The CTFramesetter opaque type is used to generate text frames. That is, CTFramesetter is an object factory for CTFrame objects.
Framework
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.
func CTFramesetterCreates an immutable framesetter object from an attributed string.
func CTFramesetterCreates an immutable frame using a framesetter.
func CTFramesetterReturns the typesetter object being used by the framesetter.
func CTFramesetterDetermines the frame size needed for a string range.
func CTFramesetterReturns the Core Foundation type identifier of the framesetter object.
class CTFramesetterA reference to a Core Foundation framesetter object.
The CTFont opaque type represents a Core Text font object. Font objects represent fonts to an application, providing access to characteristics of the font, such as point size, transform matrix, and other attributes. Fonts provide assistance in laying out glyphs relative to one another and are used to establish the current font when drawing in a graphics context.
The CTFontCollection opaque type represents a font collection, that is, a group of font descriptors taken together as a single object.
The CTFontDescriptor opaque type represents a font descriptor, that is, a dictionary of attributes (such as name, point size, and variation) that can completely specify a font.
The CTFrame opaque type represents a frame containing multiple lines of text. The frame object is the output resulting from the text-framing process performed by a framesetter object.
The CTGlyphInfo opaque type enables you to override a font's specified mapping from Unicode to the glyph ID.
The CTLine opaque type represents a line of text.
The CTParagraphStyle opaque type represents paragraph or ruler attributes in an attributed string.
The CTRun opaque type represents a glyph run, which is a set of consecutive glyphs sharing the same attributes and direction.
The CTRun opaque type represents a run delegate, which is assigned to a run (attribute range) to control typographic traits such glyph ascent, glyph descent, and glyph width.
The CTTextTab opaque type represents a tab in a paragraph style, storing an alignment type and location.
The CTTypesetter opaque type represents a typesetter, which performs line layout.
