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


class NSGlyphGenerator : NSObject


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.


Obtaining a glyph generator

class var shared: NSGlyphGenerator

Returns a shared instance of NSGlyphGenerator.
