Variables

var NHSVAModel color.Model = color.ModelFunc(nhsvaModel)

NHSVAModel is a color model for NHSVA (non-alpha-premultiplied hue, saturation, and value plus alpha) colors.

Types

type NHSVA

type NHSVA struct {
	H, S, V, A uint8
}

NHSVA represents a non-alpha-premultiplied 32-bit HSV color. Note that all color channels range from 0 to 255. (It is more common for hue to range from 0 to 359 and saturation and value to range from 0 to 1, but that's not what we do here.)

func (NHSVA) RGBA

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

RGBA converts an NHSVA color to alpha-premultiplied RGBA.
