  • 一起学Windows Phone7开发(十三.七 绘图控件)

          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。

    XAML

    <InkPresenter Grid.Row="1" Height="512" HorizontalAlignment="Left" Margin="24,65,0,0" Name="inkPresenter1" VerticalAlignment="Top" Width="444"  LostMouseCapture="inkPresenter1_LostMouseCapture" MouseLeftButtonDown="inkPresenter1_MouseLeftButtonDown" MouseMove="inkPresenter1_MouseMove" Background="White"/>

    代码:

     private void inkPresenter1_LostMouseCapture(object sender, MouseEventArgs e)

            {

                NewStroke = null;

            }

     

            private void inkPresenter1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)

            {

                inkPresenter1.CaptureMouse();

                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)

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

            }

     

    二.Path:路径控件通过Markup Syntax来绘制一系列的线条或通过Geometries来绘制形状,这个控件是图形控件中最复杂的。

    Geometries:

    <Path Grid.Row="1" 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>

     

    <Path Grid.Row="1" Height="428" HorizontalAlignment="Left" Margin="12,127,0,0" Name="path1" Stroke="Red" StrokeThickness="10" VerticalAlignment="Top" Width="456" Fill="Green">

                <Path.Data>

                    <GeometryGroup FillRule="EvenOdd">

                        <EllipseGeometry Center="200,200" RadiusX="100" RadiusY="150"/>

                        <RectangleGeometry Rect="100,200,300,200"/>

                    </GeometryGroup>

                </Path.Data>

            </Path>

     

    Mini-Language

    <Path Grid.Row="1" Height="428" HorizontalAlignment="Left" Margin="12,127,0,0" Name="path1" Stroke="Red" StrokeThickness="3" VerticalAlignment="Top" Width="456" Data="M 10,40 L 300,40 V 100 H 240 S 300,240 400,175"/>

    移动命令:

    M:绝对起始点

    m:相对前一点的起始点

    如:M 100,200

    直线命令:

    L/l:直线的结束点

    如:L100,200

    水平线命令:

    H/h x坐标

    如:H20

    垂线命令:

    V/v y坐标

    如:V100

    三次贝赛尔曲线命令:

    C/c:控制点坐标、控制点坐标、结束点坐标

    如:C 100,200 200,400 300,200

    二次贝赛尔曲线命令:

    Q/q:控制点坐标、结束点坐标

    如:Q100,200 300,200

    光滑三次贝赛尔曲线命令:

    S/s:控制点坐标、结束点坐标

    如:S 100,200 200,300

    光滑二次贝赛尔曲线命令:

    T/t:控制点、结束点

    如:T 100,200 200,300

    圆弧命令:

    A/a:弧大小(半径值)、弧角、优势弧标记(1大于等于180度,0小于180度)、正负弧标记、结束点

    如:A 5,5 0 0 0 10,10

    闭合命令:

    Z/z:将创建的曲线封闭。

     

    三.Ellipse:用来绘制圆形、椭圆形的绘图控件。

    <Ellipse Grid.Row="1" Height="200" HorizontalAlignment="Left" Margin="136,56,0,0" Name="ellipse1" Stroke="Red" StrokeThickness="2" VerticalAlignment="Top" Width="200" />

    <Ellipse Grid.Row="1" Height="312" HorizontalAlignment="Left" Margin="136,283,0,0" Name="ellipse2" Stroke="Red" StrokeThickness="2" VerticalAlignment="Top" Width="200" />

     

    四.Rectangle: 绘制矩形或圆角矩形的绘图控件,这个与border控件很相似,但是border是一个容器,可以包含其他控件,而rectangle只用于绘图,不能包含子控件。

    <Rectangle Grid.Row="1" Height="154" HorizontalAlignment="Left" Margin="119,80,0,0" Name="rectangle1" Stroke="Red" StrokeThickness="1" VerticalAlignment="Top" Width="213"  RadiusX="50" RadiusY="50"/>

    <Rectangle Grid.Row="1" Height="184" HorizontalAlignment="Left" Margin="126,370,0,0" Name="rectangle2" Stroke="Red" StrokeThickness="1" VerticalAlignment="Top" Width="214" />

    RadiusX/RadiusY:设置圆角大小。

     

    五.Line:  用于绘制两点间的直线。

    <Line X1="10" Y1="50" X2="350" Y2="50" Stroke="Red" StrokeThickness="5" Margin="36,144,23,324" Grid.Row="1" />

    <Line X1="200" Y1="10" X2="200" Y2="300" Stroke="Blue" StrokeThickness="5" Margin="36,144,23,147" Grid.Row="1" />

    六.Polygon:  多边形控件。绘制封闭图形。

    <Polygon Grid.Row="1" Height="249" HorizontalAlignment="Left" Margin="104,95,0,0" Name="polygon1" Stroke="Red" StrokeThickness="5" VerticalAlignment="Top" Width="336" Points="10,10 200,25 300,175 200,200" Fill="blue"/>

    Points:点数,控制边的数量。

     

    七.Polyline:多段线控件。与多边形控件相似,可以绘制封闭、开放多边形。

    <Polyline Grid.Row="1" Height="307" HorizontalAlignment="Left" Margin="36,131,0,0" Name="polyline1" Stroke="Red" StrokeThickness="15" VerticalAlignment="Top" Width="394" Points="50,25 0,100 100,200 150,250 270,150" />

     

    八.Glyphs:符号控件。用于绘制字母、符号、字符等。主要用来显示Unicode字符。因为需要加载字体库或从网上下载字体库,就会引起显示慢的问题。

    <Glyphs Grid.Row="1" HorizontalAlignment="Left" Margin="36,34,0,0" Name="glyphs1" VerticalAlignment="Top" Height="474" Width="407" 

    FontUri="msyhbd.ttf"

    FontRenderingEmSize="100"

    Fill="Red"

    StyleSimulations="BoldItalicSimulation"

    OriginX="20"

    OriginY="200"

    UnicodeString="中国" />

     FontUri:指定文字格式路径,也可以是Web URL

     FontRenderingEmSize:指定以绘图图面单位计量的字号(默认为 .96 英寸)。

    StyleSimulations:设置字体粗体、斜体字形。
