Types

type Gray1

type Gray1 struct {
	Y bool
}

Gray1 represents an 1-bit monochrome bitmap color.

func (Gray1) RGBA

func (c Gray1) RGBA() (r, g, b, a uint32)

RGBA implements color.Color interface's method.

type Gray32

type Gray32 struct {
	Y float32
}

Gray32 represents a 32-bit float grayscale color.

func (Gray32) RGBA

func (c Gray32) RGBA() (r, g, b, a uint32)

RGBA implements color.Color interface's method.

type NCMYKA

type NCMYKA struct {
	C, M, Y, K, A uint8
}

NCMYKA represents a non-alpha-premultiplied CMYK color, having 8 bits for each of cyan, magenta, yellow, black and alpha. NCMYKA is different from color.CMYK, CMYK is inverted value.

It is not associated with any particular color profile.

func (NCMYKA) RGBA

func (c NCMYKA) RGBA() (uint32, uint32, uint32, uint32)

RGBA implements color.Color interface's method.
