Type Alias

CGGlyph

An index into the internal glyph table of a font.

Declaration

typealias CGGlyph = CGFontIndex

Discussion

When drawing text, you typically specify a sequence of characters. However, Core Graphics also allows you to use CGGlyph values to specify glyphs. In either case, Core Graphics renders the text using font data provided by the Apple Type Services (ATS) framework.

You provide CGGlyph values to the functions showGlyphs(g:count:) and showGlyphsAtPoint(x:y:glyphs:count:). These functions display an array of glyphs at the current text position or at a position you specify, respectively.
