Rotate an Image Based on the User Input

I had a requirement to Rotate an image (90, 180, 270 etc..) based on the user input, and also for me the input was stream of bytes. After finishing that task I thought of posting the same in C# corner. So for that what I did is, I took a simple image. Read all bytes in from a file on the disk. Create a memory stream from those bytes. Then I got the image from those memoryStream, and then I rotate the image using RotateFlipType, then I saved the file in some local path.

And now the problem has begun. When I start comparing all the properties for both the images i.e The original image and the rotated one, What I observed is the new modified rotated image has different CompressionValue.

Then I change the logic a bit to retain the same compression value.

I Create an Encoder object based on the GUID. I tried to get the compression type from the image.

And from that compression type got the compression value and set it back after rotating the image.

/// <summary>

/// 1: no compression

/// </summary>
/// <param name="image">image</param>
/// <returns>compression type</returns>
private static int GetCompressionType(Image image)
{
    int compressionTagIndex = Array.IndexOf(image.PropertyIdList, 0x103);
    PropertyItem compressionTag = image.PropertyItems[compressionTagIndex];
    return BitConverter.ToInt16(compressionTag.Value, 0);
}

/// <summary>
/// Get Compression Value based on Compression Type
/// </summary>
/// <param name="getCompressionType"></param>
/// <returns></returns>
private long GetCompressionValue(int getCompressionType)
{
    switch (getCompressionType)
    {
        case 1:
            return (long) EncoderValue.CompressionNone;

        case 2:
        case 3:
            return (long) EncoderValue.CompressionCCITT3;

        case 4:
            return (long) EncoderValue.CompressionCCITT4;

        case 5:
            return (long) EncoderValue.CompressionLZW;

        default:
            throw new NotImplementedException();
    }
}
