Types

type HSV 

type HSV struct {
	Hue        uint8
	Saturation uint8
	Value      uint8
}

HSV struct represents HSV color model. Unlike traditional HSV representation using uint16 for Hue (0-360 range) and uint8 (0-100 range) for Saturation and Value, all fields in HSV struct are represented with uint8 (range from 0-255).

For details see https://en.wikipedia.org/wiki/HSL_and_HSV

func NewHSV 

func NewHSV(hue, saturation, value uint8) HSV

func NewHSVFromHEX 

func NewHSVFromHEX(color uint32) HSV

NewHSVFromHEX takes 0xRRGGBB uint32 (24-bit actually, no alpha channel) color value and returns instance of HSV.

func NewHSVFromRGB 

func NewHSVFromRGB(red, green, blue uint8) HSV

NewHSVFromRGB returns HSV instance created from the given red, green and blue colors.

func (HSV) RGB 

func (c HSV) RGB() RGB

RGB converts this HSV color to RGB color model.

type RGB 

type RGB struct {
	Red, Green, Blue uint8
}

RGB struct represents a 32-bit, having 8 bits for each of red, green and blue. Alpha is not supported.

func NewRGB 

func NewRGB(red, green, blue uint8) RGB

NewRGB returns RGB instance with the given red, green and blue colors.

func NewRGBFromHEX 

func NewRGBFromHEX(color uint32) RGB

NewRGBFromHEX takes 0xRRGGBB uint32 (24-bit actually, no alpha channel) color value and returns instance of RGB.

func NewRGBFromHSV 

func NewRGBFromHSV(hue, saturation, value uint8) RGB

NewRGBFromHSV returns RGB instance created from the given HSV values.

func (RGB) HSV 

func (c RGB) HSV() HSV

HSV converts this RGB color to HSV color model.
