func DitherStep ¶

func DitherStep(im pixel.Image, step int)

func FadeOutDiagonal ¶

func FadeOutDiagonal(duration time.Duration, im pixel.Image) <-chan time.Time

func FadeOutDither ¶

func FadeOutDither(duration time.Duration, im pixel.Image) <-chan time.Time

FadeOutDither dims the colors by dithering, most useful for 1-bit bitmaps.

func FadeOutHorizontal ¶

func FadeOutHorizontal(duration time.Duration, im pixel.Image) <-chan time.Time

FadeOutVertical draws horizontal raster lines to fade out the image.

func FadeOutShift ¶

func FadeOutShift(duration time.Duration, im pixel.Image) <-chan time.Time

FadeOutShift dims the colors by bit shifting. 1-bit bitmaps are ignored.

func FadeOutVertical ¶

func FadeOutVertical(duration time.Duration, im pixel.Image) <-chan time.Time

FadeOutVertical draws vertical raster lines to fade out the image.

func ShiftRight ¶

func ShiftRight(im pixel.Image)
