After my initial port
, alpha-numeric letters could not be rendered as the FormattedText object is not available within Silverlight. This left me with the following options:
- Call a web service to dynamically convert the letters to the associated XAML path for a defines font.
- Create a small WPF application that generates the XAML path geometry and embed this in a C# dictionary object within the code.
The second of the two options was the quickest (code snippet below). In the future another enhancement could look at creating web service or using a xap file with different fonts.
The next piece to the process was to load the path data into a Geometry instance. Using Alex Golesh's PathFigureCollectionConverter the shapes are now loaded and the updated version now supports generation of letters. One problem I have now if that the closed in shapes are not rendering properly i.e. the O is a solid oval.
var code = new StringBuilder();
code.Append("var arial = new Dictionary<string, string>();\r\n");
var lettersToCreate = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
for (var i = 0;i < lettersToCreate.Length; i++)
var letter = lettersToCreate.Substring(i, 1);
var fText = new FormattedText(
var g = fText.BuildGeometry(new Point(0, 0)).GetAsFrozen() as Geometry;
// Get the Path info from the geometry
var p = g.GetFlattenedPathGeometry();
code.Append("arial.Add(\"" + letter + "\", \"" + p.ToString().Replace("F1M", "M ") + "\");\r\n");
