Please check this code...

All option set in dialog except the width and height.
Where is my mistake?

  Dim MyPage As New NPdfExporter(NDrawingDocument1) With {
    .Layout = PagedLayout.FitToPages,
    .CompressContents = False,
    .PageRows = 1,
    .PageColumns = 1,
    .Resolution = 300,
    .ZoomPercent = 100,
    .PageSize = New NSizeF(842, 595)
    }
   MyPage.ShowDialog()

The width and height 0....
