Instance Method

insertGlyph(_:atGlyphIndex:characterIndex:)

Inserts a single glyph into the glyph stream at the given index and maps it to the character at the given character index.

Declaration

func insertGlyph(_ glyph: NSGlyph, atGlyphIndex glyphIndex: Int, characterIndex charIndex: Int)

Parameters

glyph

The glyph to insert.

glyphIndex

The index at which to insert the glyph.

charIndex

The index of the character to which the glyph is mapped.

Discussion

If the glyph is mapped to several characters, charIndex should indicate the first character it’s mapped to.

This method is for use by the glyph-generation mechanism and doesn’t perform any invalidation or generation of the glyphs or layout. This method should be invoked only during glyph generation and typesetting, in almost all cases only by the glyph generator or typesetter. For example, a custom glyph generator or typesetter might invoke it.
