Gets or sets the radius of the end circle that defines the end of the gradient, as a fraction of the normalized diagonal. The normalized diagonal length is calculated as sqrt(width² + height²) / sqrt(2).

Setting this property to a non-a null reference (Nothing in Visual Basic) value enables the following properties:

• CenterOfEndCircle
• RadiusOfStartCircle
• ExtendStartCircle
• ExtendEndCircle
• Normalize

And the following properties are ignored if this property has a value:

• CoverRectangle
• AllowEllipticGradients
