Context

open class Context(pointer: <Error class: unknown class><<Error class: unknown class>>)

A PangoContext stores global information used to control the itemization process.

The information stored by PangoContext includes the fontmap used to look up fonts, and default values such as the default language, default gravity, or default font.

To obtain a PangoContext, use method@Pango.FontMap.create_context.
