public interface LineShapeInterface
extends SelectableShapeInterface

An interface for shapes based on a set of lines that we need to modify at point level instead of bounds of the shape. A simple straight line can be modified using the bounds of the shape or using one of its ends. If the line is horizontal or vertical the bounds widht or height is equal to zero and this generates problems to resize it. It is also more natural to change the line shape by moving one of its ends instead of resising its bounds.
