}Expand description
Determine and operate on how a LineString is
wound. This functionality, and our implementation is
based on CGAL’s Polygon_2::orientation.
Required Associated Types
Required Methods
fn winding_order(&self) -> Option<WindingOrder>
fn winding_order(&self) -> Option<WindingOrder>
Return the winding order of this object if it
contains at least three distinct coordinates, and
None otherwise.
Iterate over the points in a clockwise order
The object isn’t changed, and the points are returned either in order, or in reverse order, so that the resultant order makes it appear clockwise
Iterate over the points in a counter-clockwise order
The object isn’t changed, and the points are returned either in order, or in reverse order, so that the resultant order makes it appear counter-clockwise
fn make_cw_winding(&mut self)
fn make_cw_winding(&mut self)
Change this object’s points so they are in clockwise winding order
fn make_ccw_winding(&mut self)
fn make_ccw_winding(&mut self)
Change this line’s points so they are in counterclockwise winding order
Provided Methods
fn clone_to_winding_order(&self, winding_order: WindingOrder) -> Self where
Self: Sized + Clone,
fn clone_to_winding_order(&self, winding_order: WindingOrder) -> Self where
Self: Sized + Clone,
Return a clone of this object, but in the specified winding order
fn make_winding_order(&mut self, winding_order: WindingOrder)
fn make_winding_order(&mut self, winding_order: WindingOrder)
Change the winding order so that it is in this winding order
