Thank you for your answer! It's exactly what i need!
Unfortunatelly I can't build/run my code, because i haven't
cairo-quartz.h (or something like that) inside the cairo's include
folder. I've installed cairo via MacPorts. And included "cairo.h" in the
code, but the Xcode can't find cairo_quartz_surface_create_for_cg_context().
Then i've tried to configure the port with "sudo port edit cairo" and
put there --enable-quartz. No results.
How should i correctly install/configure cairo+quartz+xcode?
Sorry if my questions are studid.
p.s. i've added "header search paths" and "library search path" to the
Xcode project. So the xcode sees cairo_surface_t and so on correctly,
but not the cairo_quartz_surface_create_for_cg_context().
Thank you for Your help.
