                        image = new Bitmap(image, newWidth, 256);
                        Console.WriteLine($"Конечное разрешение: {height},{width}");

                    case ConsoleKey.N:
                        break;
                    default:
                        Console.WriteLine("Неверная клавиша");
                        Console.WriteLine("Выход из программы");
                        Environment.Exit(1);
                        break;
                }
            }
        }
    }
}

In case ConsoleKey.Y, when initializing the bitmap class with a new photo resolution, the ArgumentException error

Answer 1

The problem is passing image in the Bitmap constructor . there is no Bitmap(Bitmap,Int32,Int32) constructor, there is Bitmap(Image,Int32,Int32) In theory, it should work like this:image = new Bitmap(image, newWidth, 256);

image = new Bitmap((System.Drawing.Image)image, newWidth, 256);
