Detailed Description

The Glyph class represents a glyph in an PDF document. A glyph is an image representation of a character in a font face. This class provides access to many information about a glyph, e.g. its metrics and outline rendering. The unit of the metrics provided by this class is always in font unit. The actual size of the font unit is defined by Font::UnitsPerEM().
