var HSVAModel color.Model = color.ModelFunc(hsvaModel)

HSVAModel converts any color.Color to an HSVA color.

Types

type HSVA

type HSVA struct {
	H, S, V, A float64
}

HSVAColor represents a Hue/Saturation/Value/Alpha color. H is valid within [0°, 360°]. S, V and A are valid within [0, 1].

func RGBAtoHSVA

func RGBAtoHSVA(r, g, b, a uint32) HSVA

Convert r, g, b, a to HSVA

func (HSVA) RGBA

func (self HSVA) RGBA() (r, g, b, a uint32)

RGBA() allows HSVAColor to satisfy the color.Color interface.
