enumerateCompositionUnits(_:supporting:extraHandles:secondaryPen:)enumerateCompositionUnits:supporting:extraHandles:secondaryPen:enumerateCompositionUnits_supporting_extraHandles_secondaryPen_

Calls the block such that the shapes of the group are divided into composition units ready for display.

func enumerateCompositionUnits(
    _ code: @escaping ([GSShape], [GSShape]?, [GSShape]?) -> Void,
    supporting supportedFeatures: GSDrawStackFeature,
    extraHandles: NSMutableArray?,
    secondaryPen secondPen: (any GSPenProtocol & NSObjectProtocol)?
)
- (void) enumerateCompositionUnits:(void (^)(NSArray<GSShape *> *shapes, NSArray<GSShape *> *subtractMasks, NSArray<GSShape *> *intersectMasks)) code
                        supporting:(GSDrawStackFeature) supportedFeatures
                      extraHandles:(NSMutableArray *) extraHandles
                      secondaryPen:(NSObject<GSPenProtocol> *) secondPen;
enumerateCompositionUnits_supporting_extraHandles_secondaryPen_(
    shapes: list[GSShape],
    subtractMasks: list[GSShape],
    intersectMasks: list[GSShape],
    code,
    supportedFeatures: GSDrawStackFeature,
    extraHandles: list,
    secondPen: NSObject<GSPenProtocol>

Discussion

  • Hidden shapes are skipped.

  • Mask shapes are skipped and instead provided as parameters to the block.
