# `GSPath primitiveRepresentationSecondaryPen:`

*Instance Method*

Paths tracing the same outline using primitive node types and connections.

## Declaration

```swift
func primitiveRepresentation(secondaryPen secondPen: (any GSPenProtocol & NSObjectProtocol)?) -> [GSPath]
```

```objc
- (NSArray<GSPath *> *) primitiveRepresentationSecondaryPen:(NSObject<GSPenProtocol> *) secondPen;
```

```python
primitiveRepresentationSecondaryPen_(secondPen: NSObject<GSPenProtocol>) -> list[GSPath]
```

## Parameters

- `secondPen` — A pen for secondary outline information.

## Discussion

The secondary pen receives secondary outline information while path components are decomposed.
