Hi

Set the scalemode of the picturebox to vbpixels.
There is 2 methods you can use:

1)
color = Picture1.Point(X, Y) 'returns a long representing the color

2)
Private Declare Function GetPixel Lib "gdi32" (ByVal hDC As Long, ByVal X As Long, ByVal Y As Long) As Long
color = GetPixel(Picture1.hDC, X, Y) 'returns a long representing the color


Method 2 is much faster than method 1, so use that if you have a large picture or many repetitions.
