Functions ¶

func Difference ¶

func Difference(reference, sample Oklab) (deltaEOK float32)

Types ¶

type LCh ¶

type LCh struct {
	L float32
	C float32
	H float32
	A float32
}

func (LCh) Lab ¶

func (c LCh) Lab() Lab

type Lab ¶

type Lab struct {
	L     float32
	A     float32
	B     float32
	Alpha float32
}

func (Lab) LCh ¶

func (c Lab) LCh() LCh

type LinearSRGB ¶

type LinearSRGB RGB

func (LinearSRGB) Oklab ¶

func (c LinearSRGB) Oklab() Oklab

func (LinearSRGB) SRGB ¶

func (c LinearSRGB) SRGB() SRGB

type Oklab ¶

type Oklab Lab

func (Oklab) LinearSRGB ¶

func (c Oklab) LinearSRGB() LinearSRGB

LinearSRGB converts from Oklab to linear sRGB, without applying gamut mapping. That is, if the color falls outside the sRGB gamut, the resulting R, G, and B channels may have values larger than 1 or less than 0. You can use Oklch.MapToSRGBGamut to prevent this from happening.

func (Oklab) Oklch ¶

func (c Oklab) Oklch() Oklch

type Oklch ¶

type Oklch LCh

func (Oklch) MapToSRGBGamut ¶

func (c Oklch) MapToSRGBGamut() LinearSRGB

MapToSRGBGamut maps colors that fall outside the sRGB gamut to the sRGB gamut. It uses the same algorithm as CSS Color Module Level 4. Note that the mapping implements a relative colorimetric intent. That is, colors that are already inside the gamut are unchanged. This is intended for mapping individual colors, not for mapping images.

func (Oklch) NRGBA ¶ added in v0.4.0

func (c Oklch) NRGBA() color.NRGBA

func (Oklch) Oklab ¶

func (c Oklch) Oklab() Oklab

type RGB ¶

type RGB struct {
	R float32
	G float32
	B float32
	A float32
}

type SRGB ¶

type SRGB RGB

func (SRGB) HTML ¶

func (c SRGB) HTML() string

func (SRGB) LinearSRGB ¶

func (c SRGB) LinearSRGB() LinearSRGB

func (SRGB) RGBA ¶

func (c SRGB) RGBA() (r, g, b, a uint32)
