What is radial gradient in Flash CS3

Radial gradients radiate from a center focal point. Both can be edited for color, alpha, and position within a fill or stroke. You can add up to 16 colors to a gradient, precisely control the location of the gradient focal point, and apply other parameters. A gradient behaves like any other fill or stroke.

it can either be 2. or 4. : ) tell me if i'm wrong or right
