CTFramesetter

Generate text frames.

Overview

CTFramesetter is an object factory for CTFrame objects.

The framesetter takes an attributed string object and a shape descriptor object and calls into the typesetter to create line objects that fill that shape. The output is a frame object containing an array of lines. The frame can then draw itself directly into the current graphic context.
