The Drawing.GetPixelColor() method seems to be extremely slow and, also, somewhat unhelpful. The following program shows that you can only get about 65 calls per second on a 1.7GHz Pentium M --- which implies it takes about 25 million instructions to execute! This strikes me as very wrong for an essentially simple graphics operation.

Not only that, but the result that it returns isn't what you might expect -- if I set the background to white, I'd expect the value it returns to be the same. Either that or we need a "CompareColors()" method to allow you to check if two colours have the same "handle" but are really equivalent.

Would any of the Phrogram developers care to comment? 

Program PixColor

    Method Main()

        ClearBackground(Colors.White)
        PrintLine("Working ...")
        Define startTime As Integer = TickCount()
        Define i As Integer
        Define p As Integer
        For i = 1 To 1000
            p = GetPixelColor(100, 100)
        Next
        Define endTime As Integer = TickCount()
        Define secs As Decimal = (endTime - startTime) * 0.001
        PrintLine("1000 iterations took " + secs + " seconds (" + (1000.0 / secs) + " per sec)")
        PrintLine("Pixel colour was " + p + ", white is " + Colors.White)

    End Method

End Program
