Structure

CGFontRef

A set of character glyphs and layout information for drawing text.

Declaration

typedef struct CGFont CGFontRef;

Overview

A glyph can represent a single character (such as ‘b’), more than one character (such as the “fi” ligature), or a special character such as a space. Core Graphics retrieves the glyphs for the font from ATS (Apple Type Services) and paints the glyphs based on the relevant parameters of the current graphics state.

Core Graphics provides a limited, low-level interface for drawing text. For information on text-drawing functions, see CGContext. For full Unicode and text-layout support, use the services provided by TextKit).
