type Gray32 struct {
	Pix    []uint8
	Stride int
	Rect   image.Rectangle
	Min    float32
	Max    float32
}

Gray32 represents an image.Image encoded in 32b IEEE floating-point values

func NewGray32(rect image.Rectangle, pix []byte) *Gray32

NewGray32 creates a new Gray32 image with the given bounds.

func (p *Gray32) At(x, y int) color.Color

func (p *Gray32) Bounds() image.Rectangle

func (p *Gray32) ColorModel() color.Model

func (p *Gray32) PixOffset(x, y int) int

func (p *Gray32) Set(x, y int, c color.Color)

type Gray64 struct {
	Pix    []uint8
	Stride int
	Rect   image.Rectangle
	Min    float64
	Max    float64
}

Gray64 represents an image.Image encoded in 64b IEEE floating-point values

func NewGray64(rect image.Rectangle, pix []byte) *Gray64

NewGray64 creates a new Gray64 image with the given bounds.

func (p *Gray64) At(x, y int) color.Color

func (p *Gray64) Bounds() image.Rectangle

func (p *Gray64) ColorModel() color.Model
