# strokeBorder(_:lineWidth:antialiased:)

Returns a view that’s the result of filling an inner stroke of this view with the content you supply.

```
@export(implementation) nonisolated func strokeBorder<S>(_ content: S = .foreground, lineWidth: CGFloat = 1, antialiased: Bool = true) -> StrokeBorderShapeView<Self.Content, S, Self> where S : ShapeStyle
```

## Discussion

This is equivalent to insetting `self` by `lineWidth / 2` and stroking the
resulting shape with `lineWidth` as the line-width.
