Save (spath); Return Json (new {id = "0", mess = string. Format ("{0}{1}/{2}", BaseUrl, "Images", filedata.filename), IW = image. Width, ih = image.            Height}); } catch (Exception ex) {return Json (new {id = "1", mess = ex.            Message}); }} public ActionResult Trycrop (string img, int x, int y, int w, int h) {var imgpath = im            G.split ('/'); Image image = Image.FromFile (Path.Combine (HttpContext.Server.MapPatH ("~"), "Images", Imgpath[imgpath.count ()-1]); Crop (Image, W, h, x, y).            Save (Path.Combine (HttpContext.Server.MapPath ("~"), "Res", User.Identity.Name + "portrait.jpg"));        Return redirecttoaction ("Example", "account"); } public string BaseUrl {get {return Request.Url.Scheme + "://" + Req Uest.

Setresolution (image. HorizontalResolution, image.            VerticalResolution); using (Graphics graphic = graphics.fromimage (BMP)) {graphic.
