The outline of this selection uses smooth curves to join a series of points.
Click on the B-Spline Selection tool on the Tools bar.
Click at the point where you want the selection to begin. Click at the next point. The two points will be joined by a curve. Proceed with the clicking as you move around the area to be selected. Try to keep the points close-in to the area to ensure the accuracy of the selection. Finally click on, or at least near, the start point.
To finish, just right-click. The start and finish points will automatically be joined to complete the selection.
