GDI and GDI+ difference

Is there any way in VB.NET to draw rounded rectangles and invert images?

Hi andrey. Probably not the best way to do it - but here is one way.

Private Sub InvertBitmap(g As Graphics, b as Bitmap)

    Dim x, y, red, green, blue As Int32

    For x = 0 To b.Width - 1
        For y = 0 To b.Height - 1
            red = 255 - b.GetPixel(x, y).R
            green = 255 - b.GetPixel(x, y).G
            blue = 255 - b.GetPixel(x, y).B
            b.SetPixel(i, j, Color.FromArgb(red, green, blue))
        Next
    Next

End Sub

Thank you very much, but I prefer to use old good InvertRect or InvertRgn.

There are so many features for each trifle in NET...
