 DrawingBrush opacity masking example  
   
- The gradient brushes (<xref:System.Windows.Media.LinearGradientBrush> and <xref:System.Windows.Media.RadialGradientBrush>) are particularly well-suited for use as an opacity mask. Because a <xref:System.Windows.Media.SolidColorBrush> fills an area with a uniform color, they make poor opacity masks; using a <xref:System.Windows.Media.SolidColorBrush> is equivalent to setting the element's or visual's <xref:System.Windows.UIElement.OpacityMask%2A> property.
