Generating a resized image with maximum image quality

Here's some code I use for generating a resized image with no Jpeg compression.

public MemoryStream GetResized(Bitmap originalImage, int width, int height)
    System.Drawing.Image outputImage;
    MemoryStream outputStream = new MemoryStream();

    //Get codecs
    ImageCodecInfo[] icf = ImageCodecInfo.GetImageEncoders();

    EncoderParameters encps = new EncoderParameters(1);
    EncoderParameter encp = new EncoderParameter(Encoder.Quality, (long)100);

    //Set quality
    encps.Param[0] = encp;

    outputImage = originalImage.GetThumbnailImage(width, height, ThumbNailCallback(), IntPtr.Zero);
    outputImage.Save(outputStream, icf[1], encps);

    return outputStream;
