How can I programmatically resize images? RRS feed

  • Question

  • I have images from AD at 96x95. Is there a way to programmatically resize these images to 175x175 without losing image quality? I have never done this before, and wondering if this is even possible and if so has anyone had success doing this. 

    Thank you so much for your help.

    Thank you for posting here.

    You could not resize image without lose quality. As I know, SmoothingMode.HighQuality is a better way to reduce the lose of quality.

      int newWidth = 175;
                int newHeight = 175;
                Image srcImage = Image.FromFile("1.jpg");
                Bitmap newImage = new Bitmap(newWidth, newHeight);
                using (Graphics gr = Graphics.FromImage(newImage))
                    gr.SmoothingMode = SmoothingMode.HighQuality;
                    gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
                    gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
                    gr.DrawImage(srcImage, new Rectangle(0, 0, newWidth, newHeight));
