Description
Creates a new Cairo with all graphics state parameters set to
default values and with target as a target surface. The target
surface should be constructed with a backend-specific function such
as cairoImageSurfaceCreate (or any other
cairo_backendsurfaceCreate() variant).Value
Cairo] a newly allocated Cairo with a reference
count of 1.
This function never returns NULL. If memory cannot be
allocated, a special Cairo object will be returned on
which cairoStatus returns CAIRO_STATUS_NO_MEMORY.
You can use this object normally, but no drawing will
be done.
Details
This function references target, so you can immediately
call cairoSurfaceDestroy on it if you don't need to
maintain a separate reference to it.
