RegionProtocol

public protocol RegionProtocol

The RegionProtocol protocol exposes the methods and properties of an underlying cairo_region_t instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Region. Alternatively, use RegionRef as a lighweight, unowned reference if you already have an instance you just want to use.
