# NSFontTraitMask

Constants for isolating specific traits of a font.

## Declaration

```swift
struct NSFontTraitMask
```

## Overview

Overview NSFontManager categorizes fonts according to a small set of traits. You can convert fonts by adding and removing individual traits, and you can get a font with a specific combination of traits. These pairs of traits are mutually exclusive: condensedFontMask and  expandedFontMask boldFontMask and  unboldFontMask italicFontMask and  unitalicFontMask
