Types ¶

type BGR8 ¶

type BGR8 struct {
	// Pix holds the image's pixels, in R, G, B, A order. The pixel at
	// (x, y) starts at Pix[(y-Rect.Min.Y)*Stride + (x-Rect.Min.X)*4].
	Pix []uint8
	// Stride is the Pix stride (in bytes) between vertically adjacent pixels.
	Stride int
	// Rect is the image's bounds.
	Rect image.Rectangle
}

BGR8 is an in-memory image whose At method returns color.BGR8 values.

func NewBGR8 ¶

func NewBGR8(r image.Rectangle) *BGR8

NewBGR8 returns a new BGR8 image with the given bounds.

func TextToBGR8 ¶

func TextToBGR8(txtLines []string) *BGR8

func (*BGR8) At ¶

func (p *BGR8) At(x, y int) color.Color

func (*BGR8) BGR8At ¶

func (p *BGR8) BGR8At(x, y int) ColorBGR8

func (*BGR8) Bounds ¶

func (p *BGR8) Bounds() image.Rectangle

func (*BGR8) ColorModel ¶

func (p *BGR8) ColorModel() color.Model

func (*BGR8) NRGBAAt ¶

func (p *BGR8) NRGBAAt(x, y int) color.NRGBA

func (*BGR8) Opaque ¶

func (p *BGR8) Opaque() bool

Opaque scans the entire image and reports whether it is fully opaque.

func (*BGR8) PixOffset ¶

func (p *BGR8) PixOffset(x, y int) int

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

func (*BGR8) RGBA64At ¶

func (p *BGR8) RGBA64At(x, y int) color.RGBA64

func (*BGR8) Set ¶

func (p *BGR8) Set(x, y int, c color.Color)

func (*BGR8) SubImage ¶

func (p *BGR8) SubImage(r image.Rectangle) image.Image

SubImage returns an image representing the portion of the image p visible through r. The returned value shares pixels with the original image.
