Convert Silverlight Text to Path
Is it possible to convert Silverlight text to path or graphic at runtime ? I know it can be done with design tools, but I want to be able to do it on the fly.
I saw an example of what calls a web service that uses WPF constructors to convert a WPF FormattedText object to a PathGeometry , but these objects are not available in Silverlight.
I'm sure this is simply not supported in Silverlight, but thought it might be worth asking.

Here is the dynamic geometry code for the SilverLight path. or creating a SilverLight path from a string. Just paste the below method into a new class or an existing class and it will be ready to use. you can find sample code for using these functions at the bottom of the method.
/// Method tested with SilverLight 2.0
// this method will generates path with the data string
public PathGeometry getPathGeometry(string data)
{
PathGeometry pg = new PathGeometry();
PathSegmentCollection psc = new PathSegmentCollection();
PathFigure pf = new PathFigure();
PathFigureCollection pfc = new PathFigureCollection();
data= data.Replace("M "," M").Replace("C "," C").Replace("L "," L");
string[] str = data.Split(' ');
for (int i = 0; i < str.Length; i++)
{
if (str[i].StartsWith("C") || str[i].StartsWith("c"))
{
string[] item = str[i].Split(',');
string[] item1 = str[i + 1].Split(',');
string[] item2 = str[i + 2].Split(',');
BezierSegment bs = new BezierSegment();
bs.Point1 = new Point(double.Parse(item[0].Substring(1)), double.Parse(item[1]));
bs.Point2 = new Point(double.Parse(item1[0]), double.Parse(item1[1]));
bs.Point3 = new Point(double.Parse(item2[0]), double.Parse(item2[1]));
i += 2;
psc.Add(bs);
}
else if (str[i].StartsWith("L") || str[i].StartsWith("l"))
{
string[] item = str[i].Split(',');
LineSegment ls = new LineSegment();
ls.Point = new Point(double.Parse(item[0].Substring(1)), double.Parse(item[1]));
psc.Add(ls);
}
else if (str[i].StartsWith("M") || str[i].StartsWith("m"))
{
string[] item = str[i].Split(',');
pf.StartPoint = new Point(double.Parse(item[0].Substring(1)), double.Parse(item[1]));
}
else if (str[i].StartsWith("z") || str[i].StartsWith("Z"))
{
pf.IsClosed = true;
}
}
pf.Segments = psc;
pfc.Add(pf);
pg.Figures = pfc;
return pg;
}
///// End of Method
