<RadialGradientBrush .../> paints an area with a radial gradient. The focal point is the beginning of the gradient, and a circle defines the outer boundary. RadialGradientBrush can be declared using abbreviated markup syntax as an attribute of an element:

 <element attribute="RadialGradientBrush InnerColor OuterColor" /> 

Figure 7-9 shows the result of evaluating Example 7-6, which uses a RadialGradientBrush.

Attributes

Center (optional)

A Point describing the location of the center of the radial gradient. The default is (0.5,0.5). Center may be described using abbreviated markup syntax or explicitly declared as a Point.

GradientOrigin (optional)

A Point describing the focal point of the gradient. The default is (0.5,0.5). GradientOrigin may be described using abbreviated markup syntax or explicitly declared as a Point. This value is between 0 and 1.0, inclusive.

RadialGradientStops (optional)

A collection of GradientStop elements specifying the location and color of each change in the gradient. This value is between 0 and 1.0, inclusive.

RadiusX (optional)

A Double value describing the horizontal outermost radius of the gradient. The default value is 0.5. This value is between 0 and 1.0, inclusive.

RadiusY (optional)

A Double value describing the vertical outermost radius of the gradient. The default value is 0.5. This value is between 0 and 1.0, inclusive.
