CTFontCollection

The CTFontCollection opaque type represents a font collection, that is, a group of font descriptors taken together as a single object.

Overview

Font collections provide the capabilities of font enumeration, access to global and custom font collections, and access to the font descriptors comprising the collection.

Topics

Creating Font Collections

func CTFontCollectionCreateFromAvailableFonts(CFDictionary?) -> CTFontCollection

Returns a new font collection containing all available fonts.

func CTFontCollectionCreateWithFontDescriptors(CFArray?, CFDictionary?) -> CTFontCollection

Returns a new font collection based on the given array of font descriptors.

func CTFontCollectionCreateCopyWithFontDescriptors(CTFontCollection, CFArray?, CFDictionary?) -> CTFontCollection

Returns a copy of the original collection augmented with the given new font descriptors.

Getting Font Descriptors

Getting the Type Identifier

func CTFontCollectionGetTypeID() -> CFTypeID

Returns the type identifier for Core Text font collection references.

Data Types

class CTFontCollection

A reference to a font collection.

class CTMutableFontCollection

A reference to a mutable font collection.

Constants

kCTFontCollectionRemoveDuplicatesOption

Opaque Types

CTFont

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.

CTFontDescriptor

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.

CTFrame

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.

CTFramesetter

The CTFramesetter opaque type is used to generate text frames. That is, CTFramesetter is an object factory for CTFrame objects.

CTGlyphInfo

The CTGlyphInfo opaque type enables you to override a font's specified mapping from Unicode to the glyph ID.

CTLine

The CTLine opaque type represents a line of text.

CTParagraphStyle

The CTParagraphStyle opaque type represents paragraph or ruler attributes in an attributed string.

CTRun

The CTRun opaque type represents a glyph run, which is a set of consecutive glyphs sharing the same attributes and direction.

CTRunDelegate

The CTRunDelegate 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.

CTTextTab

The CTTextTab opaque type represents a tab in a paragraph style, storing an alignment type and location.

CTTypesetter

The CTTypesetter opaque type represents a typesetter, which performs line layout.
