# startLineMarker

The line marker used at the start of an open shape path.

## Declaration

```swift
var startLineMarker: ShapeMarkup.LineMarker { get set }
```

## Discussion

Discussion Line markers are only visible on open paths. Use shape.supportsLineMarkers to check whether the current shape supports line markers. Closed shapes like .rectangle and .ellipse ignore this property. Default is .none.
