In your example you have two Clone methods. But as both have no parameters (only different return types), there is no method override being done. C# allows you to keep the IClonable.Clone method, however it requires you to place the name of interface before the method name. As interfaces are public and the method is explicitly declared with the name of the interface there is no need for a access modifier as it is public by design.
Use the LockBits method to lock an existing bitmap in system memory so that it can be changed programmatically. You can change the color of an image with the SetPixel method, although the LockBits method offers better performance for large-scale changes.
