详细说明

Matrix4x4 类型提供了一种通过 4x4 矩阵对Item 应用变换的方法。

它允许仅通过一个4x4矩阵提供的变换，同时实现旋转、缩放、平移和剪切。

以下示例将一个矩形旋转 45 度（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)
    }
}
