Image compression using C#

Sometimes, we need to compress the image files while maintaining the image quality. This can be achieved by the following C# implementation.

Usage: zoomImage(path, zoom).Save(destImagePath);

        private Image zoomImage(string fileName, float zoom = 0.25f)   // set quality to 1-100, eg 50

        {

            Image img = Image.FromFile(fileName);

            Image zoomedImage = new Bitmap(Image.FromFile(fileName), Convert.ToInt32(img.Width * zoom), Convert.ToInt32(img.Height * zoom));

            int quality = 100;

            var myImageCodecInfo = ImageCodecInfo.GetImageEncoders().Where(encoder => encoder.MimeType == "image/jpeg").FirstOrDefault();

            var myEncoderParameters = new EncoderParameters(1);

            myEncoderParameters.Param[0] = new EncoderParameter(Encoder.Quality, quality);

            var stream = new MemoryStream();

            zoomedImage.Save(stream, myImageCodecInfo, myEncoderParameters);

            var newImage = Image.FromStream(stream);

            var g = Graphics.FromImage(newImage);

            g.InterpolationMode = InterpolationMode.Default;

            g.DrawImage(newImage, new Rectangle(Point.Empty, newImage.Size), 0, 0,

              newImage.Width, newImage.Height, GraphicsUnit.Pixel, new ImageAttributes());

            return newImage;

        }
