hi
I want reduce the size of and image
I google it and find a solution which is
 
        void compress(Image img,string path){
            EncoderParameter qualityParam =
                new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 60);
            ImageCodecInfo jpegCodec = GetEncoderInfo("image/jpeg");
            EncoderParameters encoderParams = new EncoderParameters(1);
            encoderParams.Param[0] = qualityParam;
            
            img.Save("check1.jpg", jpegCodec, encoderParams);
        }
        private static ImageCodecInfo GetEncoderInfo(string mimeType)
        {
            // Get image codecs for all image formats 
            ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
 
            // Find the correct image codec 
            for (int i = 0; i < codecs.Length; i++)
                if (codecs[i].MimeType == mimeType)
                    return codecs[i];
            return null;

Solution 1

remove the
img.Save("check1.jpg", jpegCodec, encoderParams);
line and use the Image instance img to whatever you want. I guess you don't know how to use Image, but to get futher help on that front you'll need to tell us what you want to use it for. Display it in an UI (ASP.NET, Winforms, WPF)?

                new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 60);
            ImageCodecInfo jpegCodec = GetEncoderInfo("image/jpeg");
            EncoderParameters encoderParams = new EncoderParameters(1);
            encoderParams.Param[0] = qualityParam;
 
            img.Save(path, jpegCodec, encoderParams);
        }
        private static ImageCodecInfo GetEncoderInfo(string mimeType)
        {
            // Get image codecs for all image formats 
            ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
 
            // Find the correct image codec 
            for (int i = 0; i < codecs.Length; i++)
                if (codecs[i].MimeType == mimeType)
