Usage
type RadialGradient
type RadialGradient struct {
StartColor color.Color // The beginning color of the gradient
EndColor color.Color // The end color of the gradient
// The offset of the center for generation of the gradient.
// This is not a DP measure but relates to the width/height.
// A value of 0.5 would move the center by the half width/height.
CenterOffsetX, CenterOffsetY float64
}
RadialGradient defines a Gradient travelling radially from a center point outward.
func NewRadialGradient
func NewRadialGradient(start, end color.Color) *RadialGradient
NewRadialGradient creates a new radial gradient.
func (*RadialGradient) Generate
