Value

[CairoScaledFont] the current scaled font. To keep a reference to it, This function never returns NULL. If memory cannot be allocated, a special "nil" CairoScaledFont object will be returned on which cairoScaledFontStatus returns CAIRO_STATUS_NO_MEMORY. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling cairoSetScaledFont with a nil font will trigger an error that will shutdown the Cairo object).
