GI.Pango.Structs.FontMetrics
Contents
Description
A #PangoFontMetrics structure holds the overall metric information for a font (possibly restricted to a script). The fields of this structure are private to implementations of a font backend. See the documentation of the corresponding getters for documentation of their meaning.
- newtype FontMetrics = FontMetrics (ForeignPtr FontMetrics)
