Hi friend Use below code to preserve your image quality System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(thumbWidth ( int )thumbHeight); //- Create a System.Drawing.Graphics object from the Bitmap which we will use to draw the high quality scaled image System.Drawing.Graphics gr = System.Drawing.Graphics.FromImage(bitmap); //- Set the System.Drawing.Graphics object property SmoothingMode to HighQuality gr.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality; //- Set the System.Drawing.Graphics object property CompositingQuality to HighQuality gr.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; //- Set the System.Drawing.Graphics object property InterpolationMode to High gr.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High; //- Draw the original image into the target Graphics object scaling to the desired width and height System.Drawing.Rectangle rectDestination = new System.Drawing.Rectangle(0 0 thumbWidth ( int )thumbHeight); //Set Image codec of JPEG type the index of JPEG codec is 1 System.Drawing.Imaging.ImageCodecInfo codec = System.Drawing.Imaging.ImageCodecInfo.GetImageEncoders()[1]; //Set the parameters for defining the quality of the thumbnail... here it is set to 100% System.Drawing.Imaging.EncoderParameters eParams = new System.Drawing.Imaging.EncoderParameters(1); eParams.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality 100L); gr.DrawImage(image rectDestination 0 0 srcWidth srcHeight System.Drawing.GraphicsUnit.Pixel); Hope this helps you. Thanks
