Summarize:

Creates a new line layer according to geometries of the input layer. The attributes are copied to the line layer.

Usage:

•  The input layer must be polygon layer.

•  The output layer is line layer.

•  The names of all input layers must be unique.

•  In a polygon geometry, the outer boundary is always stored in a clockwise direction. If the polygon has a hole,

   the hole (or inner) boundary is always stored in a counterclockwise direction.
