WPF Draw Heart 2.0 edition of Happy New Year

2017 New Year's day has arrived, want to do a blessing language window, put on a painting heart program changed, into the following interface.

The next place to change, the first window has no title bar.

MainWindow.xaml

allowstransparency="True"MouseDoubleClick="Window_mousedoubleclick"WindowStyle="None"Background="#00FFFFFF"Loaded="window_loaded"Mousemove="Window_mousemove"Title="MainWindow"height=" the"Width=" the"

The style of the middle circle button

<style targettype="Button"x:key="ButtonStyle"> <setter property="Template"> <Setter.Value> <controltemplate targettype="Button"> <Grid> <ellipse width=" $"height=" $"> <Ellipse.Fill> <lineargradientbrus H startpoint="0,0"Endpoint="0,1"> <gradientstop offset="0"Color="Blue"/> <gradientstop offset="1"Color="LightBlue"/> </LinearGradientBrush> </ellipse. fill> </Ellipse> <ellipse width=" the"height=" the"> <Ellipse.Fill> <lineargradientbrus H startpoint="0,0"Endpoint="0,1"> <gradientstop offset="0"Color=" White"/> <gradientstop offset="1"Color="Transparent"/> </LinearGradientBrush> </ellipse. fill> </Ellipse> <contentcontrol Verticalalignme Nt="Center"Horizontalalignment="Center"Content="{TemplateBinding Content}"FontSize=" -"fontweight="Bold"Foreground="Red"/> </Grid> </ControlTemplate> </set ter. Value> </Setter> </Style>

Although there is no title bar, in order to allow the window to move freely

      Private void Window_mousemove (object  sender, MouseEventArgs e)        {            if (E.leftbutton = =  mousebuttonstate.pressed)            {                this. DragMove ();            }        }

Double-click the mouse to close the window

        privatevoid Window_mousedoubleclick (object  sender, MouseButtonEventArgs e)        {           this. Close ();        }

No longer use thread sleep to animate the creation of the heart, this time using a timer.

      Private DispatcherTimer timer = new DispatcherTimer ();//Create Timer Object public          MainWindow ()        {            InitializeComponent ();            Windowstartuplocation = Windowstartuplocation.centerscreen;            this.bendediction.Content = "2017 \ r \ n Happy New Year";            Timer. Tick + = new EventHandler (Timer_tick); Adds an event, timed to the event              timer. Interval = timespan.frommilliseconds (100);//Set Timer long              timer. Start ();        }        void Timer_tick (object sender, EventArgs e)        {            if (Itick < Maxstep)            {                createheartline (itick);            }            Else            {                timer. Stop ();            }            itick++;        }

The generation algorithm of the heart, basically unchanged, just the radius and position of the heart to adjust the next.

Private voidCreateheartline (intItick) {Centerpt= canvas_shape.width/4; Radius= Canvas_shape.width/6;  for(inti =0; i < Itick; i++) {System.Windows.Controls.Image img=NewSystem.Windows.Controls.Image (); Img. Source=NewBitmapImage (NewUri (@"image/"+2+". PNG", urikind.relative));//give the photo pathImg. Height = $; Img. Width= $; Img. Stretch=Stretch.fill; DoubleAngle =2* Math.pi/maxstep *i; //Peach-shaped Heart                Doublex = centerpt- -* (Math.sin (angle) * Math.sin (angle) * Math.sin (angle)) * -;//                Doubley = centerpt-( -* Math.Cos (angle)-5* Math.Cos (2* Angle)-2* Math.Cos (3* Angle)-Math.Cos (4* angle)) * -;//canvas.setleft (IMG, x);                Canvas.settop (img, y);            Canvas_Shape.Children.Add (IMG); }        }     

In order to add background music, MediaElement was used.

       private void Window_Loaded (object sender, RoutedEventArgs e)        {            me. Loadedbehavior = mediastate.manual;  Set to manually control              me. Unloadedbehavior = mediastate.manual;            String strpath = String. Format (@ "{0}\data\music\bk.mp3", System.Windows.Forms.Application.StartupPath);            Uri uri = new Uri (strpath, urikind.relative);            Me. Source = URI;            Me. IsHitTestVisible = true;            Me. mediaended + = new Routedeventhandler (me_mediaended);            Gd. Children.add (me);            Me. Play ();        }

To be able to loop playback

      Private void me_mediaended (object  sender, RoutedEventArgs e)        {            me. Stop ();            Me. Play ();        }
