MatrixRef

public struct MatrixRef : MatrixProtocol

A PangoMatrix specifies a transformation between user-space and device coordinates.

The transformation is given by

x_device = x_user * matrix->xx + y_user * matrix->xy + matrix->x0;
y_device = x_user * matrix->yx + y_user * matrix->yy + matrix->y0;

The MatrixRef type acts as a lightweight Swift reference to an underlying PangoMatrix instance. It exposes methods that can operate on this data type through MatrixProtocol conformance. Use MatrixRef only as an unowned reference to an existing PangoMatrix instance.

  • ptr 
    Untyped pointer to the underlying `PangoMatrix` instance.

    For type-safe access, use the generated, typed pointer matrix_ptr property instead.
