Detailed Description

The Matrix4x4 type provides a way to apply a transformation to an Item through a 4x4 matrix.

It allows for a combination of rotation, scale, translatation and shearing by using just one tranformation provided in a 4x4-matrix.

The following example rotates a Rectangle 45 degress (PI/4):

Rectangle {
    width: 100
    height: 100
    color: "red"

    transform: Matrix4x4 {
        property real a: Math.PI / 4
        matrix: Qt.matrix4x4(Math.cos(a), -Math.sin(a), 0, 0,
                             Math.sin(a),  Math.cos(a), 0, 0,
                             0,           0,            1, 0,
                             0,           0,            0, 1)
    }
}
