C#에서 이미지 크기를 조정하는 방법은 무엇입니까?

private async Task<string> CompressAndSaveImageAsync(Bitmap inputImage, int quality=50){
   string imageSavedPath = string.Empty;
   try{
      var jpgEncoder = await GetEncoderAsync(ImageFormat.Jpeg);
      var imageEncoder = Encoder.Quality;
      var imageEncoderParameters = new EncoderParameters(1);
      var imageEncoderParameter = new EncoderParameter(imageEncoder, quality);
      imageEncoderParameters.Param[0] = imageEncoderParameter;
      var userId = Regex.Replace(WindowsIdentity.GetCurrent().Name, @"[^0&minus;9a&minus;zA&minus;Z]+", "_");
      var currentDateTime = Regex.Replace(DateTimeOffset.Now.ToString().Split(&#39;+&#39;)[0].Trim(), @"   [^0&minus;9a&minus;zA&minus;Z]+", "_");
      var imageName = $"{userId}_{currentDateTime}.jpg";
      imageSavedPath = "C:\Users\K\Desktop\Questions\Images";
      inputImage.Save(imageSavedPath, jpgEncoder, imageEncoderParameters);
      inputImage.Dispose();
   }
   catch (Exception ex){
      throw
   }
   return imageSavedPath;
}
private async Task<ImageCodecInfo> GetEncoderAsync(ImageFormat format){
   ImageCodecInfo imageCodecInfo = null;
   try{
      var codecs = ImageCodecInfo.GetImageDecoders();
      foreach (var codec in codecs){
         if (codec.FormatID == format.Guid){
            imageCodecInfo = codec;
         }
      }
   }
   catch (Exception ex){
      throw
   }
   return imageCodecInfo;
}
