# kCTStrokeWidthAttributeName

The stroke width.

## Declaration

```swift
let kCTStrokeWidthAttributeName: CFString
```

## Discussion

Discussion Value must be a CFNumber object. Default value is 0.0, or no stroke. This attribute, interpreted as a percentage of font point size, controls the text drawing mode: positive values effect drawing with stroke only; negative values are for stroke and fill. A typical value for outlined text is 3.0.
