# NSGlyphGenerator

An object that performs the initial, nominal glyph generation phase in the layout process.

## Declaration

```swift
class NSGlyphGenerator
```

## Overview

Overview The nominal glyph generation pass essentially generates one glyph per character; the typesetter may later make substitutions in the glyph stream, for example, changing an acute accent glyph followed by an “e” glyph into a single acute-accented “é” glyph. NSGlyphGenerator communicates via the NSGlyphStorage protocol. An example of a class that conforms to the protocol is NSLayoutManager.
