Hi,

Maybe?

Dim bm As New Bitmap("C:\test.png")

If bm.PixelFormat = Imaging.PixelFormat.Format16bppGrayScale Then

Trace.WriteLine("black and white")

Else

Trace.WriteLine("Color")

End If

This will tell us if a picture is black and white, however, if the asnwer is
False, it still does not absolutley tell us that the picture is color.

The colour depth could be 32Million colours and the picture could still be
black and white !
