IDOMRadialGradientBrush interface. A radial gradient brush defines an ellipse to be filled with the gradient. The ellipse is defined by its center, x radius, and y radius. Independently, a gradient origin is specified for the brush. The gradient origin defines the center of the gradient; a gradient stop with an offset at 0.0 defines the color at the gradient origin. The outer bound of the ellipse defines the end "point" of the gradient; that is, a gradient stop with an offset at 1.0 defines the color at the circumference of the ellipse, and all other gradient stops define their offsets relative to the radial distance between the gradient origin and the circumference.

Detailed Description

IDOMRadialGradientBrush interface. A radial gradient brush defines an ellipse to be filled with the gradient. The ellipse is defined by its center, x radius, and y radius. Independently, a gradient origin is specified for the brush. The gradient origin defines the center of the gradient; a gradient stop with an offset at 0.0 defines the color at the gradient origin. The outer bound of the ellipse defines the end "point" of the gradient; that is, a gradient stop with an offset at 1.0 defines the color at the circumference of the ellipse, and all other gradient stops define their offsets relative to the radial distance between the gradient origin and the circumference.
