For k = 0 To pic1.ScaleHeight
          clr = GetPixel(pic1.hdc, i, k)
                If clr = vbGreen Then
                SetPixel pic3.hdc, i, k, vbWhite
        Else

Hi,
GetPixel() returns the combination of Red, Green and Blue. So the Color you are checking

clr = GetPixel(pic1.hdc, i, k)
If clr = vbGreen Then

This will check only Red is 0, Blue is 0 and Green is 255.
But you may need to separate the Color values.
Also u can use Point(X as Single, y as Single) to get the (x,y) Pixel Value instead of GetPixel().
