Functions

func TempFile

func TempFile(size int64) (*os.File, error)

Types

type BGRA

type BGRA struct {
	Pix    []uint8
	Stride int
	Rect   image.Rectangle
}

BGRA is like RGBA but in wayland's byte order

func NewBGRA

func NewBGRA(r image.Rectangle) *BGRA

NewBGRA returns a new BGRA image with the given bounds.

func NewBGRAWithData

func NewBGRAWithData(r image.Rectangle, data []uint8) *BGRA

func (*BGRA) At

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

func (*BGRA) Bounds

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

func (*BGRA) ColorModel

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

func (*BGRA) Opaque

func (p *BGRA) Opaque() bool

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

func (*BGRA) Painter

func (p *BGRA) Painter() *BGRAPainter

func (*BGRA) PixOffset

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

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

func (*BGRA) RGBAAt

func (p *BGRA) RGBAAt(x, y int) color.RGBA

func (*BGRA) Set

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

func (*BGRA) SetRGBA

func (p *BGRA) SetRGBA(x, y int, c color.RGBA)

func (*BGRA) SubImage

func (p *BGRA) 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.

type BGRAPainter

type BGRAPainter struct {
	// contains filtered or unexported fields
}

a BGRAPainter is used to interface with the freetype renderer and raster library
