Description

Fills the interior of input Splines with solid white. The exterior is filled with solid black.

Open splines are closed with a straight line from start to end. Intersections where the spline crosses itself are resolved by inverting the interior and exterior sides of the lines at those junctions.

IMPORTANT

It is not recommended to use this node on splines that are out of the [0 ,1] tile. The filling process is unreliable in that case.
