将普通文字转成路径(Path)的方法 (WPF,Silverlight,SVG)

在WPF中使用

public String GetTextPath(String word,String fontFamily,int fontSizE)
{
            Typeface typeface = new Typeface(new FontFamily(fontFamily),FontStyles.Normal,FontWeights.Normal,FontStretches.Normal); 
            return GetTextPath(word,typeface,fontSizE);
}
public String GetTextPath(String word,Typeface typeface,int fontSizE)
{
            Formatted@R_566_3801@ = new FormattedText(word,new System.Globalization.CultureInfo("zh-cn"),FlowDirection.LeftToRight,fontSize,Brushes.black);
            Geometry geo = text.buildGeometry(new Point(0,0)); 
            PathGeometry path = geo.GetFlattenedPathGeometry();
            return path.ToString(); 
}@H_944_26@ 


 
用法：
 <Path x:Name="textPath" Canvas.Left="10" Canvas.Top="10" Fill="#FFFF0000" />
 

 C#代码：
 rootElement.findName('textPath').Data = GetTextPath("测试一下A Test!","方正大黑简体",42);
 


 
在SVG/Silverlight中使用，可以写成 WCF

using System.Runtime.serialization;
using System.serviceModel;
using System.serviceModel.Web;
using System.Text;

// 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“Iservice”。
[serviceContract]
public interface Iservice
{
    [OperationContract]
    String GetTextPath(FontParam cs);
}


[DataContract]
public class FontParam
{
    String word = "";
    String fontFamily = "宋体";
    int fontSize = 12;

    [DataMember]
    public String Word
    {
        get { return word; }
        set { word = value; }
    }

    [DataMember]
    public String FontFamily
    {
        get { return fontFamily; }
        set { fontFamily = value; }
    }

    [DataMember]
    public int FontSize
    {
        get { return fontSize; }
        set { fontSize = value; }
    }
}

 记得添加PresentationCore.dll和WindowsBase.dll的引用，这两个在.net 4.0 /wpf　的目录下 
 

 
 
 serviceReference1.serviceClient sc = new serviceReference1.serviceClient();
            serviceReference1.FontParam cs = new serviceReference1.Font@R_970_1403@;
            cs.FontSize = fontSize.AsInt();
            cs.FontFamily = fontFamily;
            cs.Word = word;
            haha = sc.GetTextPath(cs);@H_944_26@ 

 哈哈，这样就可以了！！
