DeviceProtocol
public protocol DeviceProtocol
The DeviceProtocol
protocol exposes the methods and properties of an underlying cairo_device_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 Device
.
Alternatively, use DeviceRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
