How to increase the performance to a Crop method?

Hello fellows,
 
I am trying to make a crop method for a specific image with a specific coordinates. While searching around the Internet I found some examples. The fastest I found was this one and I made some fixes along the way. Can someone give me any suggestions to make it more faster?

private static Image CropImage(Image image,int xStart, int yStart, int height, int width)
        {
            try
            {
                if (image.Height < height)
                {
                    height = image.Height;
                }
                if (image.Width < width)
                {
                    width = image.Width;
                }
                var bmphoto = new Bitmap(width,height, PixelFormat.Format32bppPArgb);
                bmphoto.SetResolution(image.VerticalResolution, image.HorizontalResolution);
                var grPhoto = Graphics.FromImage(bmphoto);
                grPhoto.CompositingMode = CompositingMode.SourceOver;
                grPhoto.CompositingQuality = CompositingQuality.HighSpeed;
                grPhoto.InterpolationMode = InterpolationMode.Default;
                grPhoto.PixelOffsetMode = PixelOffsetMode.Half;
                grPhoto.SmoothingMode = SmoothingMode.None;
                grPhoto.DrawImage(image, new Rectangle(0, 0, width, height),xStart,yStart,width,height,GraphicsUnit.Pixel);
                var mm = new MemoryStream();
                bmphoto.Save(mm, ImageFormat.Jpeg);
                image.Dispose();
                bmphoto.Dispose();
                grPhoto.Dispose();
                var outimage = Image.FromStream(mm);
                return outimage;
            }
            catch (Exception ex)
            {
                throw new Exception("Error cropping image, the error was: " + ex.Message);
            }
        }
private void Button_Click(object sender, RoutedEventArgs e)
        {
            var stopwatch = new Stopwatch();
            var imagePath = @"11069.jpg";
            var resultImagePath = @" Woman Croped.jpg";
            stopwatch.Start();
            var resultImage = CropImage(new Bitmap(imagePath), 640,480,2400,1500); // ~177 ms
            resultImage.Save(resultImagePath);
            resultImage.Dispose();
            stopwatch.Stop();
            MessageBox.Show(stopwatch.Elapsed.Milliseconds + "ms");
        }
