You should post in iOS Question forum.

You can use Canvas.DrawView to draw the WebView content to an ImageView and then get the bitmap.

Private Sub Application_Start (Nav As NavigationController)
   NavControl = Nav
   Page1.Initialize("Page1")
   NavControl.ShowPage(Page1)
   Page1.RootPanel.LoadLayout("1")
   WebView1.LoadUrl("http://www.google.com")
End Sub


Sub WebView1_PageFinished (Success As Boolean, Url As String)
   Dim cvs As Canvas
   cvs.Initialize(ImageView1)
   Dim dest As Rect
   dest.Initialize(0, 0, ImageView1.Width, ImageView1.Height)
   cvs.DrawView(WebView1, dest)
   cvs.Refresh
End Sub
