func LinearGradient(size image.Point, startColor color.RGBA, endColor color.RGBA, direction Direction) *image.RGBA

LinearGradient generates a gradient image using a linear function.

func SigmoidalGradient(size image.Point, startColor color.RGBA, endColor color.RGBA, direction Direction) *image.RGBA
