The color of the associated stroke.
| XAML |
<DrawingAttributes Color="Color" .../>
|
| Scripting |
value = object.Color object.Color = value |
Property Value
The color of the associated stroke.
This property is read/write. The default value is Black.
Remarks
See Color for details on the various string formats that can be used to specify a color either in XAML or script.
Examples
The following JavaScript example simulates 3 different pen types (pen, marker and highlighter) by setting the Color, Height, OutlineColor and Width, DrawingAttributes properties . First a DrawingAttributes object is created, then it is appended to the Stroke object. The DrawingAttributes properties are then set by one of the three events that simulate a pen type. The EraseCanvas event clears all the Strokes from the Canvas.

The XAML sample below creates the canvas and 4 buttons that are used to select the different pen types and the erase all feature that is simulated by the Javascript events above.
