Question

有没有办法打印wpf窗口的截屏？

我尝试了很多东西，但要么是A4尺寸太大，要么因为没有设置边距而裁剪掉了。这里是我试过的代码：

的Sample1：

private void btnPrintStanzbild_Click(object sender, RoutedEventArgs e)
    {
        Visual target = gRight;

        Rect bounds = VisualTreeHelper.GetDescendantBounds(target);

        RenderTargetBitmap renderTarget = new RenderTargetBitmap((Int32)bounds.Width, (Int32)bounds.Height, 96, 96, PixelFormats.Pbgra32);

        DrawingVisual visual = new DrawingVisual();

        using (DrawingContext context = visual.RenderOpen())
        {
            VisualBrush visualBrush = new VisualBrush(target);
            context.DrawRectangle(visualBrush, null, new Rect(new Point(), bounds.Size));
        }

        renderTarget.Render(visual);
        PngBitmapEncoder bitmapEncoder = new PngBitmapEncoder();

        BitmapImage bi = new BitmapImage();


        bitmapEncoder.Frames.Add(BitmapFrame.Create(renderTarget));
        using (MemoryStream stm = new MemoryStream())
        {
            bitmapEncoder.Save(stm);
            bi.BeginInit();
            bi.CacheOption = BitmapCacheOption.OnLoad;
            bi.StreamSource = stm;
            bi.EndInit();
        }



        var vis = new DrawingVisual();
        var dc = vis.RenderOpen();
        dc.DrawImage(bi, new Rect { Width = bi.Width, Height = bi.Height });
        dc.Close();

        var pdialog = new PrintDialog();
        if (pdialog.ShowDialog() == true)
        {
            var queue = pdialog.PrintQueue;


            var area = queue.GetPrintCapabilities(pdialog.PrintTicket)
                            .PageImageableArea;

            pdialog.PrintVisual(vis, "My Image");
        }
    }

样品2：

PrintDialog pdialog = new PrintDialog();
        if (pdialog.ShowDialog() == true)
        {
            var queue = pdialog.PrintQueue;


            var area = queue.GetPrintCapabilities(pdialog.PrintTicket)
                            .PageImageableArea;

            pdialog.PrintVisual(this, "My Image");
        }
