Functions

func Lerp

func Lerp(a, b, ratio float64) float64

The ratio is capped between 0 and 1

func LerpColor

func LerpColor(a, b color.RGBA, ratio float64) color.RGBA

Creates a color between the given a and b. 0 means a is given, 1 means b is given, .5 is a color half way between. The ratio is capped between 0 and 1 Currently the function floors the number instead of rounding to nearest.

func LerpUint8

func LerpUint8(a, b uint8, ratio float64) uint8

The ratio is capped between 0 and 1 Currently the function floors the number instead of rounding to nearest.
