How to get pixel color by coordinates on Panel?

Question

C++ / C#

The point is in the title. We need to find the color of a pixel at certain coordinates on the PANEL and not on the pictureBox. I found there is one in winAPI, BitBlt which does it pretty badly. For example, I can pass coordinates to this function, and it will find the color of a pixel by other coordinates. I could bi-calibrate, but is it worth it? What bi were crutches. In general, if someone knows - write. Bitblt example

Answer 1

Get the panel image:

private static Image PanelToBitmap(Control pnl) {
    var bmp = new Bitmap(pnl.Width, pnl.Height);
    pnl.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
    return bmp;
}

Getting a pixel from an image:
Bitmap.GetPixel()
