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

func (*DIB) Bounds

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

func (*DIB) ColorModel

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

func (*DIB) CopyRGBA

func (p *DIB) CopyRGBA(src *image.RGBA, r image.Rectangle)

func (*DIB) Opaque

func (p *DIB) Opaque() bool

Opaque scans the entire image and returns whether or not it is fully opaque.

func (*DIB) PixOffset

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

PixOffset returns the index of the first element of Pix that corresponds to the pixel at (x, y).

func (*DIB) Set

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

func (*DIB) SetDIB
