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-null 参照 (Visual Basicでは Nothing) value enables the following properties:

• CenterOfEndCircle
• RadiusOfStartCircle
• ExtendStartCircle
• ExtendEndCircle
• Normalize

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

• CoverRectangle
• AllowEllipticGradients
