Invalid Parameter Used

Question

Dear All, I have created a function to resize an image and save it to the server. This is the code:- try { System.Drawing.Image NewImg; System.Drawing.Image.GetThumbnailImageAbort dummyCallBack = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback); NewImg = fullSizeImg.GetThumbnailImage(image_width, image_height, dummyCallBack, IntPtr.Zero); NewImg.Save(path + image_name); int x = image_width; int y = image_height; string image_path = path + "\\" + image_name; Image oImg = Image.FromFile(image_path); Bitmap bmp = new Bitmap(x,y); System.Drawing.Imaging.Encoder Enc = System.Drawing.Imaging.Encoder.Transformation; EncoderParameters EncParms = new EncoderParameters(1); EncoderParameter EncParm; Graphics gr = Graphics.FromImage(bmp); gr.CompositingQuality = CompositingQuality.HighQuality; gr.SmoothingMode = SmoothingMode.HighQuality; gr.InterpolationMode = InterpolationMode.HighQualityBicubic; gr.DrawImage(oImg, 0, 0, x, y); gr.Save(); EncParms.Param = new EncoderParameter[] { new EncoderParameter(Enc,(long)EncoderValue.CompressionLZW), new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L) }; ImageCodecInfo ici ; ici = GetProperEncoder(image_name); bmp.Save(image_path, ici, EncParms); oImg.Dispose(); bmp.Dispose(); } catch (Exception e) { Console.WriteLine("Caught: {0}",e.Message); } However I am getting an exception on this line :- bmp.Save(image_path, ici, EncParms); The exception is System.Object {System.ArgumentException} "Invalid Parameter Used" Can anybody help me please? Thanks for your help and time
