I have to re size an existing image and with proper width and height.
for now this is the code I have the code like this

Image resized = ResizeImageForFull(original, new Size(768, 1024));

//save the image to memory stream
MemoryStream memStream = new MemoryStream();
resized.Save(memStream, System.Drawing.Imaging.ImageFormat.Jpeg)


after getting the modified image it is saved to the memory stream. can any one help me to put that into a target folder to save it as a jpeg image.

public static Image ResizeImageForFull(Image image, Size size, bool preserveAspectRatio = true)
        {
            int newWidth=0;
            int newHeight=0;

            if (preserveAspectRatio)
            {
                newWidth = size.Width;
                newHeight = size.Height;
            }

            Image newImage = new Bitmap(newWidth, newHeight);
            using (Graphics graphicsHandle = Graphics.FromImage(newImage))
            {
                graphicsHandle.InterpolationMode = InterpolationMode.HighQualityBicubic;
                graphicsHandle.DrawImage(image, 0, 0, newWidth, newHeight);
            }

            return newImage;
        }
