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_t object).
