    稳扎稳打Silverlight(7) - 2.0图形之Ellipse, Line, Path, Polygon, Polyline, Rectangle


    作者:webabcd


    介绍
    Silverlight 2.0 图形:
        Ellipse - 椭圆
        Line - 线
        Path - 一系列相互连接的直线和曲线
        Polygon - 多边形,闭合图形,起点与终点自动相连
        Polyline - 非闭合图形,一串连接起来的线,起点与终点不会自动相连
        Rectangle - 矩形

    示例
    1、Ellipse.xaml
    <UserControl x:Class="Silverlight20.Shape.Ellipse"
        xmlns
    ="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x
    ="http://schemas.microsoft.com/winfx/2006/xaml">
        
    <StackPanel HorizontalAlignment="Left">
            
            
    <!--椭圆-->
            
    <!--
            Width - 椭圆的宽
            Height - 椭圆的高
            Stroke - 边框
            StrokeThickness - 边框尺寸
            Fill - 填充
            
    -->
            
    <Ellipse Stroke="Red" Fill="Yellow" StrokeThickness="6" Width="100" Height="50"></Ellipse>
            
        
    </StackPanel>
    </UserControl>


    2、Line.xaml
    <UserControl x:Class="Silverlight20.Shape.Line"
        xmlns
    ="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

            Y1 - 起点的 Y 坐标
            X2 - 终点的 X 坐标
            Y2 - 终点的 Y 坐标
            注:
                Line无填充,也就是Line的Fill属性无效
                坐标以左上角为原点,原点右侧/下侧为正方向
            
    -->
            
    <Line X1="0" Y1="100" X2="200" Y2="300" Stroke="Black" StrokeThickness="6" />
