EdgeClippingLayer

Given a set of clipping instructions encoded as a set of intersections between input edges, EdgeClippingLayer determines which graph edges correspond to clipped portions of input edges and removes them. It assembles the remaining edges into a new S2Builder::Graph and passes the result to the given output layer for assembly.

class EdgeClippingLayer : Layer {

this(Layer[] layers, byte[]* input_dimensions, InputEdgeCrossings* input_crossings);

GraphOptions graphOptions();

void build(Graph g, S2Error error);

string toString();

}
