WP7 开发（六） WP7控件开发（三）-绘图控件 地图控件

-InkPresenter:产生手写效果

示例代码：

Stroke newStroke;

private void inkPresenter1_LostMouseCapture(object sender, MouseEventArgs e)

{

newStroke = null;//失去焦点时销毁上一次的Stroke

}

private void inkPresenter1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)

{

inkPresenter1.CaptureMouse();//开始捕获鼠标移动路径

StylusPointCollection spc = new StylusPointCollection();

spc.Add(e.StylusDevice.GetStylusPoints(inkPresenter1));

newStroke = new Stroke();

this.inkPresenter1.Strokes.Add(newStroke);

}

private void inkPresenter1_MouseMove(object sender, MouseEventArgs e)

{

if (newStroke != null)

{

//记录鼠标在inkPresenter1上的移动的点

newStroke.StylusPoints.Add(e.StylusDevice.GetStylusPoints(inkPresenter1));

}

}

-Path：通过Markup Syntax来绘制一系列的线条，通过Geometries来绘制形状

示例:

<Path Height="428" HorizontalAlignment="Left"

Margin="12,127,0,0" Name="path1" Stroke="Red" StrokeThickness="10" VerticalAlignment="Top" Width="456" Fill="Green">

<Path.Data>

<EllipseGeometry Center="200,200" RadiusX="100" RadiusY="30"/>

</Path.Data>

</Path>

-Ellipse：绘制圆形或椭圆形

-Rectangle：绘制矩形

-Line：绘制两点间的连线

-Polygon：绘制封闭多边形

-Polyline：绘制封闭、开发多边形

-Glyphs：绘制字母、符号、字符等，主要用来显示Unicode字符，需要加载字体库从网上下载字体库，对于 使用不多的情况使用，否则会消耗系统的资源

-Map控件：在使用时，首先要申请授权验证密钥 显示模式设置有Road、Arial

-显示缩放按钮：ZoomBarVisibility属性

-显示比例尺：ScaleVisibility属性

-加标记：用到Pushpin类

//为地图加标记

Pushpin pin = new Pushpin();

pin.Location = new GeoCoordinate(30.3441333,120.342155132);

pin.Width = 200;

pin.Height = 200;

pin.Content = "济南";

pin.Background = new SolidColorBrush(Colors.Red);

mymap.Children.Add(pin);

-绘制多变型区域：用到MapPolygon类 实例化 设置Locations属性即可

//在地图上绘制多边形

MapPolygon polygon = new MapPolygon();

polygon.Fill = new SolidColorBrush(Colors.Red);

polygon.Stroke = new SolidColorBrush(Colors.Yellow);

polygon.StrokeThickness = 5;

polygon.Opacity = 0.7;

polygon.Locations = new LocationCollection()

{

new GeoCoordinate(30,120),

new GeoCoordinate(30,130),

new GeoCoordinate(30,160),

new GeoCoordinate(30,140)

};

mymap.Children.Add(polygon);

-绘制多边线：用到MapPolyline 实例化 设置Stroke属性和Locatatoins

//在地图上绘制多边线

MapPolyline polyline = new MapPolyline();

polyline.Stroke = new SolidColorBrush(Colors.Red);

polyline.StrokeThickness = 5;

polyline.Opacity = 0.5;

polyline.Locations = new LocationCollection()

{

new GeoCoordinate(30.3424242,120.3432444),

new GeoCoordinate(30.3424242,120.3432444)

};

mymap.Children.Add(polyline);

-在地图上添加图片

//在地图上添加图片

Image image = new Image();

image.Width = 100;

image.Height = 100;

image.Source = new BitmapImage(new Uri("Images/Pic1.jpg",UriKind.Relative));

MapLayer imagelayer = new MapLayer();

imagelayer.AddChild(image,new GeoCoordinate(30,120),PositionOrigin.BottomLeft);

mymap.Children.Add(imagelayer);
