Загрузка индексированного растрового изображения в байтовый массив приводит к неправильным необработанным значениям - PullRequest

При работе с растровыми изображениями я обнаружил проблему при загрузке необработанных байтовых данных .bmpinto. Я работаю с серыми индексированными битовыми картами 8bpp Я написал этот код для проверки поведения.

  void TestBitmap()
    {
        var startBytes = new byte[256];
        for (int i = 0; i < startBytes.Length; i++)
        {
            startBytes[i] = (byte)i;
        }
        SaveRawBufferToBitmap(startBytes, "1 - PreLoad.bmp");

        var bitmap = new Bitmap("1 - PreLoad.bmp");
        if (File.Exists("Bitmap.txt"))
            File.Delete("Bitmap.txt");
        for (int i = 0; i < 16; i++)
        {
            for (int j = 0; j < 16; j++)
            {
                File.AppendAllText("Bitmap.txt", $"{bitmap.GetPixel(j, i)}{Environment.NewLine}");
            }
        }

        var bmpdata = bitmap.LockBits(new System.Drawing.Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, System.Drawing.Imaging.PixelFormat.Format8bppIndexed);
        int numbytes = bmpdata.Stride * bitmap.Height;
        byte[] bytes = new byte[numbytes];
        IntPtr ptr = bmpdata.Scan0;
        Marshal.Copy(ptr, bytes, 0, numbytes);
        bitmap.UnlockBits(bmpdata);

        if (File.Exists("Bytes.txt"))
            File.Delete("Bytes.txt");
        for (int i = 0; i < bytes.Length; i++)
        {
            File.AppendAllText("Bytes.txt", $"{bytes[i]} ");
        }

        SaveRawBufferToBitmap(bytes, "2 - PostLoad.bmp");
    }


    public static void SaveRawBufferToBitmap(byte[] buffer, string path)
    {
        WriteableBitmap imageWritable;
        var rect = new Int32Rect(0, 0, 16, 16);
        var imageRotated = new byte[256];

        if (File.Exists(path))
            File.Delete(path);

        imageWritable = new WriteableBitmap(16, 16, 96, 96, System.Windows.Media.PixelFormats.Gray8, null);
        imageWritable.WritePixels(rect, buffer, 16, 0);
        using (FileStream stream = new FileStream(path, FileMode.Create))
        {
            var encoder = new TiffBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(imageWritable));
            encoder.Save(stream);
            stream.Close();
        }
    }

Я создаю массив из 256 байтов в диапазоне от 0 до 255 значений. Затем я записываю растровое изображение 16x16 из этих необработанных данных, переходя от черного к белому. Затем я вновь открываю сохраненное растровое изображение и преобразовываю его в байтовый массив и сохраняю необработанные данные в виде текста. Наконец я сохраняю второе растровое изображение для проверки согласованности.

Я обнаружил, что на моем ПК с Windows 10 данные .txt в порядке, как и ожидалось. Bitmap.txt:
