[Winodows Phone 7控件详解]绘图控件-1

Silverlight的绘图能力是有目共睹的，那Phone7上也一样不会差，以下就是其绘图控件。

一.InkPresenter:可以产生手写效果的控件。

 <InkPresenter MouseLeftButtonDown="inkPresenter1_MouseLeftButtonDown" MouseMove="inkPresenter1_MouseMove"  LostMouseCapture="inkPresenter1_LostMouseCapture" Height="493" HorizontalAlignment="Left" Margin="28,34,0,0" Name="inkPresenter1" VerticalAlignment="Top" Width="405" Background="Yellow"  />        

InkPresenter和InkCanvas不同，前者需要实现相关的事件来产生手写效果。

        private Stroke NewStroke;
        public InkPresenterPage()
        {
            InitializeComponent();
        }

        private void inkPresenter1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            inkPresenter1.CaptureMouse();
            StylusPointCollection sc = new StylusPointCollection();
            sc.Add(e.StylusDevice.GetStylusPoints(inkPresenter1 ));
            NewStroke = new Stroke();
            inkPresenter1.Strokes.Add(NewStroke);
        }

        private void inkPresenter1_MouseMove(object sender, MouseEventArgs e)
        {
            if (NewStroke != null)
            {
                NewStroke.StylusPoints.Add(e.StylusDevice.GetStylusPoints(inkPresenter1));
            }
        }

        private void inkPresenter1_LostMouseCapture(object sender, MouseEventArgs e)
        {
            NewStroke = null;
        }
