Classes

The following classes are available globally.

  • A FontFile object represents the file of a specific font format.

    Declaration

    Swift

    public class FontFile
    Show on GitHub

  • The Renderer class represents a generic glyph renderer. It can be used to generate glyph paths, measure their bounding boxes and draw them in a CGContext object.

    See more

    Declaration

    Swift

    public class Renderer
    Show on GitHub

  • The Typeface class specifies the typeface and intrinsic style of a font. This is used in the renderer, along with optionally Renderer settings like typeSize, slantAngle, scaleX, to specify how text appears when drawn (and measured).

    Declaration

    Swift

    public class Typeface

  • The TypefaceManager class provides management activities related to typefaces.

    Declaration

    Swift

    public class TypefaceManager

  • Represents a frame containing multiple lines of text. It is the output resulting from text-framing process performed by a typesetter.

    Declaration

    Swift

    public class ComposedFrame
    Show on GitHub

  • Represents a line of text consisting of an array of GlyphRun objects in visual order.

    Declaration

    Swift

    public class ComposedLine
    Show on GitHub

  • This class resolves text frames by using a typesetter object.

    Declaration

    Swift

    public class FrameResolver
    Show on GitHub

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

    See more

    Declaration

    Swift

    public class GlyphRun
    Show on GitHub

  • Represents a typesetter which performs text layout. It can be used to create lines, perform line breaking, and do other contextual analysis based on the characters in the string.

    Declaration

    Swift

    public class Typesetter
    Show on GitHub

  • The ShapingEngine class represents text shaping engine.

    See more

    Declaration

    Swift

    public class ShapingEngine
    Show on GitHub

  • A ShapingResult object is a container for the results of text shaping. It is generated by a ShapingEngine object to provide the information related to characters, their glyphs, offsets, and advances.

    Declaration

    Swift

    public class ShapingResult
    Show on GitHub

  • This class implements Unicode Bidirectional Algorithm available at http://www.unicode.org/reports/tr9.

    A BidiAlgorithm object provides information related to individual paragraphs in source string by applying rule P1. It can be used to create paragraph objects by explicitly specifying the paragraph level or deriving it from rules P2 and P3. Once a paragraph object is created, embedding levels of characters can be queried from it.

    Declaration

    Swift

    public class BidiAlgorithm
    Show on GitHub

  • A BidiLine object represents a single line processed with rules L1-L2 of Unicode Bidirectional Algorithm. Instead of reordering the characters as stated by rule L2, it allows to query and iterate over reordered level runs. The caller is responsible to reorder the characters manually, if required.

    Declaration

    Swift

    public class BidiLine
    Show on GitHub

  • A BidiParagraph object represents a single paragraph of text processed with rules X1-I2 of Unicode Bidirectional Algorithm. It contains the resolved embedding levels of all the characters of a paragraph and provides the facility to query them or iterate over their runs.

    Declaration

    Swift

    public class BidiParagraph

  • This class implements UAX #24 available at http://www.unicode.org/reports/tr24.
