MatrixProtocol

public protocol MatrixProtocol

The MatrixProtocol protocol exposes the methods and properties of an underlying cairo_matrix_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 Matrix. Alternatively, use MatrixRef as a lighweight, unowned reference if you already have an instance you just want to use.
