CTRun

Declaration

class CTRun

Overview

A glyph run is a set of consecutive glyphs sharing the same attributes and direction.

The typesetter creates glyph runs as it produces lines from character strings, attributes, and font objects. That is, a line is constructed of one or more glyphs runs. Glyph runs can draw themselves into a graphic context, if desired, although most users have no need to interact directly with glyph runs.
