I want save all UserControl as image, at the same time, I need to show a animation in order to make the UI better for users.
This is MainWindow:

private void Button1_click(object sender, RoutedEventArgs e)
{
Thread t = new Thread(new ThreadStart(() => {
Dispatcher.BeginInvoke(new Action(() => {
AnimationView w = new AnimationView();
w.Show(); })); }));
t.Start();
foreach (UserControl UC in UserControl)
{
String fileName = UC.Name;
String filePath = "D:\ScreenShot";
SaveView(view, fileName, filePath);
}
}
public static void SaveView(UserControl view, string fileName, string destFolder)
{
Rect bounds = VisualTreeHelper.GetDescendantBounds(view);
int width = (int)view.RenderSize.Width;
int height = (int)view.RenderSize.Height;
if (width == 0 || height == 0)
{
width = 1920;
height = 1080;
}
RenderTargetBitmap rtb = new RenderTargetBitmap(width, height, 96, 96, PixelFormats.Pbgra32);
DrawingVisual dv = new DrawingVisual();
using (DrawingContext ctx = dv.RenderOpen())
{
Size size = new Size(500, 500);
if (bounds.Size.IsEmpty == false)
{
if (bounds.Size.Height > 100)
{
size = new Size(bounds.Size.Width, bounds.Size.Height - 100);
}
else
size = new Size(bounds.Size.Width, bounds.Size.Height);
}
VisualBrush vb = new VisualBrush(view);
ctx.DrawRectangle(vb, new Pen(Brushes.Blue, 2), new Rect(new Point(0, 100), size));
ctx.DrawText(text, new Point(0, 20));
ctx.Close();
}
// rtb.Render(view);
rtb.Render(dv);
try
{
PngBitmapEncoder jpgEncoder = new PngBitmapEncoder();
jpgEncoder.Frames.Add(BitmapFrame.Create(rtb));
Byte[] _imageArray;
using (MemoryStream outputStream = new MemoryStream())
{
jpgEncoder.Save(outputStream);
_imageArray = outputStream.ToArray();
}
//Try Find Save Path, if doesn't exists, create it.
if (Directory.Exists(destFolder) == false)
Directory.CreateDirectory(destFolder);
FileStream fileStream = new FileStream(Path.Combine(destFolder, fileName), FileMode.Create, FileAccess.ReadWrite);
fileStream.Write(_imageArray, 0, _imageArray.Length);
jpgEncoder.Save(fileStream);
fileStream.Close();
}
catch (Exception e)
{
Log4Net.Instance.Info(System.Reflection.MethodInfo.GetCurrentMethod().ToString());
Log4Net.Instance.Info("Exception Generate Screenshot: " + fileName);
Log4Net.Instance.Info(e.StackTrace.ToString());
Debug.WriteLine(e.ToString());
}
}), DispatcherPriority.Loaded);
}I hope I can get your help.
Many thanks in advance.
