Classes

Font	`PangoXftFont` is an implementation of `PangoFcFont` using the Xft library for rendering. It is used in conjunction with `PangoXftFontMap`.
FontMap	`PangoXftFontMap` is an implementation of `PangoFcFontMap` suitable for the Xft library as the renderer. It is used in to create fonts of type `PangoXftFont`.
Renderer	`PangoXftRenderer` is a subclass of `PangoRenderer` used for rendering with Pango’s Xft backend. It can be used directly, or it can be further subclassed to modify exactly how drawing of individual elements occurs.

Callbacks

SubstituteFunc

Function type for doing final config tweaking on prepared FcPatterns.

Functions

get_context	Retrieves a `PangoContext` appropriate for rendering with Xft fonts on the given screen of the given display.
get_font_map	Returns the `PangoXftFontMap` for the given display and screen. The fontmap is owned by Pango and will be valid until the display is closed.
picture_render	Renders a `PangoGlyphString` onto an Xrender Picture object.
render	Renders a `PangoGlyphString` onto an XftDraw object wrapping an X drawable.
render_layout	Render a `PangoLayout` onto a `XftDraw`
render_layout_line	Render a `PangoLayoutLine` onto a `XftDraw`
render_transformed	Renders a `PangoGlyphString` onto a `XftDraw`, possibly transforming the layed-out coordinates through a transformation matrix. Note that the transformation matrix for `font` is not changed, so to produce correct rendering results, the `font` must have been loaded using a `PangoContext` with an identical transformation matrix to that passed in to this function.
set_default_substitute	Sets a function that will be called to do final configuration substitution on a `FcPattern` before it is used to load the font. This function can be used to do things like set hinting and antialiasing options.
shutdown_display	Release any resources that have been cached for the combination of `display` and `screen`. Note that when the X display is closed, resources are released automatically, without needing to call this function.
substitute_changed	Call this function any time the results of the default substitution function set with `pango_xft_set_default_substitute()` change. That is, if your substitution function will return different results for the same input pattern, you must call this function.
