How to repaint the IWpfTextView after changes?

[Denis535]

Hi!
I save the snapshot of the entire window but first I reset the scroll of my IWpfTextView.
But there is a problem, the scroll is reset after I saved the snapshot.
So I want to ask, can I force a IWpfTextView to repaint?
Does anyone know how to do this?

    private static void TakeSnapshot(BitmapEncoder encoder, IWpfTextView view) {
        ThreadHelper.ThrowIfNotOnUIThread();
        var element = GetRoot( view.VisualElement );
        {
            view.ViewportLeft = 0;
            view.DisplayTextLineContainingBufferPosition( new SnapshotPoint( view.TextSnapshot, 0 ), 0, ViewRelativePosition.Top );
            view.Caret.MoveTo( new SnapshotPoint( view.TextSnapshot, 0 ), PositionAffinity.Predecessor );
            TakeSnapshot2( encoder, element );
        }
        while (view.TextViewLines.LastVisibleLine.End.Position < view.TextSnapshot.Length) {
            view.ViewScroller.ScrollViewportVerticallyByPixels( -100 );
            TakeSnapshot2( encoder, element );
        }
    }
    private static void TakeSnapshot2(BitmapEncoder encoder, FrameworkElement element) {
        var renderTargetBitmap = new RenderTargetBitmap( (int) element.ActualWidth, (int) element.ActualHeight, 96, 96, PixelFormats.Pbgra32 );
        renderTargetBitmap.Render( element );
        encoder.Frames.Add( BitmapFrame.Create( renderTargetBitmap ) );
    }

P.S.
I want to make an extension to snapshot my documents into gif animation with smooth scrolling.

One can use:

View.VisualElement.UpdateLayout();
