cairo_surface_t* gdk_window_create_similar_surface ( GdkWindow* window, cairo_content_t content, int width, int height )
Create a new surface that is as compatible as possible with the
window. For example the new surface will have the same
fallback resolution and font options as
window. Generally, the new
surface will also use the same backend as
window, unless that is
not possible for some reason. The type of the returned surface may
be examined with cairo_surface_get_type().
Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.)
Available since: 2.22
The content for the new surface.
Width of the new surface.
Height of the new surface.
A pointer to the newly allocated surface. The caller
owns the surface and should call
cairo_surface_destroy() when done
This function always returns a valid pointer, but it will return a
pointer to a “nil” surface if
other is already in an error state
or any other error occurs.
|The caller of the method takes ownership of the data, and is responsible for freeing it.|
