Instance Method

calculateIntersections(for:)calculateIntersectionsForLayer:calculateIntersectionsForLayer_

Calculates the intersections between the guide and a layer’s outlines.

func calculateIntersections(for layer: GSLayer)
- (void) calculateIntersectionsForLayer:(GSLayer *) layer;
calculateIntersectionsForLayer_(layer: GSLayer)

Parameters

layer

The layer whose outlines to intersect.

Discussion

Components are decomposed for the calculation. The result replaces intersections. If the layer has no bounds or the guide does not cross its bounds, intersections is set to nil.
