cairoGetScaledFont {RGtk2}R Documentation

cairoGetScaledFont

Description

Gets the current scaled font for a Cairo.

Usage

cairoGetScaledFont(cr)

Arguments

cr [Cairo] a Cairo

Details

Since 1.4

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_t object).
