Types ¶

type BGR ¶

type BGR struct {
	B, G, R uint8
}

BGR represents a traditional 32-bit alpha-premultiplied color, having 8 bits for each of red, green, blue.

func (BGR) RGBA ¶

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

type BGRImage ¶

type BGRImage struct {
	// Pix holds the image's pixels, in R, G, B order. The pixel at
	// (x, y) starts at Pix[(y-Rect.Min.Y)*Stride + (x-Rect.Min.X)*3].
	Pix []uint8
	// Stride is the Pix stride (in bytes) between vertically adjacent pixels.
	Stride int
	// Rect is the image's bounds.
	Rect image.Rectangle
}

BGRImage is an in-memory image whose At method returns RGB values.

func NewBGRImage ¶

func NewBGRImage(r image.Rectangle) *BGRImage

NewBGRImage returns a new BGRImage image with the given bounds.

func (BGRImage) At ¶

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

func (*BGRImage) BGRAt ¶

func (p *BGRImage) BGRAt(x, y int) BGR

	image.Image
	Mode() Mode
}

type Mode ¶

type Mode int

mode represents the image mode

const (
	RGBMode Mode = iota
	BGRMode
	NonInterlacedRGBMode
	NonInterlacedBGRMode
	InvalidMode Mode = 9999
)

type RGB ¶

type RGB struct {
