从short []创建位图

Question

public void CreateMaps()
{
    var GridWidth = GridSizeX;
    var GridHeight = GridSizeY;
    int stride = GridWidth * 3 * 2;
    byte[] bluegrid = new byte[GridHeight * stride];
    for (int i = 0, j = 0; i < GridWidth * GridHeight; i++ , j+=6)
    {
        bluegrid[j] = (byte)(SelectedItem.BlueGrid[i] >> 8);
        bluegrid[j + 1] = (byte)(SelectedItem.BlueGrid[i] >> 8);
        bluegrid[j + 2] = (byte)(SelectedItem.BlueGrid[i] >> 8);
        bluegrid[j + 3] = (byte)(SelectedItem.BlueGrid[i] & 255);
        bluegrid[j + 4] = (byte)(SelectedItem.BlueGrid[i] & 255);
        bluegrid[j + 5] = (byte)(SelectedItem.BlueGrid[i] & 255);
    }

    JetColorMapBlueGrid = BitmapSource.Create(
                GridWidth,
                GridHeight,
                96.0,
                96.0,
                PixelFormats.Bgr24,
                null,
                bluegrid,
                stride
                );
}

这是我的功能，但它正在工作，我认为我正在裁剪我阵列的一部分 你能看一下将SelectedItem.BlueGrid []转换为 byte [] 的短数组，其大小为（GridSizeX，GridSizeY）的逻辑吗？
