| cairoGetFontFace {RGtk2} | R Documentation |
Gets the current font face for a Cairo.
cairoGetFontFace(cr)
|
[Cairo] a Cairo |
[CairoFontFace] the current font face. To keep a reference to it, you must call
cairo_font_face_reference.
This function never returns NULL. If memory cannot be allocated, a
special "nil" CairoFontFace object will be returned on which
cairoFontFaceStatus 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
cairoSetFontFace with a nil font will trigger an error that
will shutdown the Cairo object).
