How to get pixel correctly, when Windows Magnifier is on?

Question

Hi, I would like to know, if there's some way to get correctly pixel color, which is pointed by cursor, when Windows Magnifier is on?

This is code sample, which works perfectly whether magnifier is off:

public static Color GetColorAtPosition(int x, int y)
{
	var desk = PInvoke.GetDesktopWindow();
	var dc = PInvoke.GetWindowDC(desk);
	try
	{
	    var a = (int)PInvoke.GetPixel(dc, x, y).Value;
	    return Color.FromArgb(255, (byte)(a >> 0 & 0xff), (byte)(a >> 8 & 0xff), (byte)(a >> 16 & 0xff));
	}
	finally
	{
	    PInvoke.ReleaseDC(desk, dc);
	}
}

P.S. PInvoke was created using Microsoft.Windows.CsWin32

Hi @Jacob Mordon , Welcome to Microsoft Q&A,

Get the exact pixel color by taking a screenshot and locating the mouse position in the image. This method avoids the interference of the magnifying glass.

Here is a sample code:

using System.Drawing;

public static Color GetColorAtPosition(int x, int y)
{
    using (var bitmap = new Bitmap(1, 1))
    {
        using (var g = Graphics.FromImage(bitmap))
        {
            g.CopyFromScreen(x, y, 0, 0, new Size(1, 1));
        }
        return bitmap.GetPixel(0, 0);
    }
}

Best Regards,

Jiale
