Functions

func MulAlpha

func MulAlpha(c color.NRGBA, alpha uint8) color.NRGBA

MulAlpha scales all color components by alpha/255.

Types

type RGBA

type RGBA struct {
	R, G, B, A float32
}

RGBA is a 32 bit floating point linear space color.

func RGBAFromSRGB

func RGBAFromSRGB(col color.RGBA) RGBA

RGBAFromSRGB converts from SRGBA to RGBA.

func (RGBA) Array

func (col RGBA) Array() [4]float32

Array returns rgba values in a [4]float32 array.

func (RGBA) Float32

func (col RGBA) Float32() (r, g, b, a float32)

Float32 returns r, g, b, a values.

func (RGBA) Opaque

func (col RGBA) Opaque() RGBA

Opaque returns the color without alpha component.

func (RGBA) SRGB

func (col RGBA) SRGB() color.RGBA

SRGB converts from linear to sRGB color space.
