Details
The MaskBrush property is a reference to an instance of a Brush applied to a control to selectively apply transparency.
This allows for controls, particularly images, to fade out and blend in to the background.
In the case of a Linear Brush with a gradient from any color to transparent, the control will be become increasingly transparent. If using a Image Brush, transparency will be applied based on the transparency of the Image.
