$ \bigcirc$Description


This fills the field boundary of a Shape issued from a tree (see flst_boundary). It is a list of 2-D points with integral coordinates. The last point is equal to the first one if the shape is closed. If the shape is open, the two extremal points are at the border of the image. The shape is followed in counterclockwise direction, so that the shape is on left hand side and the exterior on right hand side.
