using System.Drawing;

void SaveSurface(string filename, Surface surface, int width, int height) {
   SurfaceDescription desc = surface.SurfaceDescription;
   using (Bitmap bitmap = new Bitmap(width, height)) {
     using (Graphics graphics = Graphics.FromImage(bitmap) {
       IntPtr hdc = graphics.GetHdc();
       try {
         surface.DrawToDc(hdc, new Rectangle(0, 0, width, height),
           new Rectangle(0, 0, desc.Width, desc.Height));
       }
       finally {
         graphics.ReleaseDc(hdc);
       }
     }
     bitmap.Save(filename);
   }
}

void LoadSurface(string filename, Surface surface) {
   // similar
}

Surface LoadSurface(string filename, SurfaceDescription desc) {
   // use the constructor that takes a string parameter
}
