Android 19*10的数组颜色按照中心点旋转10度

fun rotateColors(colors: Array<IntArray>, degrees: Float): Array<IntArray> {
    val newColors = Array(10) { IntArray(19) { Color.BLACK } }
    val centerX = 9f
    val centerY = 4.5f
    val radians = Math.toRadians(degrees.toDouble())
    val sin = Math.sin(radians)
    val cos = Math.cos(radians)
    for (y in 0 until 10) {
        for (x in 0 until 19) {
            val offsetX = x - centerX
            val offsetY = y - centerY
            val rotatedX = cos * offsetX - sin * offsetY + centerX
            val rotatedY = sin * offsetX + cos * offsetY + centerY
            val originalX = rotatedX.toInt()
            val originalY = rotatedY.toInt()
            if (originalX in 0 until 19 && originalY in 0 until 10) {
                newColors[y][x] = colors[originalY][originalX]
            }
        }
    }
    return newColors
