Top left corner of image c#?

Question

C++ / C#

public void CreateSquare(int w, int h)
        {
            // нарезка изображения на квадраты типа bmp
            Rectangle REct = new Rectangle(X, Y, w, h);
            Bitmap bmpSquate = (Bitmap)bmp.Clone(REct,System.Drawing.Imaging.PixelFormat.DontCare);
        }

There is a source image of bmp type and it needs to be cut into squares. To do this, I clone the original image with a new rectangle area, giving its width and height as parameters accepted by the method. But how to get the coordinates of the top left corner of the original image? (The ones that are X and Y)?

Answer 1

Zero zero like what to get them

Answer 2

The coordinates start from the upper left corner, not from the middle.
