Types ¶

type DIB ¶

type DIB struct {
	// Pix holds the image's pixels, in B, G, R order. The pixel at
	// (x, y) starts at Pix[(p.Rect.Max.Y-y-p.Rect.Min.Y-1)*p.Stride + (x-p.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
}

func NewDIB ¶

func NewDIB(r image.Rectangle) *DIB

func (*DIB) At ¶

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