The CairoFontType class

简介

CairoFontType class is an abstract final class that contains constants used to describe the type of a given CairoFontFace or CairoScaledFont. The font types are also known as "font backends" within cairo.

The type of a CairoFontFace is determined by the how it is created, an example would be the CairoToyFontFace::__construct(). The CairoFontFace type can be queried with CairoFontFace::getType() or cairo_font_face_get_type()

The various CairoFontFace functions can be used with a font face of any type.

The type of a CairoScaledFont is determined by the type of the CairoFontFace passed to CairoScaledFont::__construct() or cairo_scaled_font_create(). The scaled font type can be queried with CairoScaledFont::getType() or cairo_scaled_font_get_type().
