click in the graphics window when the Skeleton Selection toolbox is active and is set to “Segment” mode. It selects all Segments lying within a ellipse swept out by dragging the mouse, as shown in Figure 6.25. The ellipse is defined by the rectangle that bounds it. Click the mouse on one corner of the rectangle and drag to the diagonally opposite corner. Only Segments lying entirely within the ellipse will be selected.

skeleton is the Skeleton from which the Segments are to be selected.

points is a list of Point objects. The first point in the list is one corner of the rectangle bounding the ellipse, and the second point is the diagonally opposite corner. Any other points in the list will be ignored.

The shift and ctrl parameters govern how the current selection (i.e, the set of Segments defined by this operation) is merged with the previous selection (the Segments already selected) to form a new selection, as shown in Table 6.1. They indicate whether (1) or not (0) the shift and control keys were depressed during the mouse click that initiated this command.
