Types

type RGBAF64

type RGBAF64 struct {
	R, G, B, A float64
}

RGBAF64 represents an RGBA color using the range 0.0 to 1.0 with a float64 for each channel.

func NewRGBAF64

func NewRGBAF64(r, g, b, a uint8) RGBAF64

NewRGBAF64 returns a new RGBAF64 color based on the provided uint8 values. uint8 value 0 maps to 0, 128 to 0.5 and 255 to 1.0.

func (*RGBAF64) Clamp

func (c *RGBAF64) Clamp()

Clamp limits the channel values of the RGBAF64 color to the range 0.0 to 1.0.
